Don't eat the rich. Humans contain a lot of toxins that are harmful to humans, and eating them doubles up on that. Also they contain (obviously enough) human vector diseases that you can catch in a way eating another species you wouldn't necessarily; Compost the rich and use them to grow other crops instead.
@jackofallEves @DamienGranz actually you want to cook the compost to get rid of the remaining diseases. Then it can be used for fertilizer with the rest of the vegetable compost.
