Avian disease surveillance

If you have found something new, unusual, severe, or unresponsive in relation to avian diseases, please contact the AEG veterinary lead or your nearest Veterinary Investigation Centre.

Please note: if you suspect a notifiable disease you must contact APHA immediately.

AEG members

To support the AEG veterinary lead, the group has representation from Veterinary Investigation Officers and avian pathologists from APHA and a SRUC Veterinary Services representative.

AEG surveillance reports

AEG contributes interesting and unusual avian cases, highlights avian disease alerts or findings and provides focus articles relating to poultry and gamebirds for the APHA Veterinary Record monthly disease surveillance report. These are compiled together with contributions from other Species Expert Groups.

Quarterly GB Avian Disease Surveillance and Emerging Threats reports are compiled by the AEG. They summarise investigations into threats and other surveillance issues to inform governments, the veterinary profession and livestock farming industries of new or re-emerging threats to avian health or changing trends among existing ones.
