Stunning Failures in Slaughter: Welfare Evidence

Inadequate stunning before slaughter means that animals may regain consciousness before death, experiencing significant pain and distress in what should be their final moments.

Key Facts

Up to 10% of cattle stunned with captive bolt may require a second stun for effective insensibility
Inadequate electrical stunning in poultry is common, particularly with live dip stunning systems
Religious slaughter without pre-stunning is permitted in many countries including the EU
Studies show that some sheep slaughtered without pre-stunning remain conscious for over 20 seconds
CCTV in slaughter facilities is associated with measurable reductions in stunning failures

Welfare Considerations

Animals that regain consciousness after inadequate stunning, or that are not stunned before slaughter, may experience the pain of cutting, blood loss, and dying while conscious. The welfare impact of stunning failure is severe and acute. The scale of slaughter operations — billions of animals annually — means that even low failure rates translate to enormous numbers of welfare incidents.
