Leviticus 7:18-21

18If any meat of the fellowship offering is eaten on the third day, the one who offered it will not be accepted. It will not be reckoned to their credit, for it has become impure; the person who eats any of it will be held responsible.

19“ ‘Meat that touches anything ceremonially unclean must not be eaten; it must be burned up. As for other meat, anyone ceremonially clean may eat it.

20But if anyone who is unclean eats any meat of the fellowship offering belonging to the Lord, they must be cut off from their people.

21Anyone who touches something unclean—whether human uncleanness or an unclean animal or any unclean creature that moves along the ground—and then eats any of the meat of the fellowship offering belonging to the Lord must be cut off from their people.’ ”
