Chullin 112b (קיב:) — the Talmud in English

Rav Aḥa, son of Rav Ika, said to Rav Ashi: But did Shmuel say this?

But didn’t Shmuel say: A loaf upon which one cut meat is forbidden to eat!?

Rav Ashi said to him:

That case is different,

with regard to a loaf upon which meat was cut with a knife,

because due to the pressure of the knife it expels

the blood that remained absorbed in the meat.

Rav Naḥman said: Fish and poultry that were salted together—

are forbidden,

the fish, because the blood that emerges from the poultry is absorbed by the fish; and all the more so if one salted the poultry together with another species of meat.

And we raised a difficulty:

What are the circumstances? If

he salted them together

in an unperforated vessel,

and all the other items become forbidden because they absorb the blood that emerges from the poultry, if so,

even poultry and poultry should also be forbidden,

because the blood that emerged from this bird is absorbed by the other bird.

If it was in a perforated vessel, even fish and poultry should also be permitted,

since the blood drains downward.

And we answer:

Actually, it is in a perforated vessel.

And

fish

are different—

because their membranes are loose,

as their membrane [the skin covering their bodies] is soft; therefore

they hasten to expel.

And

if

poultry are constricted,

they do not quickly expel their blood, and therefore the fish become forbidden, because

once the fish have finished expelling

their blood, there are still

the poultry’s emissions, and afterward,

since the fish are no longer occupied with expelling their blood,

they absorb from it,

from the blood of the poultry. But the meat of an animal salted together with poultry does not become forbidden, because it is occupied with expelling throughout the entire time that the poultry are expelling; and as long as it is expelling, it does not absorb.

Rav Mari bar Raḥel salted kosher-slaughtered meat together with the meat of a tereifa.

Although he salted them in the usual manner of salting, in a perforated vessel, he was uncertain whether here too we say that as long as it is expelling, it does not absorb, and therefore it makes no difference that the blood of the tereifa drains onto the kosher-slaughtered meat, or whether this case is different.

He came before Rava.

He said to him:

From the verse in which it is written, "

the impure"—

they derive

that their brine, gravy, and sediment are forbidden.

That is, although the blood of the tereifa is not absorbed by the kosher-slaughtered meat, since the kosher-slaughtered meat is occupied, like the tereifa, with expelling its blood and does not absorb while it is occupied with expelling, in addition to blood, fluid also emerges from the tereifa. This fluid is more readily absorbed than blood, and it is absorbed by the kosher meat even while it is occupied with expelling its blood.
