If a company plans to put the meat or milk from cloned livestock into the U.S. food supply, they had better get permission from the U.S. Food and Drug Administration.

The agency is working on developing policy guidelines on whether non-genetically modified cloned animal products need pre-market approval similar to drugs, or if the technology is in the same class as in-vitro fertilization, which is more loosely regulated.

Right now, FDA is waiting for the National Academy of Sciences to complete a study determining if cloned animal products present any safety risks for humans, animals or the environment. The report is due out sometime early next year.

In the meantime, FDA is urging companies that clone livestock to fill out an application if they’re planning to sell cloned animal food products. So far, no one has filed an application. Cloning does bring up a lot more ethical questions, especially when it comes to humans. Now it’s just a waiting game.
