Why is pork haram?

Reasons for Pork Being Considered Haram

In the Abrahamic faiths, the consumption of pig meat is explicitly prohibited according to the dietary laws of Judaism (kashrut), Islam (halal), and certain Christian denominations such as the Adventists (kosher animals). Within Judaism and Islam, the pig is regarded as an impure animal for consumption, and this view is echoed in some branches of Christianity.
