And the answer is.....who the hell knows. I mean kinda, why is it so important? Aha, it just struck me, you're making "Roadkill Stew" and aren't sure.which species is OK and what is not. Well, I do believe some mountain man has probably penned just such a cookbook. I'd check on Amazon if it were.me.
Good.Luck and all the best for your Stew!
