We all know stories of tobacco, asbestos, and DDT. Originally declared safe, they caused widespread death and disease. Although their impact was vast, most of the population was spared. The same cannot be said for sweeping changes in the food supply. Everyone eats; everyone is affected. The increase in several diseases in North America may be due to the profound changes in our diet. The most radical change occurred a little over a decade ago when genetically modified (GM) crops were introduced. Their influence on health has been largely ignored, but recent studies show serious problems. Genetically modified organisms (GMOs) have been linked to thousands of toxic or allergic-type reactions, thousands of sick, sterile, and dead livestock, and damage to virtually every organ and system studied in lab animals.1 Nearly every independent animal feeding safety study shows adverse or unexplained effects.
GM foods were made possible by a technology developed in the 1970s whereby genes from one species are forced into the DNA of other species. Genes produce proteins, which in turn can generate characteristics or traits. The promised traits associated with GMOs have been sky high—vegetables growing in the desert, vitamin fortified grains, and highly productive crops feeding the starving millions. None of these are available. In fact, the only two traits that are found in nearly all commericialized GM plants are herbicide tolerance and/or pesticide production.
Herbicide tolerant soy, corn, cotton, and canola plants are engineered with bacterial genes that allow them to survive otherwise deadly doses of herbicides. This gives farmers more flexibility in weeding and gives the GM seed company lots more profit. When farmers buy GM seeds, they sign a contract to buy only that seed producer’s brand of herbicide. Herbicide tolerant crops comprise about 80% of all GM plants. The other 20% are corn and cotton varieties that produce a pesticide in every cell. This is accomplished due to a gene from a soil bacterium called Bacillus thuringiensis or Bt, which produces a natural insect-killing poison called Bt-toxin. In addition to these two traits, there are also disease resistant GM Hawaiian papaya, zucchini and crook neck squash, which comprise well under 1% of GMO acreage.
THE FDA’S “NON-REGULATION” OF GM FOODS
Rhetoric from the United States government since the early 1990s proclaims that GM foods are no different from their natural counterparts that have existed for centuries. The Food and Drug Administration (FDA) has labeled them “Generally Recognized as Safe,” or GRAS. This status allows a product to be commercialized without any additional testing. According to US law, to be considered GRAS the substance must be the subject of a substantial amount of peer-reviewed published studies (or equivalent) and there must be overwhelming consensus among the scientific community that the product is safe. GM foods had neither. Nonetheless, in a precedent- setting move in 1992 that some experts contend was illegal, the FDA declared that GM crops are GRAS as long as their producers say they are. Thus, the FDA does not require any safety evaluations or labeling of GMOs. A company can even introduce a GM food to the market without telling the agency.
Such a lenient approach was largely the result of the influence of large agricultural corporations According to Henry Miller, who had a leading role in biotechnology issues at the FDA from 1979 to 1994, “In this area, the US government agencies have done exactly what big agribusiness has asked them to do and told them to do.” The Ag biotech company with the greatest influence was clearly Monsanto. According to the New York Times, “What Monsanto wished for from Washington, Monsanto and, by extension, the biotechnology industry got. . . . When the company abruptly decided that it needed to throw off the regulations and speed its foods to market, the White House quickly ushered through an unusually generous policy of self- policing.”
This policy was heralded by Vice President Dan Quayle on May 26, 1992. He chaired the Council on Competitiveness, which had identified GM crops as an industry that could boost US exports. To take advantage, Quayle announced “reforms” to “speed up and simplify the process of bringing” GM products to market without “being hampered by unnecessary regulation.”2 Three days later, the FDA policy on non-regulation was unveiled.
The person who oversaw its development was the FDA’s Deputy Commissioner for Policy, Michael Taylor, whose position had been created especially for him in 1991. Prior to that, Taylor was an outside attorney for both Monsanto and the Food Biotechnology Council. After working at the FDA, he became Monsanto’s vice president.
THE FDA COVERS UP HEALTH RISKS
Taylor’s policy needed to create the impression that unintended effects from GM crops were not an issue. Otherwise their GRAS status would be undermined and they would need the extensive testing and labels that are normally required for food additives. But internal memos made public from a lawsuit showed that the overwhelming consensus among the agency scientists was that GM crops can have unpredictable, hard-to-detect side effects. Various departments and experts spelled these out in detail, listing allergies, toxins, nutritional effects, and new diseases as potential dangers. They urged superiors to require long-term safety studies.3 In spite of the warnings, according to public interest attorney Steven Druker who studied the FDA’s internal files, “References to the unintended negative effects of bioengineering were progressively deleted from drafts of the policy statement (over the protests of agency scientists).”4
FDA microbiologist Louis Pribyl, PhD, wrote about the policy, “What has happened to the scientific elements of this document? Without a sound scientific base to rest on, this becomes a broad, general, ‘What do I have to do to avoid trouble’-type document. . . . It will look like and probably be just a political document. . . . It reads very pro-industry, especially in the area of unintended effects.”5
The scientists’ concerns were not only ignored, their very existence was denied. The official FDA policy stated, “The agency is not aware of any information showing that foods derived by these new methods differ from other foods in any meaningful or uniform way.”6 In sharp contrast, an internal FDA report stated, “The processes of genetic engineering and traditional breeding are different and according to the technical experts in the agency, they lead to different risks.”7 The FDA’s deceptive notion of no difference was coined “substantial equivalence” and formed the basis of the US government position on GMOs.
Many scientists and organizations have criticized the US position. The National Academy of Sciences and even the pro-GM Royal Society of London8 describe the US system as inadequate and flawed. The editor of the prestigious journal Lancet said, “It is astounding that the US Food and Drug Administration has not changed their stance on genetically modified food adopted in 1992. . . . The policy is that genetically modified crops will receive the same consideration for potential health risks as any other new crop plant. This stance is taken despite good reasons to believe that specific risks may exist. . . . Governments should never have allowed these products into the food chain without insisting on rigorous testing for effects on health.”9 The Royal Society of Canada described substantial equivalence as “scientifically unjustifiable and inconsistent with precautionary regulation of the technology.” 10
GMOS ARE INHERENTLY UNSAFE
There are several reasons why GM plants present unique dangers. The first is that the process of genetic engineering itself creates unpredicted alterations, irrespective of which gene is transferred. The gene insertion process, for example, is accomplished by either shooting genes from a “gene gun” into a plate of cells, or using bacteria to infect the cell with foreign DNA. Both create mutations in and around the insertion site and elsewhere.11 The “transformed” cell is then cloned into a plant through a process called tissue culture, which results in additional hundreds or thousands of mutations throughout the plants’ genome. In the end, the GM plant’s DNA can be a staggering 2-4% different from its natural parent.12 Native genes can be mutated, deleted, or permanently turned on or off. In addition, the insertion process causes holistic and not-well-understood changes among large numbers of native genes. One study revealed that up to 5% of the natural genes altered their levels of protein expression as a result of a single insertion.
