Halal beef is beef that has been prepared according to Islamic law. The word "halal" means "permissible." Beef certified as halal is never from the rear of a cow and will have been slaughtered according to certain guidelines.
The slaughter of animals for halal meat must be accompanied by the utterance of God's name. The knife used should be extremely sharp and drawn across the throat of the conscious animal. It must then be left to hang upside down so that the blood completely drains from the body.
Kosher meat, the Jewish equivalent to halal, is often considered an acceptable alternative by Muslims.
