SECRET
MONSANTO GM POTATO STUDY SUPPRESSED FOR 8 YEARS
GM Potatoes are "unfit for
human consumption"
A secret feeding study of Monsanto GM potatoes, conducted in 1998 by
the Institute of Nutrition of the Russian Academy of Medical Sciences and
suppressed for 8 years, showed that the potatoes did considerable damage
to the organs of the rats in the study (1) (2). In comparison the rats in
the "control groups" which were fed on normal potatoes or on a
non-potato diet were healthier, and had much less organ and tissue damage.
This research, fully supported by Monsanto through the provision of the GM
potatoes, was conducted at approximately the same time as Arpad Pusztai's
research in the Rowett Institute.
The potatoes used in the study were Monsanto GM NewLeaf potatoes bred
in 1995 from the Russet Burbank variety to be resistant to the Colorado
Beetle. The GM event was registered as 082, and the potatoes are included
in the Bt group of GM crops. They also contain an antibiotic resistance
marker gene (3). The potatoes were deregulated in the USA in 1998, without
any feeding studies being required. Another line was deregulated in 1999.
Even earlier, in 1996, Monsanto started to introduce the potatoes into
Russia and Georgia, and probably into many other countries with lax
approval regimes as well (4). For some reason (probably to assist in the
consent process) Monsanto co-operated in some feeding studies involving
rats from the Institute of Nutrition of the Russian Academy of Medical
Sciences. Something "inconvenient" showed up in these feeding
studies, but the Institute refused to release all the information into the
public domain and in 1999 the researchers presented a "doctored"
version of their Report in support of Monsanto's application for Russian
commercialization. The consent was duly given in 2000 by the Russian
regulators on the basis of this corrupt piece of science.
However, Greenpeace and other consumer groups mounted a protracted and
immensely frustrating campaign to obtain a sight of the feeding study
Report. In May 2004 the Nikulinski District Court in Russia ruled that
information relating to the safety of GM food should be open to the
public. On the basis of this ruling Greenpeace tried to obtain the GM
potato report; but the Institute and Monsanto refused to release it. So
Greenpeace and local activist groups again took the Institute to court,
and in October 2005 won a ruling that the Report must be released. At last
it was handed over, and examined by Dr Irina Ermakova at the request of
Greenpeace. She produced a brief Russian paper on her findings, and we
have now produced an English- language version with the kind agreement of
Greenpeace (5).
Ironically, the NewLeaf GM potato was a failure, and it proved to give
poor yields and to be susceptible to disease in European environments.
While Monsanto was enthusiastically promoting its GM potatoes in Eastern
Europe, it was having second thoughts in the United States and Western
Europe, and pulled out of GM potato development in 2002 (6). The results
of the 1998 GM potato rat feeding study may well have had a bearing on
that decision.
Dr Irina Ermakova, the Greenpeace consultant, has herself conducted
animal feeding experiments with GM materials. In her very restrained
commentary on the Russian study (1) she criticized the small scale of the
experiment and its design, and was especially critical of the complacent
conclusions drawn by the authors from evidence which was actually
profoundly worrying. The GM potato was nutritionally inferior to its
conventional counterpart and to other Russian potato varieties. The
research results showed that both "normal" Russet Burbank
potatoes and the GM variety caused "serious morphological changes in
the internal organs" of the animals in the trials. They also showed
that the group of animals fed on the GM potatoes suffered greater weight
loss than the other animals, and statistically significantly greater
damage to kidneys, liver and large gut. There was also greater damage to
blood serum, testes and prostate. Dr Ermakova concluded: "The GM
potatoes were the most dangerous of the feeds used in the trials........
and on the basis of this evidence they CANNOT be used in the nourishment
of people."
Given the small scale of the feeding trials (only ten animals in each
feeding group) and doubts about the statistical significance of some of
the Report's findings, Dr Ermakova stressed the importance of follow-up
studies on a larger scale and with more careful experimental design. But
no matter what the shortcomings of the work may be, the Institute of
Nutrition research did nothing to show that the Monsanto GM potatoes are
safe. That should not be a surprise to anybody, since Bt potatoes are
classified as pesticides in the US and have never been tested for toxicity
or allergenicity (7).
According to Dr Brian John of GM Free Cymru, it is incredible that
Monsanto and the Institute of Nutrition have kept the research secret
until now. "That obsessive secrecy has clearly been against the
public interest," he says, "and it tells us a great deal about
Monsanto's priorities. If the company had any regard at all for the health
of consumers, it would have published these results world-wide in 1999,
and at the very least it would have commissioned follow-up research which
might have confirmed or discredited the study's findings. Instead of that,
it connived with the Russian researchers to keep the information away from
public scrutiny, just as it did with the feeding study results for MON863
maize in 2005. On that occasion too, it took a court case and massive
media coverage to obtain sight of the research team's raw data and to
reveal evidence of damage to health." (8)
While Monsanto attempted to suppress the information from the 1998
Russian study, it connived in the vilification of Dr Arpad Pusztai, a
respectable and careful scientist whose findings were very similar (9)
(10). The company must have known that the release of its own feeding
study information would have supported his findings and would have
contributed to a general understanding on health concerns specific to GM
potatoes. "The actions of Monsanto in this case have been utterly
reprehensible," says Dr John. "The company has continued to
promote its GM potatoes as perfectly harmless, while for eight years it
has managed to keep out of the public domain clear evidence that they are
harmful to animals and hence to human beings also. And it has got away
with it because the science establishment and the GM regulators within the
EU -- as in Russia -- cannot see scientific corruption when it is staring
them in the face." (11)
