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.

Explore the diagnoses made by the GB surveillance network through the interactive avian disease surveillance dashboard.

Avian Expert Group (AEG) veterinary lead

The AEG veterinary lead is David Welchman (0208 0267640).

David has been the AEG veterinary lead since April 2014. He leads the Defra-funded avian disease scanning surveillance project in APHA, and is a former President of the British Veterinary Poultry Association and current Senior Vice-President. David also represents APHA on the Poultry Health and Welfare Group.

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. In addition, there are APHA members on AEG providing expertise for specific disciplines (e.g. epidemiology, virology) and specific diseases (e.g. avian influenza).

AEG non-APHA members include representatives from:

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.
