The Austrian scientists performed several long-term feeding trials with laboratory mice over a course of 20 weeks. One of the studies was a so-called reproductive assessment by continuous breeding (RACB) trial, in which the same parent generation gave birth to several litters of baby mice. The parents were fed either with a diet containing 33% of the GMO corn variety, or a closely related non-GMO variety. A decrease in litter size and weight was found to be statistically significant in the third and fourth litters in the
GMO-fed mice compared to the control group.
"This study clearly demonstrates that GMOs have a lot of unknown environmental and health risks and that the safety of GMO crops can not be guaranteed. This is not the first GMO to have been discovered to pose serious health risks, and it will not be the last.
"GMO food appears to be acting as a birth control agent, potentially leading to infertility--if this is not reason enough to close down the whole biotech industry once and for all, I am not sure what kind of disaster we are waiting for," said Dr. Jan van Aken, GE expert at Greenpeace International. "The reproductive toxicity of this GMO corn was a totally unexpected result, but regulators around the world had considered this GMO corn variety as safe as non-GMO varieties--a potentially devastating error. Playing genetic roulette with our food crops is like playing Russian roulette with consumers and public health."
