Leviticus 7:18-21

18If any of the meat of his fellowship sacrifice is eaten on the third day, it will not be accepted. It will not be credited to the one who presents it; it is repulsive. The person who eats any of it will bear his iniquity.

19“Meat that touches anything unclean must not be eaten; it is to be burned. Everyone who is clean may eat any other meat.

20But the one who eats meat from the Lord’s fellowship sacrifice while he is unclean, that person must be cut off from his people.

21If someone touches anything unclean, whether human uncleanness, an unclean animal, or any unclean, abhorrent creature, and eats meat from the Lord’s fellowship sacrifice, that person is to be cut off from his people.”
