A meta-analysis of 19 studies shows that rats and mice fed on GM soybean and maize developed kidney and liver toxicity. GM soybean and maize represents more than 80 percent of all commercially available GM food.
According to Signs of the Times, the report of the independent concluded:
"From the regulatory tests performed today, it is unacceptable to submit 500 million Europeans and several billions of consumers worldwide to the new pesticide GM-derived foods or feed, this being done without more controls (if any) than the only 3-month-long toxicological tests and using only one mammalian species, especially since there is growing evidence of concern."
The nineteen feeding studies were performed by both industry and independent scientists. A meta-analysis allowa for a more objective appraisal of the evidence, and provides a more precise estimate of effects.
