["Processing facility" isn't an animal, and there are no non-Pokémon animals (other than fish I think?) here, so questions are being raised, especially since he's personally confirmed that humans can't eat Pokémon.]

Chicken, I guess. I don't have any idea what animal it's from. Pork tastes like boar, only with less taste to it, and beef tastes kind of like deer, but chicken doesn't taste like anything I recognize.
