Most offspring died when mother rats ate GM soy.

The Russian scientist planned a simple experiment to see if eating genetically modified (GM) soy might influence offspring. What she got was an astounding result that may threaten a multi-billion dollar industry.

Irina Ermakova, a leading scientist at the Institute of Higher Nervous Activity and Neurophysiology of the Russian Academy of Sciences (RAS), added GM soy flour (5-7 grams) to the diet of female rats. Other females were fed non-GM soy or no soy at all. The experimental diet began two weeks before the rats conceived and continued through pregnancy and nursing.

Ermakova's first surprise came when her pregnant rats started giving birth. Some pups from GM-fed mothers were quite a bit smaller. After two weeks, 36% of them weighed less than 20 grams compared to about 6% from the other groups.

But the real shock came when the rats started dying. Within three weeks, 25 of the 45 rats (55.6%) from the GM soy group died compared to only 3 of 33 (9%) from the non-GM soy group and 3 of 44 (6.8%) from the non-soy controls.

Ermakova preserved several major organs from the mother rats and offspring, drew up designs for a detailed organ analysis, created plans to repeat and expand the feeding trial, and promptly ran out of research money.

Therefore, when she was invited to present her research at a symposium organized by the National Association for Genetic Security, Ermakova wrote "Preliminary Studies" on the top of her paper. She presented it on October 10, 2005 at a session devoted to the risks of GM food.

Her findings are hardly welcomed by an industry already steeped in controversy.

GM soy's divisive past

The soy she was testing was Monsanto's Roundup Ready variety. Its DNA has bacterial genes added that allow the soy plant to survive applications of Monsanto's "Roundup" brand herbicide. About 85% of the soy grown in the US is Roundup Ready. Since soy derivatives, including oil, flour and lecithin, are found in the majority of processed foods sold in the US, many Americans eat ingredients derived from Roundup Ready soy everyday.

The FDA does not require any safety tests on genetically modified foods. If Monsanto or other biotech companies declare their foods safe, the agency has no further questions. The rationale for this hands-off position is a sentence in the FDA's 1992 policy that states, "The agency is not aware of any information showing that foods derived by these new methods differ from other foods in any meaningful or uniform way." [1] The statement, it turns out, was deceptive. Documents made public from a lawsuit years later revealed that the FDA's own experts agreed that GM foods are different and might lead to hard-to-detect allergens, toxins, new diseases or nutritional problems. They had urged their superiors to require long-term safety studies, but were ignored. The person in charge of FDA policy was, conveniently, Monsanto's former attorney (and later their vice president). One FDA microbiologist described the GM food policy as "just a political document" without scientific basis, and warned that industry would "not do the tests that they would

normally do" since the FDA didn't require any. [2] He was correct.
