New study on Long term toxicity of a Roundup herbicide

A group of French and Italian researchers from the Universities of Caen and Verona recently published results from a long-term rat feeding experiment in the scientific journal “Food and Chemical Toxicology” which concluded that inclusion of the herbicide Round-up (at concentrations well below officially set safety limits) and/or Round-up tolerant, genetically modified  maize in rat diets increases (a) the proportions of rats with tumors, and (b) the speed of tumor development (Séralini et al. 2012).

Several senior scientists from UK Universities and Research Institutes quickly criticised various aspects of the study and there was relatively little media coverage.

Below we provide links to criticisms, endorsements, and news coverage relating to the study, because we feel that both the study and the reaction to it by the scientific community and media raise a range of important questions:

For example, I have asked myself:

  • Why is this the first study in which the health effects of long-term dietary exposure to GM-crops was tested?
  • Why does the European Food Standard Agency (EFSA) insist that longer-term exposure experiments are not necessary for safety testing of GM-crops?
  • Why have the scientists which criticised the study not requested that it be repeated using an improved design and using a range of other GM-crops?
  • Why have the UK media been so quiet about this study?
