A vegetarian-foods subsidiary of Kellogg’s announced a recall in the U.S. on Tuesday of all its meatless corn dogs after tests confirmed that some of them contained a genetically engineered corn variety not approved for human consumption. Greenpeace first spotted that the corn variety, StarLink, was showing up in the dogs, and went public with the problem last week. StarLink prompted other recalls last year when it was found in Taco Bell shells sold in supermarkets and other food products.
