Treifa || טְרֵפָה‎ || Non-Kosher Animals



After shechting an animal, the שוחט checks the animal for any defects. If a defect is found, the animal is declared טְרֵפָה‎ [i.e. will not live because of the defect] and it is not kosher. Often defects are found on the lungs of an animal. If the lung is smooth and healthy it is called Glatt — גלאט — hence the term Glatt Kosher.

It is common usage to say that anything that is not kosher is טְרֵפָה‎.
