Any pesach-offering that was taken out or became contaminated must be burned immediately. [If] the owners became contaminated or died, it must become disfigured and be burned on the sixteenth.  R' Yochanan ben Berokah says: This too must be burned immediately, because there are none to eat it.

The bones, the sinews, and the leftover [meat] must be burned on the sixteenth. [If] the sixteenth falls on the Sabbath, they must be burned on the seventeenth, because they do not override the Sabbath or a festival.
