The authors of the report GMO Myths and Truths concluded that the claims to the safety of genetically engineered foods are simply not true but are lies.
A recent science-based investigation into the claims of genetically engineered foods concludes that the scientific evidence does not support the safety and efficacy claims made
There are three potential sources of adverse health effects from genetically engineered foods: the genetically modified (GM) gene product (for example, the Bt toxin in crops that generate its own internal insecticide); the genetic transformation process; and changes in farming practices
Results of genetically engineering crops include toxicity, increased allergenic potential, mutagenic effects, alterations in biological structure and function, reduced nutritional value, increased toxic residues
Russian scientists recently announced evidence of “very serious health risks for animals given genetically modified feed.” A number of pathological changes were discovered, including a delay in development and growth; a distortion of the sex ratio in the offspring; and a progressive reduction in the number of offspring up to complete infertility by the third generation of offspring fed genetically engineered feed
