Mandatory CCTV in slaughterhouses has been shown to improve welfare compliance where implemented. Understanding the evidence and advocacy landscape helps supporters push for broader adoption.
Mandatory slaughterhouse CCTV represents one of the most practical and effective welfare enforcement tools available. Slaughterhouses are among the most welfare-critical points in the animal agriculture system — the conditions and methods of killing directly determine whether animals die quickly and with minimal suffering or slowly and in distress. Without surveillance, violations are extremely difficult to detect and prosecute given the closed and fast-moving nature of slaughterhouse operations. The evidence from England shows that mandatory CCTV with official review improves compliance and provides an evidentiary basis for prosecution. Advocates in jurisdictions without mandatory CCTV should prioritise this campaign.
