Surovand and his colleagues set out to discover if Monsanto’s genetically modified (GM) soy, grown on 91% of US soybean fields, leads to problems in growth or reproduction. The study, jointly conducted by Surov’s Institute of Ecology and Evolution of the Russian Academy of Sciences and the National Association for Gene Security, is expected to be published in July.
After feeding hamsters for two years over three generations,most Genetically Modified (GM) soy-fed hamsters lost the ability to have babies. They also suffered slower growth, and a high mortality rate among the pups.
They used 5 pairs of Campbell hamsters per group, each of which produced 7-8 litters, totally 140 animals.
Surov selected new pairs from each group, which generated another 39 litters. There were 52 pups born to the control group and 78 to the non-GM soy group. In the GM soy group, however, only 40 pups were born. And of these, 25% died. This was a fivefold higher death rate than the 5% seen among the controls. Of the hamsters that ate high GM soy content, only a single female hamster gave birth. She had 16 pups; about 20% died.
Surov said “The low numbers in F2 showed that many animals were sterile.”
