In 2006, documents were published by the United States Food and Drug Administration （FDA）.
They suggested that cloned animals and cloned animal products would be allowed into the American food supply.
The FDA has stated that cloned animal products are safe for consumption, and has performed many studies to support this view. In fact, products from cloned animals have already been eaten by some Americans without ill effects. The FDA analyzed the structure and content of cloned animal products and compared it with that of traditionally reproduced animals, and discovered no statistical difference between the two.
Consumers raised serious concerns about cloned animals. The first is the question of whether or not cloned tissue and animal products are truly safe. The second is that many clones are also genetically modified（转基因的）animals, which the FDA has said are unsafe for human consumption. The third is that consumers want to be able to choose what they put into their bodies.
The first concern about cloned animals is almost unnecessary due to the price of producing a clone. Making a clone needs hard work and is very costly. These clones live spoiled lives because they are very valuable, despite biologists' warning that cloned animals decrease diversity.
The second concern, about genetic modification of cloned animals, is more problematic. It may be very difficult to separate genetically modified animals from normal ones. The purpose of genetically modified cloned animals is unclear, and the FDA hasn't allowed their products onto the market, due to health concerns, but the risk of genetic pollution of healthy animals still exists.
Finally, the matter of choice is a large one. Many animal rights activists are worried about clone rights because cloned or not, the animals still have lives. Other consumers are simply trying to eat healthy foods, and have doubts about the cloned animals. If the FDA does not make labeling laws, people may not be able to make informed choices about their food.
