what cherimoya said!
i am leery of pig organs only because my pigs had liver flukes and they were out in the middle of an organic farm. we slopped them food we ate which was all organic, majority from the farm, and they ate tons of scraps from the farm and orchard. i even made a point to bring them tons of greens each day, they lived with chickens that ate nothing but farm scraps and some scratch grains. i have no idea where they got em from but they seem to be particularly susceptible. i never got to eat any of their muscle meat but i would have cooked it, i only watched them get slaughtered and cleaned and left the farm before they came back from the butcher.
