   in some religions, an unclean animal is an animal whose consumption or handling is taboo. according to these religions, persons who handle such animals may need to ritually purify themselves to get rid of their uncleanliness. ==judaism== in judaism, the concept of "unclean animals", or more accurately "impure animals", plays a prominent role in the kashrut, the part of jewish law that specifies which foods are allowed (kosher) or forbidden to jews. these laws are based upon the books of leviticus and deuteronomy of the torah and in the extensive body of rabbinical commentaries (the talmud). the concept of unclean animals is also mentioned in the book of genesis, when noah is instructed to bring into the ark all sorts "of pure beasts, and of beasts that are impure, and of fowls, and of every thing that creepeth upon the earth". in the torah, some animals are explicitly named as pure or impure, while others are classified by anatomical characteristics or other criteria. in some cases, there is some doubt as to the precise meaning of the biblical hebrew animal name. according to jewish dietary laws, to be "pure" an animal must also be free from certain defects, and must be slaughtered and cleaned according to specific regulations (shechita). any product of an impure or improperly slaughtered animal is also non-kosher. animal gelatin, for example, has been avoided, although recently kosher gelatin (from cows or from fish prepared according to kosher regulations) has become available.
