Is it legal to eat guinea pigs in the United States? Specifically, Tennessee?

On Bizarre Foods with Andrew Zimmer, they seem to be very popular in Peru, and the images looked tasty. I’m always up for trying new things, but it almost looks like I’d have to raise my own. I want to know if it’s legal first, though.

Personally, I don’t think it’s any more odd than eating a rabbit. The argument that lots of people keep guinea pigs as pets doesn’t really matter to me, as people keep pigs as pets, too, but I’m not giving up my bacon.
