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.
