Chullin 47 - Rosh Chodesh Tamuz - June 16, 1 Tamuz

Rava establishes further laws regarding physical anomalies that render a lung a treifa. If cysts appear on the lung, a single cyst does not disqualify the animal, whereas two distinct cysts render it a treifa. Rava provides a method to inspect an ambiguous cyst to determine whether it is a single divided structure or two separate entities. Regarding the lobes of the lung - which normally consist of three on the right and two on the left – Rava rules that deviations from this norm disqualify the animal. Meriemar permitted an extra lobe provided it is perfectly aligned with the natural row. However, if an extra lobe develops internally facing the heart, its status is disputed, as Rav Huna Mar bar Avia notes that this configuration is common in wild animals, and therefore permits it. Rafram rules that a lung resembling a wood chip is a treifa, a tradition that receives five distinct interpretations in the Gemara to clarify in what way it is similar to a wood chip – in color or in feel. Rava delineates which lung discolorations are valid and which are problematic, a discussion expanded upon by Rav Kahana and Rav Sama regarding specific shades and appearances. Ravina addresses a scenario where a lobe of the lung fails to inflate, explaining that a test must be performed to determine if the lack of airflow is due to a fatal defect or merely a temporary obstruction. Ulla rules that if the internal tissue of the lung liquefies, the animal remains kosher because internal decay does not compromise the outer membrane. Rava qualifies this leniency, limiting it to cases where the primary bronchial tubes remain intact, and Rav Ashi outlines the practical examination method to verify their structural integrity.
