Mandatory closed-circuit television monitoring in slaughterhouses has proven effective at improving welfare compliance and reducing violations in jurisdictions where it has been implemented.
CCTV monitoring changes behavior — in slaughterhouses as elsewhere. The knowledge that all actions are recorded and reviewable reduces corner-cutting, rough handling, and deliberate cruelty. Evidence from the UK program demonstrates reduced welfare incidents after introduction. Independent access to footage — by enforcement bodies and accredited auditors — is essential for the deterrent effect to function fully. Public access provisions would further strengthen accountability.
