How slaughter plant welfare monitoring works and what evidence shows about the gap between standards and practice.
Slaughter plant welfare monitoring represents the final welfare assurance point for billions of farm animals annually and the one that is most difficult to verify. The welfare outcomes at slaughter are determined by the quality of stunning equipment, the skill and diligence of operators, the management culture of the facility and the effectiveness of official oversight. All four of these factors are variable and imperfectly monitored. CCTV systems provide an audit trail but only improve welfare when footage is reviewed and action is taken in response to identified violations. The welfare improvement most needed in slaughter plant monitoring is not more cameras but more consistent, independent review of footage and faster regulatory response to violations.
