French GM study not scientifically valid

Last month’s study out of France that said genetically modified corn and a related herbicide caused organ damage, tumors, and early death among rats broke too many rules and should be dismissed as “of insufficient scientific quality,” the European Food Safety Authority (EFSA) says.

When it was published in Food and Chemical Toxicology in September, the study led by Professor Gilles-Eric Séralini seemed like it might be a game-changer because it questioned the safety of Roundup Ready corn, or NK 603, manufactured for use in both the U.S. and Europe by biotech giant Monsanto.