The Royal Society of Canada acknowledged that “the default prediction” for GM crops would include “a range of collateral changes in expression of other genes, changes in the pattern of proteins produced and/or changes in metabolic activities.”13 Although the FDA scientists evaluating GMOs in 1992 were unaware of the extent to which GM DNA is damaged or changed, they too described the potential consequences. They reported, “The possibility of unexpected, accidental changes in genetically engineered plants” might produce “unexpected high concentrations of plant toxicants.”14 GM crops, they said, might have “increased levels of known naturally occurring toxins,” and the “appearance of new, not previously identified” toxins.15 The same mechanism can also produce allergens, carcinogens, or substances that inhibit assimilation of nutrients.
Most of these problems would pass unnoticed through safety assessments on GM foods, which are largely designed on the false premise that genes are like Legos that cleanly snap into place. But even if we disregard unexpected changes in the DNA for the moment, a proper functioning inserted gene still carries significant risk. Its newly created GM protein, such as the Bt-toxin, may be dangerous for human health (see below). Moreover, even if that protein is safe in its natural organism, once it is transferred into a new species it may be processed differently. A harmless protein may be transformed into a dangerous or deadly version. This happened with at least one GM food crop under development, GM peas, which were destroyed before being commercialized.
FDA scientists were also quite concerned about the possibility of inserted genes spontaneously transferring into the DNA of bacteria inside our digestive tract. They were particularly alarmed at the possibility of antibiotic resistant marker (ARM) genes transferring. ARM genes are employed during gene insertion to help scientists identify which cells successfully integrated the foreign gene. These ARM genes, however, remain in the cell and are cloned into the DNA of all the GM plants produced from that cell. One FDA report wrote in all capital letters that ARM genes would be “A SERIOUS HEALTH HAZARD,” due to the possibility of that they might transfer to bacteria and create super diseases, untreatable with antibiotics.
Although the biotech industry confidently asserted that gene transfer from GM foods was not possible, the only human feeding study on GM foods later proved that it does take place. The genetic material in soybeans that make them herbicide tolerant transferred into the DNA of human gut bacteria and continued to function. That means that long after we stop eating a GM crop, its foreign GM proteins may be produced inside our intestines. It is also possible that the foreign genes might end up inside our own DNA, within the cells of our own organs and tissues.
Another worry expressed by FDA scientists was that GM plants might gather “toxic substances from the environment” such as “pesticides or heavy metals,”16 or that toxic substances in GM animal feed might bioaccumulate into milk and meat products. While no studies have looked at the bioaccumulation issue, herbicide tolerant crops certainly have higher levels of herbicide residues. In fact, many countries had to increase their legally allowable levels—by up to 50 times—in order to accommodate the introduction of GM crops.
The overuse of the herbicides due to GM crops has resulted in the development of herbicide resistant weeds. USDA statistics show that herbicide use is rapidly accelerating. Its use was up by 138 million pounds in the first nine years of GM crops.17 But over the next two years, it jumped by another 120 million pounds (estimated). Between 2005 and 2006, the use of Roundup herbicide—used on GM Roundup Ready crops—was up by 38%. And because Roundup is becoming less effective on weeds, farmers are now using more toxic herbicides, such as 2-4D, which has increased by 237% from 2004 to2006.18
All of the above risks associated with GM foods are magnified for high-risk groups, such as pregnant women, children, the sick, and the elderly. The following section highlights some of the problems that have been identified.
GM DIET SHOWS TOXIC REACTIONS IN THE DIGESTIVE TRACT
The very first crop submitted to the FDA’s voluntary consultation process, the FlavrSavr tomato, showed evidence of toxins. Out of 20 female rats fed the GM tomato, 7 developed stomach lesions.19 The director of FDA’s Office of Special Research Skills wrote that the tomatoes did not demonstrate a “reasonable certainty of no harm,”20 which is their normal standard of safety. The Additives Evaluation Branch agreed that “unresolved questions still remain.”21 The political appointees, however, did not require that the tomato be withdrawn.
[[Note: Calgene had submitted data on two lines of GM tomatoes, both using the same inserted gene. They voluntarily elected to market only the variety that was not associated with the lesions. This was not required by the FDA, which did not block approvals on the lesion- associated variety. The FlavrSavr tomato has since been taken off the market. After the FlavrSavr, no other biotech company has submitted such detailed data to the FDA.]]
According to Arpad Pusztai, PhD, one of the world’s leading experts in GM food safety assessments, the type of stomach lesions linked to the tomatoes “could lead to life-endangering hemorrhage, particularly in the elderly who use aspirin to prevent [blood clots].”22 Dr. Pusztai believes that the digestive tract, which is the first and largest point of contact with foods, can reveal various reactions to toxins and should be the first target of GM food risk assessment. He was alarmed, however, to discover that studies on the FlavrSavr never looked passed the stomach to the intestines. Other studies that did look found problems.
Mice fed potatoes engineered to produce the Bt-toxin developed abnormal and damaged cells, as well as proliferative cell growth in the lower part of their small intestines (ileum).23 Rats fed potatoes engineered to produce a different type of insecticide (GNA lectin from the snowdrop plant) also showed proliferative cell growth in both the stomach and intestinal walls (see photos).24 Although the guts of rats fed GM peas were not examined for cell growth, the intestines were mysteriously heavier; possibly as a result of such growth.25 Cell proliferation can be a precursor to cancer and is of special concern.
Illustration here: Rats fed GM potatoes showed proliferative cell growth in the stomach and intestines
GM DIETS CAUSE LIVER DAMAGE
The state of the liver—a main detoxifier for the body—is another indicator of toxins. *Rats fed the GNA lectin potatoes described above had smaller and partially atrophied livers.26 *Rats fed Monsanto’s Mon 863 corn, engineered to produce Bt-toxin, had liver lesions and other indications of toxicity.27 *Rabbits fed GM soy showed altered enzyme production in their livers as well as higher metabolic activity.28 *The livers of rats fed Roundup Ready canola were 12%–16% heavier, possibly due to liver disease or inflammation.29 *Microscopic analysis of the livers of mice fed Roundup Ready soybeans revealed altered gene expression and structural and functional changes (see photos).30 Many of these changes reversed after the mice diet was switched to non-GM soy, indicating that GM soy was the culprit. The findings, according to molecular geneticist Michael Antoniou, PhD, “are not random and must reflect some ‘insult’ on the liver by the GM soy.” Antoniou, who does human gene therapy research in King’s College London, said that although the long-term consequences of the GM soy diet are not known, it “could lead to liver damage and consequently general toxemia.”31
Illustration here: The liver cells from soy-fed mice showed anomalies and unique changes
GM FED ANIMALS HAD HIGHER DEATH RATES AND ORGAN DAMAGE
In the FlavrSavr tomato study, a note in the appendix indicated that 7 of 40 rats died within two weeks and were replaced.33 In another study, chickens fed the herbicide tolerant “Liberty Link” corn died at twice the rate of those fed natural corn.34 But in these two industry-funded studies, the deaths were dismissed without adequate explanation or follow-up.
