You’ll notice that they never feed cows human meat.
It’s why I stick with beef.
I remember decades ago there was a serial killer pig farmer in British Columbia who would feed all the hookers he killed to his hogs.
He didn’t use a chipper, just threw the bodies in whole. The hogs took care of it.
All they found was a few broken pieces of chewed up bones in the pen.
As I understand it during WWII troops would often kill pigs they found feeding on human remains.
