The Institute for Responsible Technology, an organization opposed to crop biotechnology, has published a list of reasons to avoid GMOs—that is, genetically modified food. It’s a mish-mash of misinformation and disinformation. All of the institute’s assertions are unfounded, but here are the five most dubious claims on the list.
1. GMOs Are Unhealthy
Every independent scientific body that has ever evaluated the safety of biotech crops has found them to be safe for humans to eat.
report from the National Academy of Sciences (NAS) concluded that “no adverse health effects attributed to genetic engineering have been documented in the human population.” In 2003 the International Council for Science, representing 111 national academies of science and 29 scientific unions, found “no evidence of any ill effects from the consumption of foods containing genetically modified ingredients.” The World Health Organization flatly states, “No effects on human health have been shown as a result of the consumption of such foods by the general population in the countries where they have been approved.”A 2004
In 2010, a European Commission review of 50 studies on the safety of biotech crops found “no scientific evidence associating GMOs with higher risks for the environment or for food and feed safety than conventional plants and organisms.” At its annual meeting in June, the American Medical Association endorsed a report on the labeling of bioengineered foods from its Council on Science and Public Health. The report concluded that “Bioengineered foods have been consumed for close to 20 years, and during that time, no overt consequences on human health have been reported and/or substantiated in the peer-reviewed literature.”
Unfortunately there is no shortage of fringe scientists to gin up bogus studies suggesting that biotech crops are not safe. My personal favorite in this genre is Russian researcher Irina Ermakova’s claim, unpublished in any peer-reviewed scientific journal, that eating biotech soybeans turned mouse testicles blue.
One widely publicized specious study (also cited by the IRT) was done by the French researcher Gilles-Eric Seralini and his colleagues. They reported that rats fed pesticide resistant corn died of mammary tumors and liver diseases. Seralini is the president of the scientific council of the Committee for Research and Independent Information on Genetic Engineering, which describes itself as an “independent non-profit organization of scientific counter-expertise to study GMOs, pesticides and impacts of pollutants on health and environment, and to develop non polluting alternatives.” The Committee clearly knows in advance what its researchers will find with regard to the health risks of biotech crops. But when truly independent groups, such as the European Society of Toxicologic Pathology and the French Society of Toxicologic Pathology, reviewed Seralini’s study, they found it essentially to be meretricious rubbish. Six French academies of science issued a statement declaring that the journal should never have published such a low-quality study and excoriating Seralini for orchestrating a media campaign in advance of publication. The European Food Safety Agency’s review of the Seralini study “found [it] to be inadequately designed, analysed and reported.”
Sadly, such junk science has real-world consequences, since Seralini’s article was apparently cited when Kenya made the decision to ban the importation of foods made with biotech crops.
