Many consider snails (escargot) a delicacy. I think they are too rubbery and fishy tasting.
http://en.wikipedia.org/wiki/EscargotIf most saw some of the water that the US catfish are raised in many would not eat catfish either. Pen raised pigs, cows, turkeys, and chickens are usually held in pretty filthy conditions walking around in their own deep manure layer in the pen. Most non-farmers do not ever see this. I once saw cows in knee deep manure with dried manure on their lower legs. All this does not affect the meat flavor. Food production animals are not always washed clean like those you see at the county fairs.
