Poultry Pre-Slaughter Handling: Reducing Fear and Pain

Pre-slaughter handling is a critical welfare moment for billions of poultry annually. Modern low-stress handling systems, improved catching methods, and controlled atmosphere stunning dramatically reduce pre-slaughter suffering.

Key Facts

Over 70 billion chickens are slaughtered globally each year; pre-slaughter handling affects all of them
Manual catching and crating for transport causes wing fractures in 0.5-1.5% of broilers, affecting millions of birds
Live hanging on shackle lines before stunning causes pain from wing dislocation and fear from inversion
Controlled atmosphere stunning with nitrogen or argon is considered more humane than electrical water bath stunning
Water bath electrical stunning may not render all birds unconscious before bleeding if parameters are not optimal
Transport and lairage stress from crowding, temperature extremes, and unfamiliar environments causes cortisol spikes
Mechanical harvesting systems reduce fracture and bruising rates compared to manual catching for broilers
The RSPCA and other organizations have campaigned for controlled atmosphere stunning to replace water bath systems

Welfare Considerations

Pre-slaughter welfare for poultry is a high-stakes issue because even small percentage improvements in handling quality affect enormous numbers of animals. A 1% reduction in injury rates during catching translates to hundreds of millions of birds avoiding painful fractures in a single year of global production. The welfare costs of current systems are not negligible: live shackling causes pain and fear, and water bath stunning does not reliably render all birds insensible before slaughter. Controlled atmosphere stunning systems, while requiring capital investment, eliminate the welfare problems of shackling and provide more reliably humane pre-slaughter conditions. Consumer and regulatory pressure is driving adoption of these systems in progressive markets.

What You Can Do

Choose poultry products from farms and processors using controlled atmosphere stunning
Support RSPCA Assured and equivalent certification programs that require improved pre-slaughter handling
Advocate for controlled atmosphere stunning as the legal minimum for commercial poultry slaughter
Engage food companies about their poultry supplier pre-slaughter welfare requirements
Support research into mechanical harvesting systems that reduce manual catching injury rates
Reduce poultry consumption or shift to higher-welfare certified products