In addition, the cells in the pancreas of mice fed Roundup Ready soy had profound changes and produced significantly less digestive enzymes;35 in rats fed a GM potato, the pancreas was enlarged.36 In various analyses of kidneys, GM-fed animals showed lesions, toxicity, altered enzyme production or inflammation.37,38 Enzyme production in the hearts of mice was altered by GM soy.39 And GM potatoes caused slower growth in the brain of rats. 40
REPRODUCTIVE FAILURES AND INFANT MORTALITY
The testicles of both mice and rats fed Roundup Ready soybeans showed dramatic changes. In rats, the organs were dark blue instead of pink (see photos on next page).41 In mice, young sperm cells were altered. 42 Embryos of GM soy-fed mice also showed temporary changes in their DNA function, compared to those whose parents were fed non-GM soy.43
[Illustration here: The testicles of rats fed Roundup Ready soybeans were dark blue instead of pink, and the structure of the cells were significantly altered.]
More dramatic results were discovered by a leading scientist at the Russian National Academy of sciences. Female rats were fed GM soy, starting two weeks before they were mated.
*Over a series of three experiments, 51.6 percent of the offspring from the GM-fed group died within the first three weeks, compared to 10 percent from the non-GM soy group, and 8.1 percent for non-soy controls. *“High pup mortality was characteristic of every litter from mothers fed the GM soy flour.”44 *The average size and weight of the GM-fed offspring was quite a bit smaller (see photo on next page).45 *In a preliminary study, the GM-fed offspring were unable to conceive.46
After the three feeding trials, the supplier of rat food used at the Russian laboratory began using GM soy in their formulation. Since all the rats housed at the facility were now eating GM soy, no non-GM fed controls were available for subsequent GM feeding trials; follow- up studies were canceled. After two months on the GM soy diet, however, the infant mortality rate of rats throughout the facility had skyrocketed to 55.3 percent (99 of 179).47
[Illustration here: The 20 day old smaller rat, born of amother fed GM soy, is quite a bit smaller than the 19 day-old rat from the control group.]
FARMERS REPORT LIVESTOCK STERILITY AND DEATHS
About two dozen farmers reported that their pigs had reproductive problems when fed certain varieties of Bt corn. Pigs were sterile, had false pregnancies, or gave birth to bags of water. Cows and bulls also became sterile. Bt corn was also implicated by farmers in the deaths of cows, horses, water buffaloes, and chickens.48
When Indian shepherds let their sheep graze continuously on Bt cotton plants, within 5-7 days, one out of four sheep died. There was an estimated 10,000 sheep deaths in the region in 2006, with more reported in 2007. Post mortems on the sheep showed severe irritation and black patches in both intestines and liver (as well as enlarged bile ducts). Investigators said preliminary evidence “strongly suggests that the sheep mortality was due to a toxin. . . . most probably Bt-toxin.”49
GM CROPS TRIGGER IMMUNE REACTIONS AND MAY CAUSE ALLERGIES
Allergic reactions occur when the immune system interprets something as foreign, different, and offensive, and reacts accordingly. All GM foods, by definition, have something foreign and different. And several studies show that they provoke reactions. Rats fed Monsanto’s GM corn, for example, had a significant increase in blood cells related to the immune system.50 GM potatoes caused the immune system of rats to respond more slowly.51 And GM peas provoked an inflammatory response in mice, suggesting that it might cause deadly allergic reactions in people.52
It might be difficult to identify whether GM foods were triggering allergic responses in the population, since very few countries conduct regular studies or keep careful records. One country that does have an annual evaluation is the UK. Soon after GM soy was introduced into the British diet, researchers at the York Laboratory reported that allergies to soy had skyrocketed by 50% in a single year.53 Although no follow-up studies were conducted to see if GM soy was the cause, there is evidence showing several ways in which it might have contributed to the rising incidence of allergies:
• The only significant variety of GM soy is Monsanto’s “Roundup Ready” variety, planted in 89% of US soy acres. A foreign gene from bacteria (with parts of virus and petunia DNA) is inserted, which allows the plant to withstand Roundup herbicide. The protein produced by the bacterial gene has never been part of the human food supply. Because people aren’t usually allergic to a food until they have eaten it several times, it would be difficult to know in advance if the protein was an allergen. Without a surefire method to identify allergenic GM crops, the World Health Organization (WHO) and others recommend examining the properties of the protein to see if they share characteristics with known allergens. One method is to compare the amino acid sequence of the novel protein with a database of allergens. If there is a match, according to the WHO, the GM crop should either not be commercialized or additional testing should be done. Sections of the protein produced in GM soy are identical to shrimp and dust mite allergens,54 but the soybean was introduced before WHO criteria were established and the recommended additional tests were not conducted. If the protein does trigger reactions, the danger is compounded by the finding that the Roundup Ready gene transfers into the DNA of human gut bacteria and may continuously produce the protein from within our intestines.55
• In addition to the herbicide tolerant protein, GM soybeans contain a unique, unexpected protein, which likely came about from the changes incurred during the genetic engineering process. Scientists found that this new protein was able to bind with IgE antibodies, suggesting that it may provoke dangerous allergic reactions. The same study revealed that one human subject showed a skin prick immune response only to GM soy, but not to natural soy.56 Another study showed that the levels of one known soy allergen, called trypsin inhibitor, were as much as seven times higher in cooked GM soy compared to a non-GM control.57
• GM soy also produces an unpredicted side effect in the pancreas of mice—the amount of digestive enzymes produced is dramatically reduced.58 If a shortage of enzymes caused food proteins to breakdown more slowly, then they have more time to trigger allergic reactions. Thus, digestive problems from GM soy might promote allergies to a wide range of proteins, not just soy.
• The higher amount of Roundup herbicide residues on GM soy might create reactions in consumers. In fact, many of the symptoms identified in the UK soy allergy study are among those related to glyphosate exposure. [The allergy study identified irritable bowel syndrome, digestion problems, chronic fatigue, headaches, lethargy, and skin complaints, including acne and eczema, all related to soy consumption. Symptoms of glyphosate exposure include nausea, headaches, lethargy, skin rashes, and burning or itchy skin. It is also possible that glyphosate’s breakdown product AMPA, which accumulates in GM soybeans after each spray, might contribute to allergies.]
