    4月15日至6月5日，在俄罗斯一年一度的的环境危害防御活动中宣布了一项独立研究的结果。科学家已经证明：转基因生物对哺乳动物是有害的。研究人员发现，食用转基因食品的动物将失去繁殖能力。实验选择农业中广泛应用的含有不同比例转基因成分的普通大豆，喂养具有快速繁殖率的坎贝尔仓鼠2年。另外一组比对仓鼠，喂以在塞尔维亚难以发现的纯大豆，因为世界上95%的大豆是转基因大豆。

    实验由全国基因安全协会和生态与环境问题研究所联合进行。Alexei Surov 博士说：“我们将仓鼠分成若干组，在笼中成对以普通食物喂养。第一组不喂任何东西，另一组喂含不有转基因成分的大豆，第三组的含有一些转基因成分，第四组喂大量的转基因食品。监控它们的行为、体重变化以及产仔时间。起初，一切顺利。但是当从幼仔中选择了新的并继续按照前述方式进行喂养时，我们注意到了相当严重的影响。这些子代仓鼠成长缓慢，性成熟缓慢。当他们生出下一代仓鼠时我们称其为第三代。用转基因食品喂养的仓鼠没有生出下一代，这证明它们失去了生育能力。”

    科学家们还发现另一个令人惊讶的危害。第三代仓鼠的口中长出了毛发。目前研究人员还不明白为什么动物食用转基因食品时，会产生破坏性的效果。他们说，只有通过停止吃这些食品才可以消除这些影响。因此，科学家建议禁止转基因食品，直到它们被证明具有生物安全性。俄罗斯科学家的研究结果与法国和奥地利的一致。其中，在法国，当科学家认为转基因玉米对哺乳动物有害后，立即禁止其生产和销售。进行这项研究的科学家指出，目前要对转基因食品对健康的长远危害下一个结论，还为时过早。他们坚持认为有必要进行全面的研究。他们建议在莫斯科附近的“安全基因科技”创新中心“Skolkovo”，实施该项目。

    Russia says genetically modified foods are harmful

    Russia has started the annual Days of Defence against Environmental Hazards from the 15th of April to the 5th of June with the announcement of sensational results of an independent work of research. Scientists have proved that Genetically Modified Organisms are harmful for mammals. The researchers discovered that animals that eat GM foodstuffs lose their ability to reproduce. Campbell hamsters that have a fast reproduction rate were fed for two years with ordinary soya beans, which are widely used in agriculture and those contain different percentages of GM organisms. Another group of hamsters, the control group, was fed with pure soya, which was found with great difficulty in Serbia because 95 percent of soya in the world is transgenic.

    Concerning the experiment carried out jointly by the National Association for Gene Security and the Institute of Ecological and Evolutional Problems, Dr. Alexei Surov has this to say. “We selected several groups of hamsters, kept them in pairs in cells and gave them ordinary food as always,” says Alexei Surov. “We did not add anything for one group but the other was fed with soya that contained no GM components, while the third group with some content of Genetically Modified Organisms and the fourth one with increased amount of GMO. We monitored their behavior and how they gain weight and when they give birth to their cubs. 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. When we got some of their cubs we formed the new pairs of the third generation. We failed to get cubs from these pairs, which were fed with GM foodstuffs. It was proved that these pairs lost their ability to give birth to their cubs,” Dr. Alexei Surov said.

    Another surprise was discovered by scientists in hamsters of the third generation. Hair grew in the mouth of the animals that took part in the experiment. It’s unclear why this happened. The researchers cannot understand why a programme of destruction is launched when animals take GMO foodstuffs. They say that this can be neutralized only by stopping to eat these foods. Consequently, scientists suggest imposing a ban on the use of GM foods until they are tested for their bio-security. The results of Russian scientists coincide with those of their colleagues from France and Austria. For one, when scientist proved that GM maize was harmful for mammals, France banned immediately its production and sale. The scientists who carried out the experiment say that it’s too early to make far-reaching conclusions about the health hazards of the GMO. They insist that there is a need to carry out comprehensive research. They suggest implementing the project, “Safety Gene Technology” at the innovation centre, “Skolkovo” which is being set up near Moscow.
