Highly pathogenic avian influenza H5N1 was confirmed at commercial poultry farms in North Lincolnshire and the Scottish Borders in early November. Authorities established protection and surveillance zones, and poultry at both affected farms are being culled; the cases bring the UK’s 2026–27 outbreak-season total to four, including one H5N5 case.
Culling directly removes birds from production, while control zones can constrain nearby poultry movements, tightening UK poultry supply and potentially supporting chicken prices. The reported loss is concentrated at two farms, limiting the likely market impact.
