GM Corn Shortens Lives of Study Rats

Posted on 10 October 2012 by Jerry

[Update: Two French scientific organizations have criticized this study as reported in the October 26, 2012 issue of Science magazine.  The French High Council of Biotechnology and the Agency for Food, Environmental and Occupational Health & Safety have both labelled the study referenced in this post as “inconclusive due to methodological, statistical, and interpretative limitations.”  The French government has nevertheless has said it will suggest new European procedures for evaluation, approval, and control of GM organisms.  The government stated this decision was independent of the study findings.]

As could be expected, a new study linking higher numbers of cancers, bigger tumors and earlier deaths of research rats fed Monsanto’s genetically modified corn (NK603) for most of their lives, has created considerable controversy.  The corn, NK603, is widely sold for human and animal consumption in the United States and Canada. A research study published in the peer reviewed journal of Food and Toxicology is the first study to look at the effects of longer term consumption of corn modified to resist the effects of Monsanto’s Roundup, the herbicide glyphosate.

The study rats were fed the GM corn for two years or almost their entire lifetimes.  All earlier studies were no longer than the 90 days required by the U.S. Food and Drug Administration and other regulatory bodies.  Once again we see the money and power of the chemical industry as it marshals its resources and the research community it supports to immediately attack the validity of the research findings. We also see the embarrassment of regulatory bodies seeking to defend their earlier superficial studies.

Giles-Eric Séralini, a molecular biologist at University of Caen, France and Joël Spiroux de Vendômois, president of CRIIGEN, co-authors of the study were reportedly “Surprised by the ‘violence’ and immediacy of scientists’ criticisms.  They argue that most of the critics are not toxicologists, and suggest that some may have competing interests, including working to develop transgenic crops.” José Domingo stated the study passed the peer review and raised no red flags at the journal of Food and Toxicology.  Dr Domingo is a toxicologist at Rovira I Vigili University in Reus, Spain, and managing editor of the journal.

Giles-Eric Séralini has been subjected to much criticism from the genetic engineering and chemical communities.  In 2011, in response to public insults, Seralini sued Marc Fellows, president of the French Association of Plant Biotechnology, for defamation and won.  He continues to be quite controversial because of his open stand against genetically modified foods.  Detractors argue it is he that has ulterior motives for releasing this study.

Even with all the immediate criticism of the study, its results cannot be ignored.  Fortunately for the French, their Prime Minister Jean-Mark Ayrault, said that, if the results are confirmed, the government will press for a Europe-wide ban on the genetically modified crop.  U. S. citizens should not look for the U.S. government to call for additional, longer term studies of the negative effects of this GM corn.  

As reported earlier in this blog, see the June 13, 2012 article “Genetic Engineering Influence Peddling and Profit”, support for genetic engineering is explicitly sponsored by the U.S. government. The post states, “Among the many WikiLeaks disclosed cables from within the State Department are a number of cables that reveal the full and explicit U.S. government support for the U.S. chemical and agriculture business’ genetically modified foods.  It is particularly instructive to learn that the strategic policy of the United States is to support and promulgate genetically modified foods.

It is no coincidence that there is significant resistance to genetically modified foods in the French government.  The French government was under assault at many levels by the U.S. government and chemical companies attempting to force them to change their negative position on GM crops.  As shown by WikiLeaks cables reported on in the Atlantic Monthly (see last link below), the U.S. government threatened a “trade war” in retaliation if France didn’t reverse its anti-GM stance.

See additional blog posts, the April 27, 2012 article “Roundup (Glyphosate) and Infertility” and the October 27, 2011 article “Where there’s toxins, there’s….WHAT?” Each article documents different studies pointing to the potential negative effects of human and animal consumption of Monsanto’s genetically modified, Roundup Ready crops (including the GM corn referenced above).

The question posed is when will citizens of the world say enough is enough?  The war over genetically modified, Roundup Ready, crops is reminiscent of the “stonewall” techniques of the tobacco industry in the U.S.  Just consider the decades of debate and hidden studies and documents in the tobacco company’s files that only became public in the last decade, and still cigarettes are sold around the world and in the U.S.  Let us hope that at least a small step of mandatory labeling of genetically modified foods is passed in California in the upcoming election.  This may be the last, best chance the U.S. citizen has to make progress on this issue.
