Positive Mitzvah 91

A sacrifice offered to HaShem must be treated with care.

Parts of certain sacrifices are eaten by the priests and the people who brought them.

However, the Torah places a specific time limit on eating this meat.

The time limit depends on the type of sacrifice that was brought.

Leftover meat that was not eaten by this time is called Notar and may not be disposed of carelessly (see Negative Mitzvot 1 16-1 17). We must burn any leftover meat.
