But as these crops begin infiltrating our food supply,environmental and consumer groups have begun to question whether potential risks to the environment and human health have been adequately studied.Last year,for example,biologists for the first time found evidence suggesting that planting genetically modified corn in open fields may kill butterflies who feed on the corn’s pollen.Scientists are also questioning whether foods with a gene inserted to improve one area of their performance could prove detrimental in another :for one thing,the genes might cause allergic reactions in people who never had a reaction to that food before.
