Some religions prohibit drinking or eating blood or food made from blood. In Islam the consumption of blood is prohibited (Haram). Halal animals should be properly slaughtered to drain out the blood. Unlike in other traditions, this is not because blood is revered or holy, but simply because blood is considered ritually unclean or Najis, with certain narratives prescribing ablutions (in the case of no availability of water) if contact is made with it. In Judaism all mammal and bird meat (not fish) is salted to remove the blood. Jews follow the teaching in Leviticus, that since "the life of the animal is in the blood" or "blood was reserved for the forgiveness of sins and thus reserved for God", no person may eat (or drink) the blood. Iglesia ni Cristo and Jehovah's Witnesses prohibit eating or drinking any blood.
