1) The new regulations do not cover cloned animals, most pets or research animals. The FDA has already determined that clones -- genetic replicas -- are safe. Pets and research animals are unlikely to enter the food chain
2) Only one genetically engineered animal is now being sold in the United States, the glow-in-the-dark zebra fish for aquariums. The FDA approved it because it is not eaten and its need for warm water effectively precludes its escape into the wild
3) Technically, it is not the modified animals but the added DNA segments that are considered drugs
