The liver is a filter for contaminates and waste in a body. I just can’t get that out of my head.
For domesticated food that’s not much of a problem. Wild food, it can be. Especially predators, since they get toxin when they eat liver, and those toxins wind up in their liver. You can get some pretty supercharged unpleasantness. Of course then there’s just the fact that it has a weird texture and doesn’t taste that great.
That is the very reason I don’t eat oysters.
