[If] he performed melikah and it was found to be a tereifah — R’ Meir says: It does not contaminate with tumah via the throat; R’ Yehudah says: It contaminates with tumah via the throat. Said R’ Meir: If the carcass of an animal, which transmits tumah through touching and carrying, [yet] its slaughter rids its tereifah of any tumah, [then] the carcass of a bird, which does not transmit tumah through touching and carrying, does it not follow that its shechitah should surely rid its tereifah of any tumah! [Thus,] just as we find regarding shechitah that it renders permissible for eating, and it [also] rids its tereifah of tumah, so too its melikah, which renders permissible for eating, should [also] rid its tereifah of tumah. R’ Yose says: It suffices that it be like an animal carcass, whose shechitah cleanses it [of tumah], but not its melikah.