It is interesting to note that in the five years immediately after GM soy was introduced, US peanut allergies doubled. It is known that a protein in natural soybeans cross-reacts with peanut allergies, i.e. soy may trigger reactions in some people who are allergic to peanuts. 59 Given the startling increase in peanut allergies, scientists should investigate whether this cross-reactivity has been amplified in GM soy.
BT-TOXIN, PRODUCED IN GM CORN AND COTTON, MAY CAUSE ALLERGIES
For years, organic farmers and others have sprayed crops with solutions containing natural Bt bacteria as a method of insect control. The toxin creates holes in their stomach and kills them. Genetic engineers take the gene that produces the toxin in bacteria and insert it into the DNA of crops so that the plant does the work, not the farmer. The fact that we consume that toxic pesticide in every bite of Bt corn is hardly appetizing.
Biotech companies claim that Bt-toxin has a history of safe use, is quickly destroyed in our stomach, and wouldn’t react with humans or mammals in any event. Studies verify, however, that natural Bt-toxin is not fully destroyed during digestion and does react with mammals. Mice fed Bt-toxin, for example, showed an immune response as potent as cholera toxin, 60, became immune sensitive to formerly harmless compounds,61 and had damaged and altered cells in their small intestines.62 Moreover, when natural Bt was sprayed over areas around Vancouver and Washington State to fight gypsy moths, about 500 people reported reactions—mostly allergy or flu-like symptoms.63,64 Farm workers and others also report serious reactions 65,66,67,68,69 and authorities have long acknowledged that “people with compromised immune systems or preexisting allergies may be particularly susceptible to the effects of Bt. 70
The Bt-toxin produced in GM crops is “vastly different from the bacterial [Bt-toxins] used in organic and traditional farming and forestry.”71 The plant produced version is designed to be more toxic than natural varieties,72 and is about 3,000-5,000 times more concentrated than the spray form. And just like the GM soy protein, the Bt protein in GM corn varieties has a section of its amino acid sequence identical to a known allergen (egg yolk). The Bt protein also fails other allergen criteria recommended by the WHO, i.e. the protein is too resistant to break down during digestion and heat.
If Bt-toxin causes allergies, then gene transfer carries serious ramifications. If Bt genes relocate to human gut bacteria, our intestinal flora may be converted into living pesticide factories, possibly producing Bt-toxin inside of us year after year. The UK Joint Food Safety and Standards Group also described gene transfer from a different route. They warned that genes from inhaled pollen might transfer into the DNA of bacteria in the respiratory system.73 Although no study has looked into that possibility, pollen from a Bt cornfield appears to have been responsible for allergic-type reactions.
In 2003, during the time when an adjacent Bt cornfield was pollinating, virtually an entire Filipino village of about 100 people was stricken by mysterious skin, respiratory, and intestinal reactions.74 The symptoms started with those living closest to the field and spread to those further away. Blood samples from 39 individuals showed antibodies in response to Bt-toxin, supporting— but not proving—a link. When the same corn was planted in four other villages the following year, however, the symptoms returned in all four areas—only during the time of pollination.75
Bt-toxin might also trigger reactions by skin contact. In 2005, a medical team reported that hundreds of agricultural workers in India are developing allergic symptoms when exposed to Bt cotton, but not when exposed to natural varieties.76 They say reactions come from picking the cotton, cleaning it in factories, loading it onto trucks, or even leaning against it. Their symptoms are virtually identical to those described by the 500 people in Vancouver and Washington who were sprayed with Bt (see table on next page).
GOVERNMENT EVALUATIONS MISS MOST HEALTH PROBLEMS
Although the number of safety studies on GM foods is quite small, it has validated the concerns expressed by FDA scientists and others. Unfortunately, government safety assessments worldwide are not competent to even identify most of the potential health problems described above, let alone protect its citizens from the effects.77
A 2000 review of approved GM crops in Canada by Professor Ann Clark PhD, for example, reveals that 70% (28 of 40) “of the currently available GM crops . . . have not been subjected to any actual lab or animatoxicity testing, either as refined oils for direct human consumption or indirectly as feedstuffs for livestock. The same finding pertains to all three GM tomato decisions, the only GM flax, and to five GM corn crops.” Inthe remaining 30% (12) of the other crops tested, animals were not fed the whole GM feed. They were given just the isolated GM protein that the plant was engineered to produce. But even this protein was not extracted from the actual GM plant. Rather, it was manufactured in genetically engineered bacteria. Thmethod of testing would never identify problems associated with collateral damage to GM plant DNA, unpredicted changes in the GM protein, transfer of genes to bacteria or human cells, excessive herbicidresidues, or accumulation of toxins in the food chain, among others. Clark asks, “Where are the trials showing lack of harm to fed livestock, or that meat and milk from livestock fed on GM feedstuffs are safe?"78
Epidemiologist and GM safety expert Judy Carman, PhD, MPH, shows that assessments by Food Safety Australia New Zealand (FSANZ) also overlook serious potential problems, including cancer, birth defects,long-term effects of nutritional deficiencies. 79
“A review of twelve reports covering twent-eight GM crops -- four soy, theree corn, ten potatoes, eight canola, one sugar beet and two cotton—revealed no feeding trials on people. In addition, one of the GMcorn varieties had gone untested on animals. Some seventeen foods involved testing with only a single oragavage (a type of forced- feeding), with observation for seven to fourteen days, and only of the substance that had been genetically engineered to appear [the GM protein], not the whole food. Such testing assumethat the only new substance that will appear in the food is the one genetically engineered to appear, that theGM plant-produced substance will act in the same manner as the tested substance that was obtained from another source [GM bacteria], and that the substance will create disease within a few days. All are untestedhypotheses and make a mockery of GM proponents’ claims that the risk assessment of GM foods is based onsound science. Furthermore, where the whole food was given to animals to eat, sample sizes were often very low—for example, five to six cows per group for Roundup Ready soy—and they were fed for only four weeks.”80
Dr. Carman points out that GM "experiments used some very unusual animal models for human health, such as chickens, cows, and trout. Some of the measurements taken from these animals are also unusual measures of human health, such as abdominal fat pad weight, total de- boned breast meat yield, and production.” In her examination of the full range of submittals to authorities in Australia and New Zealand,she says that there was no proper evaluation of “biochemistry, immunology, tissue pathology, and gut, liverand kidney function.”81 Writing on behalf of the Public Health Association of Australia, Dr. Carman says, “The effects of feeding people high concentrations of the new protein over tens of years cannot be determined by feeding 20 mice a single oral gavage of a given high concentration of the protein and taking very basic data for 13-14 days.”82
THE FDA’S FAKE SAFETY ASSESSMENTS
Submissions to the US Food and Drug Administraion (FDA) may be worse than in other countries, since the agency doesn’t actually require any data. Their policy says that biotech companies can determine if their owfoods are safe. Anything submitted is voluntary and, according to former Environmental Protection Agency scientist Doug Gurian-Sherman, PhD, “often lack[s] sufficient detail, such as necessary statistical analyses needed for an adequate safety evaluation.” Using Freedom of Information Requests, Dr. Gurian- Sherman analyzed more than a fourth of the data summaries (14 of 53) of GM crops reviewed by the FDA. He says, “The FDA consultation process does not allow the agency to require submission of data, misses obvious errors in company-submitted data summaries, provides insufficient testing guidance, and does not requirsufficiently detailed data to enable the FDA to assure that GE crops are safe to eat.”83 Similarly, a Friends ofthe Earth review of company and FDA documents concluded:
