Position of the Italian Federation of Life Sciences on the transgenic maize NK603 study.


The Italian Federation of Life Sciences (FISV) published its position on a French study on maize NK603 which showed that tumours appeared more frequently in rats fed with this transgenic maize.

After examining the study, FISV concluded that the authors did not take into account that the strain of rats they used typically developed spontaneous tumours, especially when fed without restriction. For this reason, the toxicology study had to be conducted in a shorter period of time to conform to OECD guidelines. The Federation said that this research contrasted with many other studies examining the same transgenic crop. According to FISV, the refusal of the authors to disclose their funding sources and complete data set, as well as the organised media campaign, “strongly weakens the paper and the professional credibility of these researchers." To sum up, FISV said,

We conclude that the work of Seralini et al. does not fulfill the minimal requirements for a rigorous scientific publication. Their results do not allow drawing any plausible conclusion neither provide any valid indication that the transgenic maize NK603 or the associated herbicide is toxic. The publication of this study clearly represents a failure of the peer review journal system that accepted a research paper with an impaired experimental design and with no scientific value. We respectfully suggest that the journal retracts the paper.
