A vegetarian-foods subsidiary of Kellogg Co. recalled all its meatless corn dogs after its tests confirmed some of them contained a variety of genetically engineered corn that isn't approved for human consumption. The environmental group Greenpeace announced last week that tests it had commissioned detected StarLink corn in corn dogs purchased last month in a Baltimore Safeway. Worthington Foods Inc. said it subsequently had an independent lab test the product. StarLink was never approved for human consumption because of unresolved questions about its potential to cause human reactions. Government officials say there is little, if any, health risk for the corn. Worthington Foods, which was acquired by Kellogg in 1999, "very much regrets this incident," said Carla Cooper, president of the company. The recall includes corn dogs sold under the names Morningstar Farms, Loma Linda and Natural Touch. Consumers may call the company toll-free at (877) 924-4247.