“If industry chooses to submit faulty, unpublishable studies, it does so without consequences. if it should respond to an agency request with deficient data, it does so without reprimand or follow- up. . . . If a company finds it disadvantageous to characterize its product, then its properties remain uncertain or unknown. If a corporation chooses to ignore scientifically sound testing standards . . . then faulty tests are conducted instead, and the results are considered legitimate. In the area of genetically engineered food regulation, the ‘competent’ agencies rarely if ever (know how to) conduct independent research to verify or supplement industry findings.”84
At the end of the consultation, the FDA doesn't actually approve the crops. Rather, they issue a letter that includes a statement such as the following:
"Based on the safety and nutritional assessment that you have conducted, it is our understanding that Monsanto has concluded that corn products derived from this new variety are not materially different in composition, safety, and other relevant parameters from corn currently on the market, and that the genetically modified corn does not raise issues that would require premarket review or approval by FDA. . . . As you are aware, it is Monsanto’s responsibility to ensure that foods marketed by the firm are safe, wholesome and in compliance with all applicable legal and regulatory requirements.”85
COMPANY RESEARCH IS SECRET, INADEQUATE, AND FLAWED
The unpublished industry studies submitted to regulators are typically kept secret based on the claim that it is “confidential business information.” The Royal Society of Canada is one of many organizations that condemn this practice. They wrote:
“In the judgment of the Expert Panel, the more regulatory agencies limit free access to the data upon which their decisions are based, the more compromised becomes the claim that the regulatory process is ‘science based.’ This is due to a simple but well-understood requirement of the scientific method itself—that it be anopen, completely transparent enterprise in which any and all aspects of scientific research are open to full review by scientific peers. Peer review and independent corroboration of research findings are axioms of thscientific method, and part of the very meaning of the objectivity and neutrality of science.”86
Whenever private submissions are made public through lawsuits or Freedom of Information Act Requests, it becomes clear why companies benefit from secrecy. The quality of their research is often miserable, incompetent, and unacceptable for peer-review. In 2000, for example, after the potentially allergenic StarLink corn was found to have contaminated the food supply, the corn’s producer, Aventis CropScienpresented wholly inadequate safety data to the EPA’s scientific advisory panel. One frustrated panel member, Dean Metcalfe, MD,—the government’s top allergist—said during a hearing, “Most of us reva lot of journals. And if this were presented for publication in the journals that I review for, it would be sent back to the authors with all of these questions. It would be rejected.”87
UNSCIENTIFIC ASSUMPTIONS ARE THE BASIS OF APPROVALS
Professor Clark, who analyzed submissions to Canadian regulators, concluded, “Most or all of the conclusions of food safety for individual GM crops are based on inferences and assumptions, rather than on actual testing.” For example, rather than actually testing to see if the amino acid sequence produced by their inserted gene is correct, “the standard practice,” according to research analyst William Freese, “is to sequence just 5 to 25 amino acids,”88 even if the protein has more than 600 in total. If the short sampmatches what is expected, they assume that the rest are also fine. If they are wrong, however, a rearrangprotein could be quite dangerous.
Monsanto’s submission to Australian regulators on their high lysine GM corn provides an excellent example of overly optimistic assumptions used in place of science. The gene inserted into the corn produces a proteinthat is naturally found in soil. Monsanto claimed that since people consume small residues of soil on fruits and vegetables, the protein has a history of safe consumption. Based on the amount of GM corn protein anaverage US citizen would consume (if all their corn were Monsanto’s variety), they would eat up to 4 trillion times the amount normally consumed through soil. In other words, “for equivalent exposure” of the protein from soil “people would have to eat . . . nearly as much as 10,000kg [22,000 pounds], every second 24 hours a day seven days a week.”89
STUDIES ARE RIGGED TO AVOID FINDING PROBLEMS
In addition, to relying on untested assumptions, industry-funded research is often designed specifically to force a conclusion of safety. In the high lysine corn described above, for example, the levels of certain nutritional components (i.e. protein content, total dietary fiber, acid detergent fiber, and neutral deterfiber) were far outside the normal range for corn. Instead of comparing their corn to normal controls, which would reveal this disparity, Monsanto compared it to obscure corn varieties that were also substantially outside the normal range on precisely these values. Thus, their study found no statistical differences -- by design.
When independent researchers published a study in July 1999 showing that GM soy contains 12%-14% less cancer-fighting phytoestrogens, Monsanto responded with its own study, concluding that soy’s phytoestrogen levels vary too much to even carry out a statistical analysis. Researchers failed to disclose, however, that they had instructed the laboratory to use an obsolete method of detection—one that had been prone to highly variable results.90
When Aventis prepared samples to see if the potential allergen in StarLink corn remained intact after cooking, instead of using the standard 30-minute treatment, they heated corn for two hours.91 To show that pasteurization destroyed bovine growth hormone in milk from cows treated wit rbGH, scientists pasteurized the milk 120 times longer than normal. Unable to destroy more than 19%, they then spiked the milk with a huge amount of the hormone and repeated the long pasteurization, destroying 90%.(The FDA reported that pasteurization destroys 90% of the hormone.93)
To demonstrate that injections of rbGH did not interfere with cow’s fertility, Monsanto apparently added cows to the study that were pregnant prior to injection.94
And in order to prove that the protein from their GM crop breaks down quickly during simulated digestion, biotech companies used thousands of times the amount of digestive enzymes and a much stronger acid compared to that recommended by the World Health Organization.95
Other methods used to hide problems are varied and plentiful. For example, researchers: • Use highly variable animal starting weights to hinder detection of food-related changes *Keep feeding studies short to miss long-term impacts been sprayed with Roundup *Avoid feeding animals the actual GM crop, but give them instead a single dose of the GM protein that was produced inside GM bacteria *Use too few subjects to derive statistically significant results •Use poor statistical methods or simply leave out essential methods, data, or statistics • Use irrelevant control groups, and employ insensitive evaluation techniques
ROUNDUP READY SOYBEANS: CASE STUDY OF FLAWED RESEARCH
Monsanto’s 1996 Journal of Nutrition studies on Roundup Ready soybeans96,97 provide plenty ocientific transgressions. Although the study has been used often by the industry as validation for safety claims, experts working in the field were not impressed. For example, Dr. Arpad Pusztai was commissioned at the time by the UK government to lead a member consortium in three institutions to develop rigorous testing protocols on GM foods—protocols that were never implemented. Dr. Pusztai, who had published several studies in that same nutrition journal, said the Monsanto paper was not “up to the normal journal standards.” He said, “It was obvious that the study had been designed to avoid finding any problems. Everybody in our consortium knew this.” Some of the flaws include:
• Researchers tested GM soy on mature animals, not young ones. Young animals use protein to builmuscles, tissues, and organs. Problems with GM food could therefore show up in organ and body weight. But adult animals use the protein for tissue renewal and energy. “With a nutritional study on mature animals," says Dr. Pusztai, “you would never see any difference in organ weights even if the food turned out to be anti-nutritional. The animals would have to be emaciated or poisoned to show anything.”
