If you asked people in some parts of the world what the most disgusting thing we (westerners) eat, it would be cheese -- pour milk from an animal in a container, add bacteria, let it set until it gets hard . . . even better let it age.
Personally, I've eaten snake, turtle, frog, octopus, abalone, just about anything else from the sea, racoon, beaver (both kinds), snails, blood sausage, tripe, and my Grandma used to make some kind of kidney stew (don't remember where the kidneys came from).
It just barely occured to me to mention crawfish and bullhead and squid.
