Re eating poisonous snakes: I learned that several decades ago, when I was a boy, from reading compilations of my grandparents' (even much older) Foxfire magazines. These were 'tame' hogs, but the principle still applies: they stomp on the heads of the snakes, and then
FLAY
THEM
ALIVE
--peeling the skins back. Until the snakes die. Or not, the hogs don't care. Skins go first either way.
I still have those, or Mom does rather. (The Foxfire compilations, not the hog-stripped snake skins.) It occurs to me now that some of those articles involve absolute rubbish tall tales, like snakes rolling along after tucking their tails in their mouths; but the snake-eating method sounded one thousand percent plausible to me.
In conclusion: hogs are like the Reavers from Firefly. Or maybe vice versa.