• If there were an organ development problem, the study wouldn’t have picked it up since the researchers didn’t even weigh the organs.
*In one of the trials, researchers substituted only one tenth of the natural protein with GM soy protein. In two others, they diluted their GM soy six- and twelve-fold. 98 Scientists Ian Pryme, PhD, of Norway and Rolf Lembcke, PhD, of Denmark wrote, the “level of the GM soy was too low, and would probably ensure that any possible undesirable GM effects did not occur.”
• Pryme and Lembcke, who published a paper in Nutrition and Health that analyzed all published peer-reviewed feeding studies on GM foods (10 as of 2003), also pointed out that the percentage of protein in the feed used in the Roundup Ready study was “artificially too high.” This “would almost certainly mask, or at least effectively reduce, any possible effect of the [GM soy].” They said it was “highly likely that GM effects would have been diluted out.” 99
• Proper compositional studies filter out effects of weather or geography by comparing plants grown at the same time in the same location. Monsanto, however, pooled data from several locations, which makes it difficult for differences to be statistically significant. Nonetheless, the data revealed significant differences in the ash, fat, and carbohydrate content. Roundup Ready soy meal also contained 27% more trypsin inhibitor, a potential allergen. Also, cows fed GM soy produced milk with a higher fat content, demonstrating another disparity between the two types of soy.
• One field trial, however, did grow GM and non-GM plants next to each other, but this data was not included in the paper. Years after the study appeared, medical writer Barbara Keeler recovered the data hat had been omitted. It showed that Monsanto’s GM soy had significantly lower levels of protein, fatty acid, and phenylalanine, an essential amino acid. Also, toasted GM soy meal contained nearly twice the amount of a lectin—a substance that may interfere with the body’s ability to assimilate other nutrients. And the amount of trypsin inhibitor in cooked GM soy was as much as seven times higher than in a cooked non-GM control.
• The study also omitted many details normally required for a published paper. According to Pryme and Lembcke, “No data were given for most of the parameters.”
• And when researchers tested the effects of Roundup Ready protein on animals, they didn’t extract the protein from the soybeans. Instead, they derived it from GM bacteria, claiming the two forms of protein were equivalent. There are numerous ways, however, in which the protein in the soy may be different. In fact, nine years after this study was published, another study showed that the gene inserted into the soybeans produced unintended aberrant RNA strands, meaning that the protein may be quite different than what was intended.100
In Pryme and Lembcke’s analysis, it came as no surprise that this Monsanto study, along with the other four peer-reviewed animal feeding studies that were “performed more or less in collaboration with private companies,” reported no negative effects of the GM diet. “On the other hand,” they wrote, “adverse effects were reported (but not explained) in [the five] independent studies.” They added, “It is remarkable that these effects have all been observed after feeding for only 10–14 days.”101
TOXIC GM FOODS COULD HAVE BEEN APPROVED
Two GM foods whose commercialization was stopped because of negative test ref what may be getting through. Rats fed GM potatoes had potentially precancerous cell growth in the stomach and intestines, less developed brains, livers, and testicles, partial atrophy of the liver, and damaged immune systems.102 GM peas provoked an inflammatory response in mice, suggesting that the peas mighttrigger a deadly anaphylactic shock in allergic humans.103 Both of these dangerous crops, however, could easily have been approved. The problems were only discovered because the researchers used advanced testhat were never applied to GM crops already on the market. Both would have passed the normal tests thacompanies typically use to get their products approved.
Ironically, when Monsanto was asked to comment on the pea study, their spokesperson said it demonstratethat the regulatory system works. He failed to disclose th through such rigorous tests.
RAMPANT, UNRELENTING INDUSTRY BIAS
Industry-funded research that favors the funders is not new. Bias has been identified across several industries. In pharmaceuticals, for example, positive results are four times more likely if the drug’s manufacturer funds the study.104 When companies pay for the economic analyses of their own cancer drugs, the results are eight times more likely to be favorable.105 Compared to drug research, the potential for industry manipulation in GM crop studies is considerably higher. Unlike pharmaceutical testing, GM research has no standardized procedures dictated by regulators. GM studies are not usually published in peer-reviewed journals and are typically kept secret by companies and governments. There is little money available for rigorous independent research, so company evidence usually goes unchallenged and unverified. Most importantly, whereas drugs can show serious side-effects and still be approved, GM food cannot. There is no tolerance for adverse reactions; feeding trials must show no problems.
Thus, when industry studies show problems (in spite of their efforts to avoid them), serious adverse reactions and even deaths among GM- fed animals are ignored or dismissed as “not biologically significant” or due to “natural variations.” In the critical arena of food safety research, the biotech industry is without countability, standards, or peer-review. They’ve got bad cience down to a science.
PROMOTING AND REGULATING DON’T MIX
While such self-serving behavior may be expected from corporations, how come government bodies let such blatant scientific contortions pass without comment? One reason is that several regulatory agencies are also charged with promoting the interests of biotechnology. This is the official position of the FDA and other US government bodies, for example. Suzanne Wuerthele, PhD, a US EPA toxicologist, says, “This technology is being promoted, in the face of concerns by respectable scientists and in the face of data to the contrary, by the very agencies which are supposed to be protecting human health and the environment. The bottom line in my view is that we are confronted with the most powerful technology the world has ever known, and it is being rapidly deployed with almost no thought whatsoever to its consequences.”
