Gilles-Eric Séralini is a professor of molecular biology at the Institute of Fundamental and Applied Biology (IBFA) of the University of Caen in France. He is also President of the Scientific Board at CRIIGEN.[1] He was fairly well known in the biotech community for having a history of flawed studies,[2][3] but his controversial 2012 study on transgenic NK603 maize made him immensely popular among the anti-GM communities.

[edit] "GMO causes liver and kidney damage" study re-analyses

In 2006, Monsanto published a rat study showing that its YieldGuard® GM corn (MON863) was as safe and nutritious as non-GM corn.[4] Séralini disagreed, and performed his own analysis on the same data Monsanto published. He concluded that Monsanto were a bunch of dirty stinky evil corporate liars, and that the data suggested that MON863 corn caused liver and kidney damage in the rats. Greenpeace enthusiastically agreed.[5]

An expert panel examined Séralini's reanalysis, and decided that he was huffing a heap of hot air.[6] This didn't keep Fox News from reporting Séralini's analysis as a "bombshell" against the GMO industry, over six years later.[7]

[edit] …And again

In 2009, Seralini published another study which re-analyzed the toxicity data for the NK603, MON 810, and MON 863 strains, and — surprise surprise — came to the conclusion that they cause kidney and liver damage.[8] The European Food Safety Authority,[9] the French High Council of Biotechnologies, Scientific Committee[10] and Food Standards Australia New Zealand[11] all had about as many bad things to say about this study as they did about his 2007 study.

[edit] …And again

In 2011, Séralini did something similar with the results of 19 animal studies on GM corn and soybeans.[12] Since this study didn't receive the same degree of criticism as his 2007 and 2009 studies (probably because in light of the quality of Séralini previous output, no one was willing to waste their time), we can all safely conclude that it's 100% well-performed science and must be immediately embraced.Do You Believe That?

[edit] "GMO causes cancer" study

In 2012, Séralini published a study purporting to document that rats fed glyphosate-resistant genetically modified NK603 maize (corn) and/or glyphosate developed cancer at unusually high rates.[13] Soon after publication, numerous news sites posted articles using the study as "proof" that genetically modified foods were dangerous or caused cancer. Many scientists sent letters to the editor demanding retraction of the study for having extremely poor study design,[14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] but the journal who published it didn't ask Seralini to withdraw the paper until late in 2013.[30] Orac of Respectful Insolence[31] was among many bloggers and news sites that posted articles that criticized Séralini's study. Séralini refused to provide data on the amount of food he fed to the rats and their growth rates (refusing to disclose data from a scientific study is a red flag that there's a serious problem with the study),[32] a standard practice that allows independent scientists to verify that the data supports the conclusions drawn by the study. The French academies of Agriculture, Medicine, Pharmacy, Science, Technology, and Veterinary Science all condemned the study as a "scientific non-event."[33] The EFSA,[34] the French Agency for Food, Environmental and Occupational Health & Safety (ANSES),[35] Health Canada,[36] Food Standards Australia New Zealand,[37] Germany's Bundesinstitut für Risikobewertung,[38] Belgium's VIB,[39] Mexico's CIBIOGEM,[40] and several other notable government agencies and research institutes have also condemned the study.

Séralini responded to a handful of criticisms,[41] but he did not release his raw data and refused to answer many major questions. The EFSA reviewed his response and concluded that "it provided only a limited amount of relevant information which failed to address the majority of the outstanding questions raised in the Authority’s first statement."[42] Many conspiracy and anti-GM websites accused all scientists who criticized Séralini's study of being paid by Monsanto; however, none of these accusers have produced any evidence of bribing, and the one letter to the editor from Monsanto scientists contains proper disclosure of their conflict of interest.[43]

In November of 2013, the journal that published Séralini's study retracted it.[44][45] The next day, Séralini threatened to sue the journal.[46] A Huffington Post article said it was "anti-science behavior" to retract the article.[47] The study was republished in June 2014 in Environmental Sciences Europe, an open access journal whose standards are, shall we say, somewhat more lenient.[48]

[edit] CRIIGEN

CRIIGEN, the institute behind Séralini's study, has some worrying issues. Their current president is a homeopath/acupuncturist,[49] and several articles have found financial connections to the French supermarkets Auchan and Carrefour.[50] Carrefour launched an advertising campaign for their GM-free product range a mere five days after Séralini's study was published. CRIIGEN's funding is funneled through CERES, a shell foundation whose funding sources are shrouded in secrecy. The Foundation for Human Progress is another organization that funds Seralini's research — and this foundation has direct ties to anti-GM activist groups.[51] CRIIGEN was also caught manipulating the embargo system in order to have articles on their study published without having an expert review the results.[52]

[edit] Personal conflicts of interest

Séralini published a book titled Tous cobayes! (which translates to "We're all guinea pigs!") right around when he released his 2012 study.[53] He is a consultant for Sevene Pharma[54] (a homeopathic pharma company),[55] and there is also evidence that he is linked to Invitation to Life, a New Age faith healing cult.[56][57]

[edit] Lawsuits

Séralini has sued at least one person for libel. In November 2010, he sued Marc Fellous (professor of genetics at the University of Paris) for defamation. In January 2011, Mark Fellous was held liable for defamation, but the judges would only rule on his claim that Séralini's relationship with Greenpeace was a conflict of interest, saying that the other comments were part of scientific debate.

[edit] Hasty exit from the Cato debate

Séralini and Jeffrey Smith were scheduled to debate with Jon Entine and Anastasia Bodnar at the Cato Institute (yes, they're the reasonable ones here) on June 4th, 2013. When Anastasia had to cancel and Kevin Folta took her place, Jeffrey Smith withdrew from the event. Séralini stated that he would not debate either Entine or Folta, and abruptly left the debate.[58]
