In September 2012 the journal Food and Chemical Toxicology (FCT) published the research of a team led by the French biologist Professor Gilles-Eric Séralini, which found liver and kidney toxicity and hormonal disturbances in rats fed Monsanto’s GM maize NK603 and very small doses of the Roundup herbicide it is grown with, over a long-term period. An additional observation was a trend of increased tumours in most treatment groups.
In November 2013 the study was retracted by the journal’s editor, A. Wallace Hayes, after the appointment of a former Monsanto scientist, Richard E. Goodman, to the editorial board and a non-transparent review process by nameless people that took several months.
Did Monsanto pressure the journal Food and Chemical Toxicology (FCT) to retract the study? French journalist Stéphane Foucart addresses this question in an article for Le Monde.
