2,309. A Treifa
Maachalos Assuros 4:5
The placenta that comes out with a newborn animal may not be eaten. One who eats it isn’t liable, though, because it’s not meat.
Maachalos Assuros 4:6
If a person eats an olive-sized piece of a kosher domesticated or wild animal or bird that was mortally wounded, he is liable for lashes as per Exodus 22:30, “Do not eat meat of an animal that was torn in the field. Throw it to the dogs.” The term “treifa” in the Torah means mortally wounded by a wild animal like a lion, a tiger, etc., or a bird mortally wounded by a bird of prey like a hawk, etc. One can’t say that “treifa” means an animal that was attacked and killed because if it died, it would be a neveila. There’s no difference between if an animal dies on its own, is killed by the sword, or is mauled to death by a lion; “treifa” must therefore mean that an animal was mortally wounded but didn’t die.
