2,584. Seventy Reasons Why

Hilchos Shechita 10:8

If an animal has high blood pressure, or black or white secretions from the gall bladder, or if it ate poison that kills animals, or if it drank rancid water, it is permitted. If it ate poison that kills people or was bitten by a snake or something similar, it’s not a treifa but the animal is prohibited because of the potential danger.
