We may not roast the pesach-offering either on a [metal] spit or on a roasting tray.  R' Tzadok said: It once happened that Rabban Gamliel said to Tavi, his slave, “Go out and roast for us the pesach-offering on the roasting tray.”  [If] it touched the earthenware of the oven, he must pare off its place. [If] some of its juice dripped onto the earthenware and dripped back onto it, he must remove its place. If some of its juice dripped on the flour, he must remove a handful from its place.

[If] he smeared it with oil of terumah, if the group is composed of Kohanim, they may eat. If [it is composed of] Israelites, [then:] if it is raw, he must rinse it; but if it is roasted, he must pare the outside.  [If] he smeared it with oil of the second tithe, its value may not be charged to the members of the company, since second tithe may not be redeemed in Jerusalem.

Five things may be offered in a state of con-tamination, but may not be eaten in a state of contamination: the Omer, the Two Loaves, the Panim Breads, the public peace-offerings, and the he-goats of the New Moons.  [But] the pesach-offering that is offered in con-tamination may be eaten in contamination, because its original purpose is only for eating.

[If] the flesh [of the pesach-offering] became contaminated but the fat remained [uncontaminated], one may not throw the blood. [If] the fat became contaminated but the flesh remained [uncontaminated] he throws the blood. But in the case of [other] consecrated animals it is not so. Rather, even when the flesh became contaminated and the fat remained [uncontaminated] he throws the blood.
