Feeding shit and trash to pigs, and other animals like chickens or rabbits, used to be a common custom in European countries as well. It's not as terrible as it sounds, since for the most time these animals don't get infected by human germs, effectively acting as a kind of walking antibiotic bag, and therefore it's an acceptable way of disposing of residues and getting some extra food at the same time.
