This study has been very controversial. The paper was originally published in Food and Chemical Toxicology and was retracted due to concerns with methodology, statistical problems and unsupported conclusions. The retraction notice can be read here. The paper was republished without review in Environmental Sciences Europe and is available here. Séralini’s response to the retraction can be found on his web site. Responses from the scientific community are listed below, including a study commissioned by the European Union that refutes the findings of Séralini (last link).
