The development of more humane stunning technologies for poultry represents one of the clearest areas where technology has driven genuine welfare improvement in industrial food production.
Poultry stunning technology is a domain where incremental welfare improvement at scale is genuinely achievable. Water bath electrical stunning — requiring conscious shackling — causes pre-stun shocks and allows birds to be electrocuted while conscious if shackling is incomplete. CAS eliminates all of this: birds are rendered unconscious in groups before any handling for slaughter. LAPS uses hypoxia rather than gas and shows positive welfare indicators with birds becoming unconscious in about 40-60 seconds. The technical case for CAS is strong; the economic barrier has been reduced by retailer purchasing requirements. Consumer advocacy targeting major food buyers has been the most effective lever for accelerating adoption.
