Our daf cites several rulings of R’ Nachman regarding lungs. If a lung was punctured, which is one of the signs of tereifus, but the hole in the lung became adhered to the chest wall, it is kosher.
Ravina adds and clarifies that this is only true if the place of the hole became attached to the flesh of the chest, between the ribs, and not to the ribs themselves.
According to Rashi, this results in a strong connection that will not loosen. If the place of the hole in the lung adheres to the rib itself, this connection is not strong enough to alleviate the tereifah concern.
We continue our review of kashrut in different communities and including the issue of stunning.
