Well, Lepus, if you're arguing as a veggie, that's fair enough. But otherwise, pretty well every part of a pig is edible. I remember, during rationing times, some Irish cousins sent us half a pig's head, and the wrapping came apart as the postman was delivering it. He had the same kind of reaction as Lepus. Good eating though.

If you kill it, you eat it. (I believe that slugs are especially keen on this basic life rule.) And if you worry about "the filth from beer vats", you'd never be able to bring yourself to drink another pint.
