IT IS FORBIDDEN BY TORAH TO EAT UNCLEAN FOOD

Leviticus 11:41 And every creeping thing that creeps upon the earth shall be an abomination; it shall not be eaten.

Leviticus 11:42 Whatsoever goes upon the belly and whatsoever goes upon all four or whatsoever has more feet among all creeping things that creep upon the earth, them you shall not eat; for they are an abomination.
