Avian Influenza Culling Welfare and Alternatives

Mass culling of poultry during avian influenza outbreaks involves methods that cause significant suffering, and welfare advocates are pushing for improvements in emergency depopulation protocols.

Key Facts

Highly pathogenic avian influenza has resulted in culling of hundreds of millions of birds since 2021
Common culling methods including ventilation shutdown cause prolonged suffering before death
Carbon dioxide and nitrogen foam are considered more humane but require more equipment
The OIE/WOAH recognizes welfare concerns with emergency depopulation and recommends humane methods
Vaccine deployment could prevent outbreaks but faces trade barrier concerns in some markets

Welfare Considerations

Mass culling for avian influenza represents a welfare emergency where the method of death matters enormously. Ventilation shutdown, in which barns are sealed and temperature raised until birds die from heat stress, causes prolonged suffering that may last hours. More humane alternatives including carbon dioxide or nitrogen foam are available but require equipment investment. The welfare case for maintaining emergency depopulation equipment and trained personnel is clear — when outbreaks occur, advance preparation determines whether millions of birds die humanely or not.
