Do GMOs cause health problems in people? The governments of America, Canada and Australia say genetically engineered foods have proven their safety over the 20 years they have been part of the food chain. According to the USDA, “the risks of genetically engineered (GE) organisms are not fundamentally different from risks posed by non-GE organisms with similar traits.”
Eighty transgenic crops have received regulatory clearance in our country, though only about a dozen are currently marketed for human consumption. Because these dozen include corn and soy beans, though, 70% of US grocery store foods include GMO ingredients.
American federal agencies agree with highly respected and persuasive scientific institutions here and in Great Britain who maintain there is no evidence GMOs harm people. These groups characterize GMO opponents as touchy-feely, mushy-headed conspiracy theorists who don’t understand hard science.
On the other side, opponents of GMOs say there is plenty of real evidence that GMO foods are unsafe. They maintain that most of the entities who claim GMOs harmless have significant vested interest in them, that the vast majority of safety trials have been run by the biotech industry itself, without government oversight, and there is no public access to data produced in private that contradicts safety claims. They also say there are virtually no long-term trials that would prove safety with more certainty.
