    Re: New EFSA 2-year feeding study guidelines

    To start, the section talking about controls starts by taking from OECD TG 453 standards for long-term studies on chemical effects. For carcinogenicity studies, that standard recommends 50 animals per sex per dose (treatment) group with concurrent control for carcinogenicity studies. If Seralini's study had followed this recommendation and still wanted to do all 9 of their treatment groups, it sounds like they would have needed 50 * 9 = 450 control animals to go with 450 males, then the same for females. Similarly for chronic toxicity, that standard recommends 10 animals per sex per dose group ... again with concurrent control. For Seralini's study that would have been 90 male controls to go with 90 males and 90 female controls to go with 90 females. So right off the bat, we discover that Seralini's study seems to have ignored a pre-existing international recommendation on these kinds of studies!
    I don't know where you pulled the claims you got because you don't cite them properly, but they are bogus.

      This comes from "Long term toxicity of a Roundup herbicide and a Roundup-tolerant genetically modified maize". as published in "Food and Chemical Toxicology, volume 50, no. 11.

      3.1. Mortality

      Control male animals survived on average 624 ± 21 days, whilst females lived for 701 ± 20, during the experiment, plus in each case 5 weeks of age at the beginning and 3 weeks of stabilization period. After mean survival time had elapsed, any deaths that occurred were considered to be largely due to aging. Before this period, 30% control males (three in total) and 20% females (only two) died spontaneously, while up to 50% males and 70% females died in some groups on diets containing the GM maize

      It's the Saralini Study that was validated by the EFSU.

      but the anti -GMO types are out in full force today.

      I don't think it would be enlightening to ask, but I am sincerely curious about what they're so terrified about.