Canadian regulators are similarly conflicted. The Royal Society of Canada reported that, “In meetings with senior managers from the various Canadian regulatory departments . . . their responses uniformly stressed the importance of maintaining a favorable climate for the biotechnology industry to develop new products and submit them for approval on the Canadian market. . . . The conflict of interest involved in both promoting and regulating an industry or technology . . . is also a factor in the issue of maintaining the transparency, and therefore the scientific integrity, of the regulatory process. In effect, the public interest in a regulatory system that is ‘science based’. . . is significantly compromised when that openness is negotiated away by regulators in exchange for cordial and supportive relationships with the industries being regulated.”106
Many scientists on the European Food Safety Authority (EFSA) GMO Panel are personally aligned with biotech interests. According to Friends of the Earth (FOE), “One member has direct financial links with the biotech industry and others have indirect links, such as close involvement with major conferences organized by the biotech industry. Two members have even appeared in promotional videos produced by the biotech industry. . . . Several members of the Panel, including the chair Professor Kuiper, have been involved with the EU- funded ENTRANSFOOD project. The aim of this project was to agree [to] safety assessment, risk management, and risk communication procedures that would ‘facilitate market introduction of GMOs in Europe, and therefore bring the European industry in a competitive position.’ Professor Kuiper, who coordinated the ENTRANSFOOD project, sat on a working group that also included staff from Monsanto, Bayer CropScience, and Syngenta.” In a statement reminiscent of the deceptive policy statement by the FDA, the FOE report concludes that EFSA is “being used to create a false impression of scientific agreement when the real situation is one of intense and continuing debate and uncertainty.”107
The pro-GM European Commission repeats the same ruse. According to leaked documents obtained by FOE, while they privately appreciate “the uncertainties and gaps in knowledge that exist in relation to the safety of GM crops, . . . the Commission normally keeps this uncertainty concealed from the public whilst presenting its decisions about the safety of GM crops and foods as being certain and scientifically based.” For example, the Commission privately condemned the submission information for one crop as “mixed, scarce, delivered consecutively all over years, and not convincing.” They said there is “No sufficient experimental evidence to assess the safety.”108
With an agenda to promote GM foods, regulators regularly violate their own laws. In Europe, the law requires that when EFSA and member states have different opinions, they “are obliged to co-operate with a view to either resolving the divergence or preparing a joint document clarifying the contentious scientific issues and identifying the relevant uncertainties in the data.”109 According to FOE, in the case of all GM crop reviews, none of these legal obligations were followed.110 The declaration of GRAS status by the FDA also deviated from the Food and Cosmetic Act and years of legal precedent. Some violations are more blatant. In India, one official tampered with the report on Bt cotton to increase the yield figures to favor Monsanto. 111 In Mexico, a senior government official allegedly threatened a University of California professor, implying “We know where your children go to school,” trying to get him not to publish incriminating evidence that would delay GM approvals.112 In Indonesia, Monsanto gave bribes and questionable payments to at least 140 cials, attempting to get their genetically modified (GM) ctton approved.113
MANIPULATION OF PUBLIC OPINION
When governments fail in their duty to keep corporations in check, the “protector” role should shift to the media, which acts as a watchdog to expose public dangers and governmental shortcomings. But mainstream media around the world has largely overlooked the serious problems associated with GM crops and their regulation. The reason for this oversight is varied and includes contributions from an aggressive public relations and disinformation campaign by the biotech industry, legal threats by biotech companies, and in some cases, the fear of losing advertising accounts. This last reason is particularly prevalent among the farm press, which receives much of its income from the biotech industry. Threatening letters from Monsanto’s attorneys have resulted in the cancellation of a five-part news series on their genetically engineered bovine growth hormone scheduled for a Fox TV station in Florida, as well as the cancellation of a book critical of Monsanto’s GMO products. A printer also shredded 14,000 copies of the Ecologist magazine issue entitled “The Monsanto Files,” due to fear of a Monsanto lawsuit. (See the chapter “Muscling the Media” in Seeds of Deception114 for more examples.)
The methods that biotech advocates use to manipulate public opinion research has become an art form. Consumer surveys by the International Food Information Council (IFIC), for example,whose supporters include the major biotech seed companies, offers conclusions such as “A growing majority of Americans support the benefits of food biotechnology as well as the US Food and Drug Administration’s (FDA) labeling policy.” But communications professor James Beniger, who was past president of the American Association for Public Opinion Research, described the surveys as “so biased with leading questions favoring positive responses that any results are meaningless.”115 The 2003 survey, for example, included gems such as:
“All things being equal, how likely would you be to buy a variety of produce, like tomatoes or potatoes, if it had been modified by biotechnology to taste better or fresher?” and “Biotechnology has also been used to enhance plants that yield foods like cooking oils. If cooking oil with reduced saturated fat made from these new plants was available, what effect would the use of biotechnology have on your decision to buy this cooking oil?”116
A similar tactic was used at a December 11, 2007 focus group in Columbus, Ohio “designed” to show that consumers wanted to make it illegal for dairies to label their milk as free from Monsanto’s genetically engineered bovine hormone rBST. The facilitator said, “All milk contains hormones. There is no such thing as hormone- free milk. The composition of both types of milk is the same in all aspects. Now what do you think of a label that says ‘no added hormones?’ Don’t you think it is deceiving and inappropriate to put ‘rBST-free’ on labels?” Not only was the facilitator “leading the witness,” he presented false information. Milk from cows treated with rBST has substantially higher levels of Insulin- like Growth Factor-1,117 which has been linked to higher risk of cancer,118 and higher incidence of fraternal twins.119 It also has higher levels of bovine growth hormone, pus, and in some cases, antibiotics.
Another example of manipulated consumer opinion was found in a 2004 article in the British Food Journal, authored by four advocates of genetically modified (GM) foods.120 According to the peer-reviewed paper, when shoppers in a Canadian farm store were confronted with an informed and unbiased choice between GM corn and non-GM corn, most purchased the GM variety. This finding flew in the face of worldwide consumer resistance to GM foods, which had shut markets in Europe, Japan, and elsewhere. It also challenged studies that showed that the more information on genetically modified organisms (GMOs) consumers have, the less they trust them.121 The study, which was funded by the biotech-industry front group, Council for Biotechnology Information and the industry’s trade association, the Crop Protection Institute of Canada (now Croplife Canada), was given the Journal’s prestigious Award for Excellence for the Most Outstanding Paper of 2004 and has been cited often by biotech advocates.
Stuart Laidlaw, a reporter from Canada’s Toronto Star, visited the farm store several times during the study and described the scenario in his book Secret Ingredients. Far from offering unbiased choices, key elements appeared rigged to favor GM corn purchases. The consumer education fact sheets were entirely pro-GMO, and Doug Powell, the lead researcher, enthusiastically demonstrated to Laidlaw how he could convince shoppers to buy the GM varieties. He confronted a farmer who had already purchased non-GM corn. After pitching his case for GMOs, Powell proudly had the farmer tell Laidlaw that he had changed his opinion and would buy GM corn in his next shopping trip.
