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

PEG members

To support the PEG veterinary lead, the group has representation from Veterinary Investigation Officers from APHA, SRUC Veterinary Services and the SRUC-VS pig disease surveillance lead representative. In addition, there are APHA members on PEG providing expertise for specific disciplines (e.g. epidemiology, pathology, virology) and specific diseases (e.g. porcine reproductive and respiratory syndrome, swine influenza).

There is also representation from those involved in International Disease Monitoring, International Trade and Field Veterinary Epidemiology in APHA and from Defra policy.

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 Disease Surveillance and 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 potential new or re-emerging threats to pig health or changing trends among existing ones.
