The food must come from a supplier that uses halal practices. Specifically, the slaughter must be performed by a Muslim, who must precede the slaughter by invoking the name of Allah, most commonly by saying "Bismillah" ("In the name of God") and then three times "Allahu akbar" (God is the greatest). Then, the animal must be slaughtered with a sharp knife by cutting the throat, windpipe and the blood vessels in the neck (while the animal is conscious), causing the animal’s death without cutting the spinal cord. Lastly, the blood from the veins must be drained.
