Leviticus 7:17-19

Amplified Bible

¹⁷ but what is left over from the meat of the sacrifice on the third day shall be [completely] burned in the fire. ¹⁸ If any of the meat of the sacrifice of his peace offerings is ever eaten on the third day, then it will not be accepted, and the one who brought it will not be credited with it. It shall be an abhorred (offensive) thing; the one who eats it shall bear his own guilt.

¹⁹ ‘The meat that comes in contact with anything that is unclean shall not be eaten; it shall be burned in the fire. As for other meat, everyone who is [ceremonially] clean may eat it.
