This week, a French research team published a paper in a peer-reviewed US journal showing that rats exposed to low doses of both genetically modified corn and the widely used herbicide Roundup had negative health effects. The results, already generating plenty of debate, are not as clear-cut as they seem at first glance. But they do shine a harsh light on the ag-biotech industry's mantra that GMOs have indisputably proven safe to eat—and establish an urgent need for more long-term research.
