SUMMARY
1. A needle is found to have penetrated through the thickness of the reticulum of an animal. If the needle is protruding on one side, the animal is Kosher, but if it is protruding on both sides, the animal is a Tereifah.
2. If a needle is found in the large blood vessel of the liver, according to Huna Mar bar Rav Idi the animal is a Tereifah. Rav Ada bar Minyumi disagrees.
3. If a date pit is found in the gallbladder, the animal is Kosher. If an olive pit is found there, the animal is a Tereifah.
4. When the lung of an animal is found to be punctured in a place where it was handled by the butcher, there is a disagreement about whether the puncture is assumed to have occurred after Shechitah.
5. While the Kohanim bless Yisrael, Hashem blesses the Kohanim.
6. The Kohanim were in the practice of permitting to themselves the fat on the abomasum, in accordance with the view of Rebbi Yishmael, who permitted it in the name of his forefathers.
7. According to Rav, only Kosher fat effectively seals a puncture hole that otherwise would render the animal a Tereifah. According to Rav Sheshes, even non-Kosher fat seals a puncture hole.
8. The Chelev of a Chayah which corresponds to the non-Kosher Chelev of a Behemah does not effectively seal a puncture hole, according to Rav, even though its Chelev is Kosher.
9. According to the Tana Kama, if fish brine, vinegar, oil, honey, or fish sauce is exposed and left out unattended, there is no concern that a snake drank from it. Rebbi Shimon disagrees.

A BIT MORE
1. When the needle protrudes only on one side, that indicates that it punctured the inner layer but not the outer layer, and thus the animal is not a Tereifah. If the needle also punctured the outer layer, the animal is a Tereifah.
2. According to Huna Mar bar Rav Idi, the animal is a Tereifah, because he rules that the needle was probably in the esophagus originally and created a puncture while moving through the digestive tract to get to the liver. Rav Ada bar Minyumi disagrees, because he maintains that the needle is assumed to have been in the trachea and then made its way down to the liver. Therefore, the animal is Kosher.
3. A date pit is not sharp enough to puncture the digestive tract, and therefore it must have entered the gallbladder by way of the blood vessel in the liver. In contrast, an olive pit is sharp enough to puncture the digestive tract.
4. According to one opinion, we assume that the puncture was made by the butcher in the process of handling the lung, and the animal is not a Tereifah.
5. According to Rebbi Yishmael, the Kohanim are blessed with the same blessing as Yisrael. According to Rebbi Akiva, the Kohanim are blessed because Hashem said, "I will bless those who bless you."
6. Rebbi Yishmael himself prohibits the fat on the abomasums, while Rebbi Akiva permits it. However, even Rebbi Akiva agrees that the fat on the intestines is prohibited.
7. Kosher fat adheres tightly to the punctured organ, so if the intestines are punctured the Kosher fat that is attached to them seals the hole. If the paunch is punctured, the non-Kosher fat on it does not adhere to it and does not effectively seal it off, according to Rav. Rav Sheshes does not distinguish between Kosher and non-Kosher fats.
8. All Chelev of a Chayah is permitted. However, the Chelev that corresponds to the non-Kosher Chelev of a Behemah does not effectively seal off a puncture hole. The fact that it is Kosher does not change the reality that it does not adhere as tightly as the Chelev which corresponds to the Kosher Chelev of a Behemah.
9. If water, wine, or milk is left exposed and unattended, it may not be used, because of the concern that a snake drank from it and injected venom into it. However, regarding fish brine, vinegar, oil, honey, and fish sauce, there is a disagreement about whether there is a concern that a snake drank from it.
