The mandatory installation of CCTV cameras in slaughterhouses has had measurable impacts on compliance with welfare standards. Understanding the evidence informs debate about further extensions of CCTV requirements.
CCTV in slaughterhouses represents one of the most evidence-supported policy interventions for improving end-of-life welfare for farmed animals. Before CCTV, welfare violations at slaughter were extremely difficult to detect and prosecute. After implementation, the Food Standards Agency has been able to investigate complaints using footage and has found cases of mishandling, inadequate stunning, and other violations. The presence of cameras itself appears to improve compliance through a deterrent effect. Extension of CCTV to more areas of the slaughter process and independent access for welfare bodies would strengthen this effect.
