 Debate continues among Muslim jurists and the general Muslim population about whether or not stunning, anesthetics, or other forms of inducing unconsciousness in the animal prior to slaughter are permissible as per Islam.Several halal food authorities have more recently permitted the use of a recently developed fail-safe system of head-only stunning where the shock is less painful and non-fatal and where it is possible to reverse the procedure and revive the animal after the shock.According to the British Halal Food Authority, stunning is permissible.
