N185 – Forbidden Fats

And the LORD spoke to Moses, saying: Speak to the Israelite people thus: You shall eat no fat of ox or sheep or goat. Fat from animals that died or were torn by beasts may be put to any use, but you must not eat it. If anyone eats the fat of animals from which offerings by fire may be made to the LORD, the person who eats it shall be cut off from his kin.

Leviticus 7:22-25