Powell’s interference with shoppers’ “unbiased” choices was nothing compared to the effect of the signs placed over the corn bins. The sign above the non-GM corn read, “Would you eat wormy sweet corn?” It further listed the chemicals that were sprayed during the season. By contrast, the sign above the GM corn stated, “Here’s What Went into Producing Quality Sweet Corn.” It is no wonder that 60% of shoppers avoided the “wormy corn.” In fact, it may be a testament to people’s distrust of GMOs that 40% still went for the “wormy” option.
Powell and his colleagues did not mention the controversial signage in their study. They claimed that the corn bins in the farm store were “fully labelled”—either “genetically engineered Bt sweet corn” or “Regular sweet-corn.” When Laidlaw’s book came out, however, Powell’s “wormy” sign was featured in a photograph,122 exposing what was later described by Cambridge University’s Dr. Richard Jennings as “flagrant fraud.” Jennings, who is a leading researcher on scientific ethics, says, “It was a sin of omission by failing to divulge information which quite clearly should have been disclosed.”123
In his defence, Powell claimed that his signs merely used the language of consumers and was “not intended to manipulate consumer purchasing patterns.” He also claimed that the “wormy” corn sign was only there for the first week of the trial and was then replaced by other educational messages. But eye witnesses and photographs demonstrate the presence of the sign long after Powell’s suggested date of replacement.124
Several scientists and outraged citizens say the paper should be withdrawn, but the Journal refused. In fact, the Journal’s editor has not even agreed to reconsider its Award for Excellence. A blatant propaganda exercise still stands validated as exemplary science.
CRITICS AND INDEPENDENT SCIENTISTS ARE ATTACKED
One of the most troubling aspects of the biotech debate is the attack strategy used on GMO critics and independent scientists. Not only are adverse findings by independent scientists often suppressed, ignored, or denied, researchers that discover problems from GM foods have been fired, stripped of responsibilities, deprived of tenure, and even threatened. Consider Dr. Pusztai, the world’s leading scientist in his field, who inadvertently discovered in 1998 that unpredictable changes in GM crops caused massive damage in rats. He went public with his concerns, was a hero at his prestigious institute for two days, and then, after the director received two phone calls allegedly from the UK Prime Minister’s office, was fired after 35 years and silenced with threats of a lawsuit. False statements were circulated to trash his reputation, which are recited by GMO advocates today.
After University of California Professor Ignacio Chapela, PhD, published evidence that GM corn contaminated Mexico’s indigenous varieties, two fictitious internet characters created by Monsanto’s PR firm, the Bivings Group, initiated a brutal internet smear campaign, lying about Dr. Chapela and his research.
Irina Ermakova, PhD, a leading scientist at the Russian National Academy of Sciences, fed female rats GM soy and was stunned to discover that more than half their offspring died within three weeks— compared to only 10% from mothers fed non-GM soy. Without funding to extend her analysis, she labeled her work “preliminary,” published it in a Russian journal, and implored the scientific community to repeat the study. Two years later, no one has repeated it, but advocates use false or irrelevant arguments to divert attention from the shocking results and have tried to vilify Dr. Ermakova.
A New Zealand MP testified at the 2001 Royal Commission of Inquiry on Genetic Modification, “I have been contacted by telephone and e- mail by a number of scientists who have serious concerns . . . but who are convinced that if they express these fears publicly. . . or even if they asked the awkward and difficult questions, they will be eased out of their institution.” Indeed this year, after Professor Christian Velot, PhD, raised the difficult questions on GMOs at public conferences, his 2008 research funds were confiscated, his student assistants were re-assigned, andis position at the University of Paris-Sud faces early termination.
WE’RE THE GUINEA PIGS
Since GM foods are not properly tested before they enter the market, consumers are the guinea pigs. But this doesn’t even qualify as an experiment. There are no controls and no monitoring. Given the mounting of evidence of harm, it is likely that GM foods are contributing to the deterioration of health in the United States, Canada, and other countries where it is consumed. But without post- marketing surveillance, the chances of tracing health problems to GM food are low. The incidence of a disease would have to increase dramatically before it was noticed, meaning that millions may have to get sick before a change is investigated. Tracking the impact of GM foods is even more difficult in North America, where the foods are not labeled.
Regulators at Health Canada announced in 2002 that they would monitor Canadians for health problems from eating GM foods. A spokesperson said, “I think it’s just prudent and what the public expects, that we will keep a careful eye on the health of Canadians.” But according to CBC TV news, Health Canada “abandoned that research less than a year later saying it was ‘too difficult to put an effective surveillance system in place.’” The news anchor added, “So at this point, there is little research into the health effects of genetically modified food. So will we ever know for sure if it’s safe?”125
Not with the biotech companies in charge. Consider the following statement in a report submitted to county officials in California by pro-GM members of a task force. “[It is] generally agreed that long-term monitoring of the human health risks of GM food through epidemiological studies is not necessary because there is no scientific evidence suggesting any long-term harm from these foods.”126 Note the circular logic: Because no long-term epidemiological studies are in place, we have no evidence showing long-term harm. And since we don’t have any evidence of long- term harm, we don’t need studies to look for it.
What are these people thinking? Insight into the pro-GM mindset was provided by Dan Glickman, the US Secretary of Agriculture under President Clinton.
“What I saw generically on the pro-biotech side was the attitude that the technology was good, and that it was almost immoral to say that it wasn’t good, because it was going to solve the problems of the human race and feed the hungry and clothe the naked. . . . And there was a lot of money that had been invested in this, and if you’re against it, you’re Luddites, you’re stupid. That, frankly, was the side our government was on. Without thinking, we had basically taken this issue as a trade issue and they, whoever ‘they’ were, wanted to keep our product out of their market. And they were foolish, or stupid, and didn’t have an effective regulatory system. There was rhetoric like that even here in this department. You felt like you were almost an alien, disloyal, by trying to present an open-minded view on some of the issues being raised. So I pretty much spouted the rhetoric that everybody else around here spouted; it was written into my speeches.”127
Fortunately, not everyone feels that questioning GM foods is disloyal. On the contrary, millions of people around the world are unwilling to participate in this uncontrolled experiment. They refuse to eat GM foods. Manufacturers in Europe and Japan have committed to avoid using GM ingredients. And the US natural foods industry, not waiting for the government to test or label GMOs, is now engaged in removing all remaining GM ingredients from their sector using a third party verification system. The Campaign for Healthier Eating in America will circulate non-GMO shopping guides in stores nationwide so that consumers have clear, healthy non-GMO choices. With no governmental regulation of biotech corporations, it is left to consumers to protect ourselves.
