“These studies have been carried-out using rats and other animals by scientific researchers from all over the world,” she said.  “No unexpected adverse effect has been reported.”

The design of the Seralini experiment was unusual and statistical controls lacking, scientists said.

“The incidence of tumors in rats reported over many studies and many years is the same as that reported in the paper,” Dr. Newell-McGloughlin said.  “This study does not provide any greater evidence of statistical significance above random occurrence for these animals.”

“The bottom line is, despite numerous studies in the peer-reviewed scientific literature, and substantial experience with humans and animals around the world consuming biotech crops for over 15 years, there has not been a single substantiated case of negative outcomes or a single documented health problem,” she said. 

Seralini’s previous work has been rejected by European experts.  The European Food Safety Authority (EFSA) examined a previous animal feeding study paper by Seralini and others and said: “Following a detailed statistical review and analysis by an EFSA Task Force, EFSA’s GMO Panel has concluded that this re-analysis of the data does not raise any new safety concerns.”

“The statistical analysis made by the authors of the paper did not take into account certain important statistical considerations,” the EFSA panel noted.  “The assumptions underlying the statistical methodology employed by the authors led to misleading results ... EFSA considers that the paper does not present a sound scientific justification in order to question the safety” of the biotech corn being studied.
