Why don’t Muslims eat pork?

Reasons Behind the Dietary Restrictions on Pork

In the context of Abrahamic faiths, the consumption of pork is explicitly prohibited by the dietary regulations of Judaism (kashrut), Islam (halal), and certain branches of Christianity, such as the Adventists who follow kosher practices. Within both Judaism and Islam, as well as in segments of Christianity, the pig is regarded as an impure animal and is thus deemed unacceptable as food.
