PEG surveillance reports

PEG contributes interesting and unusual pig cases, highlights pig disease alerts or findings and provides focus articles relating to pigs for the APHA Veterinary Record monthly disease surveillance report. These are compiled together with contributions from other Species Expert groups.

Quarterly GB Pig Diseases Emerging Threats reports are compiled by the PEG. 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 pig health or changing trends among existing ones.
