TRADITIONAL varieties of major US food crops have been widely contaminated by DNA from genetically modified crops. Some scientists have gone as far as to suggest that this may pose a serious risk to human health.
Crops engineered to produce industrial chemicals and drugs – so-called “pharm” crops – could already be poisoning ostensibly GM-free crops grown for food, says a study by the Union of Concerned ÒÁÈ˾þÃs (UCS), based in Cambridge, Massachusetts. “If genes find their way from pharm crops to ordinary corn, they or their products could wind up in drug-laced cornflakes,” says microbiologist Margaret Mellon, the report’s co-author.
