Mass culling of poultry flocks during avian influenza outbreaks causes enormous welfare suffering and raises urgent questions about the speed and methods used in emergency depopulation.
Mass poultry culling during avian influenza outbreaks represents one of the most acute and large-scale welfare emergencies in animal farming. The scale — hundreds of millions of birds per outbreak cycle — combined with the speed required by disease control protocols creates conditions where welfare considerations may be compromised in favour of rapid depopulation. Some emergency methods, particularly ventilation shutdown with or without heat, have been criticised by welfare organisations as causing prolonged suffering before death. The welfare-positive approach to emergency depopulation requires pre-planning for adequate supply of high-welfare killing equipment, training of personnel, and regulatory frameworks that require welfare-conscious methods even under time pressure. The underlying welfare problem is the intensification of poultry production that creates conditions where a single infected bird can require the killing of millions of others.
