UK records first bird flu outbreak of the season
© Tim Scrivener The UK has recorded its first highly pathogenic avian influenza (HPAI) outbreak of the 2026-27 season, affecting poultry on the Isle of Lewis.
Authorities confirmed HPAI H5N5 in a backyard poultry at Ness, Scotland, prompting them to impose a 3km protection zone and a 10km surveillance zone around the infected premises.

The outbreak, the first since the new season began on 1 October, means Great Britain has lost its HPAI disease-free status, with trade implications.
NFU Scotland poultry chairman Matthew Steel said the confirmation was “deeply concerning”.
“This case is a timely reminder that avian influenza remains a very real threat and that all poultry keepers, regardless of the size of their flock, must remain vigilant,” he said.
“NFU Scotland will continue to monitor the situation closely and work with the Scottish government and relevant agencies to ensure poultry producers and keepers receive clear and timely information as the situation develops.”
Previous losses
The latest case follows two seasons in which HPAI caused substantial losses to UK poultry flocks.
During 2024-25, 82 HPAI outbreaks were confirmed, with at least 2.4m birds culled by late September as part of disease-control measures.
Cases increased to 100 during 2025-26, comprising 79 outbreaks in England, nine in Scotland, seven in Wales and five in Northern Ireland.
The UK’s largest recent outbreak season remains 2022-23, when 207 infected premises were recorded.
