Humane slaughter regulations exist in many countries but enforcement is inconsistent and often inadequate.
Humane slaughter legislation represents a minimum welfare floor that protects animals from the worst suffering at the end of life. However, enforcement is inconsistent, and significant populations of animals — particularly poultry in the US — have no legal protection at slaughter. Stunning failures, where animals regain consciousness after inadequate stunning, occur in all slaughter systems at some rate. Mandatory CCTV, reduced line speeds, and rigorous audit requirements all improve slaughter welfare outcomes. The gap between law and practice remains significant in most countries.
