@Crazy Me,
It is the USDA and the FDA sharing the oversight.
Here is a snip of the article,
Cell-based meat is produced using poultry and livestock cells that have the ability to self-renew. Those cells are placed into bioreactor tanks, where they are fed nutrients and oxygen, helping muscle tissue to grow. In a matter of weeks, developers say, the tissue can be harvested as meat and formed into products ranging from beef meatballs to chicken strips.
