Avian influenza biosecurity requirements create direct tension with outdoor access welfare for poultry — navigating this trade-off requires evidence-based policy.
The tension between biosecurity and outdoor access welfare is one of the most difficult policy trade-offs in poultry farming. Mandatory housing orders during avian influenza outbreaks impose genuine welfare harms on birds accustomed to outdoor access — they lose exercise space, natural behaviors like foraging, and the environmental complexity that outdoor access provides. These harms are real, even if difficult to quantify against transmission risk reduction. The labelling exception in EU regulations pragmatically recognizes that welfare-certified producers should not be commercially penalized for public health compliance. Long-term solutions include covered outdoor run designs that provide natural behaviors while limiting wild bird contact, and risk-based regional approaches that avoid blanket national restrictions.
