Previous daf Chulin 46
CHULIN 46 - dedicated by Avi Berger of Queens, N.Y. in memory of his
father, Reb Pinchas ben Reb Avraham Yitzchak, on the day of his Yahrzeit.
1) THE SPINAL CORD OF A BIRD
(a) (R. Yanai): The spinal cord of a bird extends until below
the wings (if the majority is cut, it is Tereifah);
2) A REMOVED LIVER
(b) (Reish Lakish): It extends until between the wings.
(c) Ben Pazi was checking a bird. He checked until between
the wings, and was called to the Nasi's house; he went.
1. Ula: I don't know if he holds like Reish Lakish,
that no more needs to be checked, or if he stopped
in the middle out of respect for the Nasi.
(a) (Mishnah): If the liver was removed...
3) A PUNCTURED LUNG
(b) Inference: If anything remains, even less than k'Zayis
(an olive's worth), it is Kosher.
(c) Contradiction (Mishnah): If k'Zayis of the liver remains,
it is Kosher.
(d) Answer (Rav Yosef): One Mishnah is like R. Chiya, the
other is like R. Shimon bar Rebbi.
1. Version #1: R. Chiya would throw out an animal if
less than k'Zayis of the liver remained; R. Shimon
bar Rebbi would eat it.
(e) (R. Zeira): A k'Zayis of the liver must remain in the
area of the gall bladder.
2. Version #2: R. Chiya would not eat liver (for he did
not consider it such a vital organ); R. Shimon bar
Rebbi would eat it (since it is a crucial organ, it
is healthy to eat; (end of Version #2)
i. Presumably, R. Shimon holds that if a tiny
amount of the liver remained, it could not
heal, the animal would be Tereifah).
ii. A way to remember the opinions - rich people
(i.e. the son of the Nasi) economize.
(f) (Rav Ada bar Ahavah): It must remain in the place the
liver is suspended from.
(g) (Rav Papa): We are concerned for both opinions, k'Zayis
must remain in each place.
(h) Questions (R. Yirmeyah): What if the k'Zayis is not all
in one place? What if it is stretched out in a strip?
(i) Question (Rav Ashi): What if it is like a thin sheet?
1. These questions are unresolved.
(j) Question (R. Zerika): If the liver is uprooted in several
places, but still clings to the surrounding Chelev, what
is the law?
(k) Answer (R. Ami): Since it is intact, k'Zayis remains in
both places, it is Kosher.
(a) (Mishnah): A punctured lung...
(b) Version #1 (Rav, Shmuel and Rav Asi): If the outer
membrane is punctured, it is Tereifah.
(c) Version #2 (Rav, Shmuel and Rav Asi): If the inner
membrane is (also) punctured, it is Tereifah.
(d) If only the outer membrane is punctured, surely the lower
one protects (so the animal is not Tereifah), like Rava
1. (Rava): If the outer membrane of the lung was peeled
off but the red inner membrane remains, it is
(e) Question: If only the inner membrane was punctured, does
the outer one protect?
(f) Answer: Rav Acha and Ravina argued - one said that it
protects, the other said it does not.
1. The Halachah is, it protects, like Rav Yosef.
(g) (Rava): If the outer membrane of the lung was peeled off
but the red inner membrane remains, it is Kosher.
2. (Rav Yosef): If when one blows into the lungs it
sounds as if air is escaping, he must check it;
3. If he knows where the sound comes from - he puts a
feather, piece of straw or some spit there. If there
really is a hole, it will move when he blows.
4. If he does not know where the sound comes from, he
puts the lungs in a basin of lukewarm water and
blows into the lungs.
i. Hot water may not be used - this would
constrict the hole.
5. If he sees bubbles, there is a hole, it is Tereifah;
ii. Cold water should not be used - this could
cause the outer membrane to tear.
i. If there are no bubbles, the noise was due to a
tear in the inner membrane alone, it is Kosher.
(h) (Rava): If part of the lung turned red, it is Kosher; if
it all turned red, it is Tereifah.
(i) Objection (Ravina): You say that if only part turns red
it is Kosher, because it can get better;
1. Also if the entire lung turns red, it can get
(j) (Ravina): Rather, whether part or all is red, it is
Kosher (Rashi; Tosfos - Tereifah).
2. (Beraisa): If one wounds a Sheretz (except for the
eight Sheratzim listed in the Torah) on Shabbos he
is exempt unless blood comes out, even if the blood
is recognizable in the skin. (This shows that
redness does not indicate a puncture.)
3. Suggestion: Perhaps Rava learns from the eight
i. (Beraisa): If one wounds one of the eight
Sheratzim on Shabbos he is liable if the blood
is recognizable in the skin, even if it did not
4. Rejection: If so, even a redness in part of the
lungs should be Tereifah!
(k) (Rava): If a lung partially dried up, it is Tereifah.
(l) Question: How much must it dry up?
(m) Answer (Rav Papa): In order that it can be crushed with a
1. Suggestion: This is like R. Yosi ben ha'Meshulam.
(n) (Rava): If the lung has black or colored crusts - it is
i. (Beraisa): A dried ear is a blemish if it would
not bleed when punctured;
2. Rejection: No, it is even like Chachamim.
ii. R. Yosi ben ha'Meshulam says, it is a blemish
if it can be crushed with a fingernail.
i. The ear is exposed to wind, therefore it will
not heal; the lung can heal.
(o) (Ameimar): If a punctured blister is found in the lung,
we do not compare it to a fresh blister (to determine
whether it was there from before the slaughter).
(p) (Rava): If a scab is found between two non-adjacent
chambers of the lungs, it does not help to check (even if
no puncture is found, the animal is Tereifah);
1. If it is between two adjacent chambers, it will heal,
it is Kosher.
