Halal food is that which adheres to Islamic law, as defined in the Koran. The Islamic form of slaughtering animals or poultry, dhabiha, involves killing through a cut to the jugular vein, carotid artery and windpipe. Animals must be alive and healthy at the time of slaughter and all blood is drained from the carcass.
If it wasn’t for Halal it wouldn’t be a problem.
