Gilles-Eric Seralini, professor of molecular biology at Caen University and a member of the Committee for Independent Research and Information on Genetic Engineering (CRIIGEN) is internationally well known and respected for independent research on the toxicology of GMOs and pesticides for the past 15 years. He and his team published the first long-term toxicity study of a pesticide and a GMO in 2012. This was confirmed and republished with new data in June 2014. Human exposure to Roundup residues and their bioaccumulation is still poorly characterized and needs to be further investigated.


By supporting our team, you will be contributing to experiments on:

  • Measuring contamination of foodstuffs by pesticides and GMO
  • Measuring contamination of laboratory animal diets by Roundup residues and other environmental pollutants
  • Starting a research program on Roundup bioaccumulation in the organs kept from the 2012 toxicity study and other experiments

S�ralini led a study on GM maize and Roundup herbicide involving 200 rats over a period of two years; it found an alarming increase in early death, large tumours including cancers, and diseases of the liver and kidney. The study, published in 2012 by the journal Food and Chemical Toxicology (FCT), was the most in-depth long-term toxicological study ever done. Significantly, many of the most damaging effects came after 90 days, the officially mandated period of feeding trials for regulatory approval of GMOs, exposing the gross inadequacy of current regulation, and challenging the biotech propaganda that GMO is safe.

A concerted worldwide campaign to discredit the findings followed, including ex-Monsanto employee Richard Goodman being appointed to a newly created post of associate editor for biotechnology at FCT. This eventually resulted in the unilateral withdrawal of the paper from FCT a year after it was published. The retraction was unprecedented, unwarranted, and a clear violation of the international ethical norms as prescribed by COPE (Committee on Publication Ethics). It was a blatant attempt by vested interests to erase the crucial findings off the public record. ISIS launched an Open Letter on Retraction and Pledge to Boycott that attracted nearly 6 000 signatures among them 1 381 scientists. Public support and the determination of the team were crucial to the republication of the paper in Environmental Sciences Europe in June 2014.

The battle for transparent and adequate risk assessment for GMOs is by no means over. The S�ralini team are determined more than ever before to carry out further key investigations (see Project below) and need your support.


The project will measure the presence of Roundup residues in the organs and diets of rats fed GMOs (genetically modified organisms) and/or Roundup residues, in particular from experiments first reported in the ‘retracted paper’ now republished. Additional analysis will be performed from this experiment in order to understand the metabolic disturbances reported in the liver and kidneys of rats exposed to the GMO and/or Roundup.
Scientists still do not know what levels of residues can bioaccumulate from a GMO-rich diet. Around 80% of agricultural GMOs are Roundup-tolerant plants, which are permitted to contain residues of glyphosate at a level of up to 500 ppm. Transgenic soy imported into the EU has been found to routinely contain 10-100 ppm. Our previous research found toxic effects in rats from 0.1 ppb (1 000 times less). A rigorous scientific paper based on this work will shed new light on GMO toxicology and bring pressure to bear for more stringent regulation.

This project is part of a comprehensive research programme of risk assessment on GMOs and associated pesticides. More details here
