A long-term feeding study commissioned by the Austrian Agency for Health and Food Safety, managed by the Austrian Federal Ministry of Health, Family and Youth, and carried out by Veterinary University Vienna, confirms genetically modified (GM) corn seriously affects reproductive health in mice. Non-GMO advocates, who have warned about this infertility link along with other health risks, now seek an immediate ban of all GM foods and GM crops to protect the health of humankind and the fertility of women around the world.
Feeding mice with genetically modified corn developed by the US-based Monsanto Corporation led to lower fertility and body weight, according to the study conducted by the University of Veterinary Medicine in Vienna. Lead author of the study Professor Zentek said, there was a direct link between the decrease in fertility and the GM diet, and that mice fed with non-GE corn reproduced more efficiently.
The corn is genetically modified with genes that produce a pesticidal toxin, as well as genes that allow it to survive applications of Monsanto’s herbicide Roundup.
A book by author Jeffrey M. Smith, Genetic Roulette, distributed to members of congress last year, documents 65 serious health risks of GM products, including similar fertility problems with GM soy and GM corn: Offspring of rats fed GM soy showed a five-fold increase in mortality, lower birth weights, and the inability to reproduce. Male mice fed GM soy had damaged young sperm cells. The embryo offspring of GM soy-fed mice had altered DNA functioning. Several US farmers reported sterility or fertility problems among pigs and cows fed on GM corn varieties. Additionally, over the last two months, investigators in India have documented fertility problems, abortions, premature births, and other serious health issues, including deaths, among buffaloes fed GM cottonseed products.
The principle GM crops are soy, corn, cottonseed and canola. GM sugar from sugar beets will also be introduced before year’s end.
The biotech industry's claim that genetically modified (GM) foods are safe is shattered in this groundbreaking book. This book, prepared in collaboration with a team of international scientists, is for anyone wanting to understand GM technology, to learn how to protect themselves, or to share their concerns with others. It is presented in the clear, accessible style that made Jeffrey Smith's Seeds of Deception the world's best-selling book on genetically engineered foods. As the world's most complete reference on the health risks of GM foods.
In his foreword to Genetic Roulette, former UK government environment minister Michael Meacher says, “This is the authentic book on genetic modification that the world has been waiting for. . . . The case presented is absolutely a smoking shotgun that should stop in its tracks any dabbling with GM foods, whether by individual families, food companies, or indeed nations.”
