I have never had rattlesnake meat, though I'm not adverse to trying it someday. I know there's a city in west Texas, I think it's Sweetwater, that has a rattlesnake cookoff every year. Apparently, people use this powder made from rattlesnake meat to cure ailments, which can be bad. It can cause salmonella, which is something I wouldn't be excited about catching. Hopefully it doesn't show up on the rattlesnake steaks, especially if I dare try one (I've had gator, which was OK, kinda gamey).
I don't care much for snakes, mostly because so many of them can kill me, and I was attacked by a cottonmouth when I was 11. However, this is more disconcerting for me, because I would normally hope that a snake can't kill me after it's dead, especially if it's trying to make me better.
