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

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

Pig Expert Group (PEG) veterinary lead

PEG members

To support the PEG veterinary lead, the group has representation from Veterinary Investigation Officers from APHA and a SRUC, SAC Consulting Veterinary Services representative. In addition, there are APHA members on PEG providing expertise for specific disciplines (e.g. bacteriology, 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 and International Trade in APHA.

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.
