HPAI H5N1 was confirmed in commercial poultry near Dereham, Breckland, Norfolk on 12 November 2026 (case AIV 2026/28). A 3km protection zone and 10km surveillance zone were declared, and all birds on the premises will be culled.
Each infected commercial flock removes laying or meat birds from supply and tightens UK poultry and egg availability, which can lift local poultry and egg prices. A single farm is a modest driver, so the impact on global feed demand is limited.
