Leviticus 7:24-26

Revised Standard Version

²⁴ The fat of an animal that dies of itself, and the fat of one that is torn by beasts, may be put to any other use, but on no account shall you eat it. ²⁵ For every person who eats of the fat of an animal of which an offering by fire is made to the Lord shall be cut off from his people. ²⁶ Moreover you shall eat no blood whatever, whether of fowl or of animal, in any of your dwellings.
