Farm Poultry Pre-Slaughter Stunning Welfare

Pre-slaughter stunning of poultry is required by EU law but exemptions and compliance failures mean millions of birds are slaughtered without effective insensibility.

Key Facts

Water bath electrical stunning — the most common poultry slaughter method — requires birds to be shackled and dragged through electrified water.
Shackling causes pain from leg joint pressure; pre-stun shocks from water bath entry are common and cause additional distress.
Controlled atmosphere killing (CAK) using inert gas or CO2 allows birds to be stunned in transport containers — avoiding shackling welfare costs.
Religious slaughter exemptions allow halal and kosher slaughter without pre-slaughter stunning in many jurisdictions.
Neck cutting of inadequately stunned birds occurs at a measurable rate in water bath systems — birds may regain consciousness at bleed-out.

Welfare Considerations

Poultry pre-slaughter welfare involves the final minutes of billions of birds' lives. The shackling and water bath system causes fear and pain before the kill — birds hang inverted and experience electric shock before neck cutting. Controlled atmosphere systems are welfare-superior by eliminating shackling and pre-stun shocks, but require capital investment that many processors resist. Consumer and regulatory pressure for welfare-superior killing systems is the most accessible lever for improving the final welfare experience of the billions of chickens slaughtered annually.

What You Can Do

Choose poultry from producers using controlled atmosphere stunning rather than water bath systems.
Support campaigns for mandatory controlled atmosphere stunning in poultry slaughter facilities.
Contact food companies to ask about the stunning methods used in their poultry supply chains.
Reduce poultry consumption overall as the most direct way to reduce the number of birds experiencing pre-slaughter stress.
