Pre-slaughter stunning renders animals insensible before killing, and its requirement is one of the most impactful animal welfare policies applicable to large numbers of animals.
Pre-slaughter stunning, when performed effectively, is one of the most impactful animal welfare interventions available: it converts a painful death into an insensible one for billions of animals annually. The welfare stakes of stunning failure are correspondingly high: an animal that recovers consciousness during the killing process experiences severe pain and distress. Stunning failure rates — documented through slaughterhouse monitoring — reveal the gap between policy intent and practice. Religious exemptions that permit slaughter without stunning create welfare concerns for significant numbers of animals. Engagement with religious communities about post-stun slaughter options that are accepted as religiously valid by many scholars offers a welfare-compatible path that respects religious practice.
