Halakhah su Levitico 6:11

That is that He commanded the priests to eat the remainders of the grain offerings. And that is His, may He be exalted, saying, "What is left of it shall be eaten by Aharon and his sons; it shall be eaten as matzot" (Leviticus 6:9). And the language of the [Sifra] (Sifra, Tzav, Section 9:1-2) is, "'It shall be eaten' - is a commandment. Similar to this, 'her levirate husband shall come to her' (Deuteronomy 25:5) - is a commandment." This means to say that eating the remainders of the grain offerings is like the sexual intercourse of the levirate husband, which is a positive commandment and not just a permitted matter. And the laws of this commandment have already been explained in Tractate Menachot. And the language of the Torah about this commandment is specific to males - and that is His, may He be exalted, saying, "Every male among the Children of Aharon may eat it" (Leviticus 6:11). (See Parashat Tzav; Mishneh Torah, Sacrificial Procedure 10.)

And it is practiced at the time of the [Temple] by the males of the priesthood, as it is stated (Leviticus 6:11), "Every male of the Children of Aharon shall eat it." [If] he transgressed and did not eat it, he has violated this positive commandment.
