Leviticus 7:18-19

7:18 If some of the meat of his peace offering sacrifice is ever eaten on the third day it will not be accepted; it will not be accounted to the one who presented it, since it is spoiled, and the person who eats from it will bear his punishment for iniquity. 7:19 The meat which touches anything ceremonially unclean must not be eaten; it must be burned up in the fire. As for ceremonially clean meat, everyone who is ceremonially clean may eat the meat.
