How technological advances in poultry stunning monitoring improve welfare outcomes and what the evidence shows about current system performance.
Poultry stunning welfare is a technological and governance problem as much as a procedural one. Many of the welfare failures in conventional water bath stunning are systemic — the result of birds missing the stunner due to line speed, incorrect positioning, or equipment malfunction — rather than individual acts of negligence. Technology that monitors stunning effectiveness in real-time, combined with robust CCTV oversight and genuine regulatory enforcement, can identify and correct these failures. The transition to controlled atmosphere stunning, which eliminates the pre-stun electrical shock problem entirely, represents the most transformative available improvement, though capital costs create barriers to rapid adoption.
