Mixing between GM and non-GM varieties has already caused serious economic losses for producers in lost sales and exports. But the consequences of mixing will be much more serious with new crops that are altered to produce pharmaceuticals and industrial chemicals, the scientists argue. The crops could harm human health and be toxic to wild animals.
“What would be the impact societally, economically if for example, cornflakes were contaminated by some sort of drug or chemical? I think it would be a vast impact economically,” said Karen Perry Stillerman, senior food and environment programme analyst with the Union of Concerned Scientists.
“I think it’s really hard to say [what impact contamination would have] because there is a variety of different drugs and chemicals that might be manufactured in plants this way,” she added. “Our perception is that some of them might be toxic, but all of them would certainly cause tremendous economic upheaval.”
The group presented its findings at the American Association for the Advancement of Science conference in Boston.
