2,589. The Inspection of Doubtful Treifos

Hilchos Shechita 11:4

Pursuant to the previous halacha, if a bird’s wing is dislocated, we check to see if its lung was punctured; if an animal fell, we check to see if its organs were crushed; if it’s skull was crushed, we check to see if the membrane of the brain was punctured; if it was poked by a thorn or shot with something like an arrow or a spear that entered the body cavity, we must examine the entire body cavity out of concern that it may have punctured one of the organs that would make an animal a treifa. The same is true in all comparable cases.

Hilchos Shechita 11:5

Accordingly, if there are growths or string-like adhesions on a lung, extending to the ribcage, heart or diaphragm, we are concerned that it may have been punctured, so an examination is required. Similarly, if a swelling contains fluid, we are concerned that a bronchiole beneath may have been punctured, so the lung must be examined.
