GM Free Cymru has been campaigning for years against the decline
in ethical standards in GM science, linked in part to the rise in corporate
control over the research agenda, and in part to feeble regulatory bodies that
place the “politics
of convenience” and commercial interests above scientific integrity and
respect for the truth.
This is an extract from an article by Jeffrey Smith, in which he exposes some
of the common practices of those who have set themselves the goal of demonstrating
that GM crops and foods are safe and environmentally harmless – come
hell or high water.
---------------------------------
THE UNPUBLISHED INDUSTRY STUDIES SUBMITTED TO REGULATORS ARE TYPICALLY KEPT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 AN OPEN, 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
THE SCIENTIFIC METHOD, AND PART OF THE VERY MEANING OF THE OBJECTIVITY AND
NEUTRALITY OF SCIENCE.' [7]
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 discovered in the food supply, Aventis CropScience presented 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 review for a 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.' [8]
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 - overseen by Monsanto;s former attorney who later became the
company's vice president - says that biotech companies can determine if their
own foods are safe. Anything submitted is voluntary and, according to former
Environmental Protection Agency scientist Doug Gurian-Sherman, 'often lack[s]
sufficient detail, such as necessary statistical analyses needed for an adequate
safety evaluation.' Using Freedom of Information Requests, Gurian-Sherman analyzed
more than a fourth of the data summaries (14 of 53) of GM crops reviewed by
the FDA. He says, 'Our evaluation found that the biotechnology companies provide
inadequate data to ensure their products are safe.' [9]
'Most or all of the conclusions of food safety for individual GM crops are
based on inferences and assumptions, rather than on actual testing,' says Professor
E. Ann Clark, who analyzed submissions to Canadian regulators. 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, even if the
protein has more than 600 in total. If the short sample matches what is expected,
they assume that the rest are also fine. If they are wrong, however, a rearranged
protein could be quite dangerous.'
Monsanto's submission to Australian regulators on their high lysine GM corn
provides several examples of optimistic assumptions used in place of science.
The GM protein produced in the corn is also found in soil. The company claimed
that since people consume small residues of soil on fruits and vegetables,
the protein has a history of safe consumption. An independent calculation by
the Centre for Integrated Research on Biosafety (INBI), however, reveals the
weakness of this argument. Based on the amount of GM corn protein an average
US citizen would consume (if all their corn were Monsanto's variety), 'for
equivalent exposure' of the protein from soil 'people would have to eat between
80-800 million (males) or 60-700 million (females) kilograms of soil each day,
or nearly as much as 10,000kg/second 24 hours a day seven days a week.' INBI
estimated that the normal exposure to the protein from soil residues was actually
'about 30 billion-4 trillion times less than exposure through [high lysine]
corn.' [10]
In addition, certain nutritional components of this GM variety (i.e. protein
content, total dietary fiber, acid detergent fiber, and neutral detergent fiber)
lie 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.
Epidemiologist Judy 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 milk
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, liver and kidney function.'
[11] Writing on behalf of the Public Health Association of Australia, 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 . . .The acute toxicity testing proposed as adequate would simply
not pick up cancer, teratology [birth defects] or the long-tem effects of nutrient
deficiencies or increases in anti-nutrients.' [12]
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. [13]
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.
TO SHOW THAT PASTEURIZATION DESTROYED BOVINE GROWTH HORMONE IN MILK FROM COWS
TREATED WITH RBGH, THEY 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.)
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.
AND IN ORDER TO PROVE THAT THE PROTEIN FROM THEIR GM CROPS 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.
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
*TEST EFFECTS OF ROUNDUP READY SOYBEANS THAT HAVE NOT 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 RIGGED OR IRRELEVANT CONTROL GROUPS, AND EMPLOY INSENSITIVE OR OBSOLETE
EVALUATION TECHNIQUES
Monsanto’s 1996 Journal of Nutrition study [14] , [15] provides plenty
of examples of scientific transgressions. Roundup Ready soybeans are engineered
to withstand the normally fatal effects of Monsanto’s herbicide called
Roundup. Monsanto scientists published a feeding study that purported to test
their soybeans’ effect on rats, catfish, chickens, and cows. The study
has been used often by the industry as validation for safety claims. According
to Dr. Arpad Pusztai, however, 'It was obvious that the study had been designed
to avoid finding any problems. Everybody in our consortium knew this.' Pusztai
was commissioned at the time by the UK government to develop rigorous testing
protocols on GM foods—protocols that were never implemented. Pusztai,
who had published several studies in that same nutrition journal, said the
Monsanto paper was 'not really up to the normal journal standards.' Pusztai
says that if he had been asked to referee the paper for publication, 'it would
never have passed.' He's confident that even his graduate assistants would
have taken the study apart in short order. Some of the flaws include:
Researchers tested GM soy on mature animals, not young ones. Young animals
use protein to build their muscles, 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 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.'
Even if there were an organ development problem, the study wouldn’t have
picked it up since the researchers didn’t 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. [16] Scientists Ian Pryme of Norway and Rolf Lembcke 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 peer-reviewed feeding studies on GM foods 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 all GM effects would have been diluted out.' [17]
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, which might
explain the sudden jump in soy allergies in the UK beginning right after Roundup
Ready soy was introduced. 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 discovered the data that had been omitted. It
showed that Monsanto’s GM soy had significantly lower levels of protein,
a fatty acid, and phenylalanine, an essential amino acid. Also, toasted GM
soy meal contained nearly twice the amount of a lectin - one 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
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. [18]
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.' [19]
Two GM foods whose commercialization was stopped because of negative test
results give a chilling example of 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. [20] GM peas provoked an inflammatory response
in mice, suggesting that the peas might trigger a deadly anaphylactic shock
in allergic humans. [21] Both of these dangerous crops, however, could easily
have been approved. The problems were only discovered because the researchers
used advanced tests that were never applied to GM crops already on the market.
Both would have passed the normal tests that companies typically use to get
their products approved.
Ironically, when Monsanto was asked to comment on the pea study, their spokesperson
said it demonstrated that the regulatory system works. He failed to disclose
that none of the company’s GM crops had been put 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. [22] When companies pay for the economic analyses of their own cancer
drugs, the results are eight times more likely to be favorable. [23] 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.'
Numerous reports including peer-reviewed articles and part 3 of the book Genetic
Roulette are replete with examples of rigged research. But making these public
does not seem to curtail its practice. Consider the wormy corn of the British
Food Journal. Not only has the editor refused to retract the paper, he has
not even agreed to reconsider its Award for Excellence. A blatant propaganda
exercise still stands validated as exemplary science.
In the critical arena of food safety research, where the health of society
is caught in the balance, it is entirely unacceptable that the biotech industry
is without accountability, standards, or peer-review. At our expense, they’ve
got bad science down to a science.
