Greenpeace has claimed there is unapproved GM corn in Kellogg's meat-free hotdogs. The environmentalist group says that Kellogg's Morningstar Farms corndogs contain Starlink corn, which is not approved for human consumption. Although Kellogg is still testing the batch, there's a good chance it is indeed tainted. The reputation of US corn will be further damaged by the claims, damaging consumer confidence and harming exports.
