“This study was just routine,” said Russian biologist Alexey V. Surov, in what could end up as the understatement of this century. Surov 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. What he discovered may uproot a multi-billion dollar industry.
After feeding hamsters for two years over three generations, those on the GM diet, and especially the group on the maximum GM soy diet, showed devastating results. By the third generation, most GM soy-fed hamsters lost the ability to have babies. They also suffered slower growth, and a high mortality rate among the pups.
And if this isn’t shocking enough, some in the third generation even had hair growing inside their mouths–a phenomenon rarely seen, but apparently more prevalent among hamsters eating GM soy.
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 three months (July 2010)–so the technical details will have to wait. But Surov sketched out the basic set up for me in an email.
He used Campbell hamsters, with a fast reproduction rate, divided into 4 groups. All were fed a normal diet, but one was without any soy, another had non-GM soy, a third used GM soy, and a fourth contained higher amounts of GM soy. They used 5 pairs of hamsters per group, each of which produced 7-8 litters, totally 140 animals.
Surov told The Voice of Russia,
“Originally, everything went smoothly. However, we noticed quite a serious effect when we selected new pairs from their cubs and continued to feed them as before. These pairs’ growth rate was slower and reached their sexual maturity slowly.”
He 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 [third generation] showed that many animals were sterile.”
The published paper will also include measurements of organ size for the third generation animals, including testes, spleen, uterus, etc. And if the team can raise sufficient funds, they will also analyze hormone levels in collected blood samples.
Hair Growing in the Mouth
Earlier this year, Surov co-authored a paper in Doklady Biological Sciences showing that in rare instances, hair grows inside recessed pouches in the mouths of hamsters.
“Some of these pouches contained single hairs; others, thick bundles of colorless or pigmented hairs reaching as high as the chewing surface of the teeth. Sometimes, the tooth row was surrounded with a regular brush of hair bundles on both sides. The hairs grew vertically and had sharp ends, often covered with lumps of a mucous.”
(The photos of these hair bundles are truly disgusting. Trust me, or look for yourself.)
At the conclusion of the study, the authors surmise that such an astounding defect may be due to the diet of hamsters raised in the laboratory. They write, “This pathology may be exacerbated by elements of the food that are absent in natural food, such as genetically modified (GM) ingredients (GM soybean or maize meal) or contaminants (pesticides, mycotoxins, heavy metals, etc.).” Indeed, the number of hairy mouthed hamsters was much higher among the third generation of GM soy fed animals than anywhere Surov had seen before.
Preliminary, but Ominous
Surov warns against jumping to early conclusions. He said, “It is quite possible that the GMO does not cause these effects by itself.” Surov wants to make the analysis of the feed components a priority, to discover just what is causing the effect and how.
In addition to the GMOs, it could be contaminants, he said, or higher herbicide residues, such as Roundup. There is in fact much higher levels of Roundup on these beans; they’re called “Roundup Ready.” Bacterial genes are forced into their DNA so that the plants can tolerate Monsanto’s Roundup herbicide. Therefore, GM soy always carries the double threat of higher herbicide content, couple with any side effects of genetic engineering.
