Adopts a 1995 IOMS fatwa that allows a slight amount of alcohol as a solvent for colours and preservatives, and alcohol on the skin, but says foods containing wine are not permitted even in a small ratio. Pig fat and pig rennet are prohibited; rennet from a correctly slaughtered animal is permitted; most participants hold rennet from an animal that was not slaughtered impure while some disagree; rennet made by genetic engineering is permitted. Pig heparin only under necessity. Gelatin was referred for further study with no ruling.
