All bird keepers are urged to remain vigilant and take action to protect their birds following the recent cases of highly pathogenic avian influenza (HPAI).
Avian Influenza Prevention Zones (AIPZ) mandating enhanced biosecurity are in force across the UK (separate AIPZs are declared in each administration). In addition, mandatory housing for kept birds is in force in England across the unitary authorities of the East Riding of Yorkshire, the unitary authority of York, the City of Kingston upon Hull and all districts in Cheshire, County Durham, Cumbria, Herefordshire, Merseyside, Lancashire, Lincolnshire, Norfolk, Northumberland, North Yorkshire, Shropshire, Suffolk, Tyneside and Worcestershire and all areas of Northern Ireland to mitigate the risk of further outbreaks of disease occurring.
Keepers can check if they are in an avian influenza disease control or prevention zone in GB using the Animal and Plant Health Agency’s (APHA) interactive map and in Northern Ireland using DAERA’s interactive map
Further information on the measures that apply in disease control zones can be found in Defra’s Bird flu: rules in disease control zones in England - GOV.UK guidance and the zone declarations available via the notifiable disease case finder on gov.uk.
Disease control zones will remain in place until all disease control and surveillance activities in the zones have been successfully completed and there are no suspect cases are under investigation in the zones.
Details of the current national risk levels for avian influenza can be found at gov.uk/birdflu with further information on the evidence which supports these levels available in APHA’s risk and outbreak assessments.
Practicing good biosecurity at all times protects the health and welfare of birds and for commercial keepers will help protect their business from HPAI and other diseases.
