1If the gullet is perforated in any amount, the animal is a tereifa , as taught in the mishna (42a). Therefore, if the gullet is clawed and any amount of its flesh reddens, the animal is a tereifa as well. But a perforation of the windpipe renders the animal a tereifa only where it is the size of an issar . If clawed, what amount of its flesh must redden in order to render it a tereifa ? After he raised the dilemma he then resolved it: Both this and that render the animal a tereifa if any amount of its flesh reddened. What is the reason for this? It is because its venom burns continuously around the circumference of the hole and widens it.
2The Gemara relates: Rav Yitzḥak bar Shmuel bar Marta sat before Rav Naḥman, and he was sitting and saying: A clawed animal, about which the Sages said one must be concerned, requires inspection adjacent to the intestines to see that the flesh has not reddened. Rav Naḥman said to him: By God! Rav would teach that it must be inspected over its entire body, from the flesh around the hollow to that of the thigh.
3The Gemara asks: What is the hollow? If we say that it is the hollow of the foreleg, i.e., its shoulder, then the area between it and the thigh is the same as the area adjacent to the intestines, and Rav Naḥman has said nothing new. Rather, Rav Naḥman referred to the area from the hollow of the brain, i.e., the skull, to the thigh.
4The Gemara relates that when Rav Ḥiyya bar Yosef went up from Babylonia to Eretz Yisrael, he found that Rabbi Yoḥanan and Reish Lakish were sitting and saying: A clawed animal, about which they said one must be concerned, requires inspection adjacent to the intestines. Rav Ḥiyya bar Yosef said to them: By God! Rav would teach that it must be inspected from the flesh around the hollow to that of the thigh. Reish Lakish said to him: Who is this Rav, and who is this Rav? I do not know who he is.
5Rabbi Yoḥanan said to him: But don’t you remember that student who served the great Rabbi Yehuda HaNasi and Rabbi Ḥiyya and studied under them? But by God! All those years that this student served in the yeshiva, he was held to be one of the most important students and was allowed to sit during study, while I held a lower status and served while standing up. And who was greater? He was greater in all things, in Torah and piety.
6Immediately, Reish Lakish began to speak and said: Indeed [ beram ], that man, Rav, is remembered for the good, as they said this halakha in his name: If an animal’s windpipe is dislocated from the throat, and it has already been slaughtered, and it is uncertain whether it was dislocated before or after slaughter, the animal is kosher, as it is impossible for an animal with a dislocated windpipe to be slaughtered. A dislocated windpipe would have slipped away from the knife, and therefore the animal must have been slaughtered while it was still attached.
7And Rabbi Yoḥanan says: This is not certain; rather, one should bring the windpipe, make a new slit in it, and compare the two slits. If they are similar, then the first slit by the slaughtering knife was also made after the windpipe was dislocated, and the animal is a tereifa . If they are different, then the slaughter preceded the dislocation of the windpipe and the animal is kosher.
8Rav Naḥman said: The Sages taught that it is impossible to slaughter a dislocated windpipe only in cases where he did not grip the simanim during slaughter. But if he gripped the simanim and slaughtered the animal, then it is possible for an animal with a dislocated windpipe to be slaughtered, since it will not slip away from the knife.
9§ The mishna states: This is the principle: Any animal that was injured such that an animal in a similar condition could not live for an extended period is a tereifa . The Gemara asks: What case does this principle add that was not previously mentioned? The Gemara responds: It was stated to add seven halakhot of tereifot taught by amora’im and not listed in the mishna. These cases are enumerated on 42b.
10The Gemara recounts: The men of the house of Yosef the hunter would strike the sciatic nerve of an animal with an arrow and kill it that way. In other words, the animal would die from that wound. They came before Rabbi Yehuda ben Beteira to ask if an animal with an injured sciatic nerve is a tereifa , which is relevant if the animal was slaughtered before it died. Rabbi Yehuda ben Beteira said to them: And is it possible to add to the list of tereifot ? You have only what the Sages counted, and the Sages mentioned no such tereifa .
11Likewise, the men of Rav Pappa bar Abba the hunter would strike an animal in the kidney with an arrow and kill it that way. They came before Rabbi Abba to ask if such an animal is a tereifa . Rabbi Abba said to them: And is it possible to add to the list of tereifot ? You have only what the Sages counted.
12The Gemara objects: But we see that they die. Isn’t this an indication that the animal is a tereifa ? The Gemara responds: It is learned as a tradition that in all these cases, if one were to scatter medicine on the wound, the animal would live. An animal is not considered a tereifa unless it cannot be healed.
13MISHNA: And these, despite their condition, are kosher in an animal: If its windpipe was perforated or cracked lengthwise. How much can the windpipe be missing and still be kosher? Rabban Shimon ben Gamliel says: Until the perforation is the same size as the Italian issar . If the skull was fractured but the membrane of the brain was not perforated, it is kosher. If the heart was perforated and the perforation did not reach its chamber, or if the spinal column was broken but its cord was not cut, or if the liver was removed and an olive-bulk of it remained, it is kosher.
14Additionally, it is kosher if the omasum or the reticulum was perforated one into the other. If the spleen was removed, or the kidneys were removed, or if its lower jaw was removed, or if its womb was removed, or if its lung shriveled by the hand of Heaven, the animal is kosher. In the case of an animal whose hide was removed, Rabbi Meir deems it kosher, and the Rabbis deem it a tereifa and unfit for consumption.
15GEMARA: The mishna begins: And these are kosher, while the previous mishna begins: These are tereifot . With regard to this, it was stated that Rabbi Yoḥanan says: The tanna intended the phrase: These are tereifot , specifically, teaching that an animal is kosher in another case. The list of kosher cases here is therefore not exhaustive. And Rabbi Shimon ben Lakish says that the tanna intended the phrase: These are kosher, specifically, teaching that an animal is a tereifa in another case. The list of tereifot at the beginning of the chapter is therefore not exhaustive.
16The Gemara explains: With regard to what case do they disagree? They disagree with regard to the statement of Rav Mattana, as Rav Mattana says: This head of the femur that was completely dislocated renders the animal a tereifa . According to Rabbi Yoḥanan, who says that the phrase: These are tereifot , is meant specifically, the tanna taught the list of tereifot and taught afterward: This is the principle, to add cases that were not stated explicitly;
