Pig disease surveillance

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.

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

Pig Expert Group (PEG) veterinary lead

PEG veterinary lead - Susanna WilliamsonThe PEG veterinary lead is Susanna Williamson (01284 724499).

Susanna has been the PEG veterinary lead since April 2014. She leads the Defra-funded pig disease scanning surveillance project in APHA, and is a former President of the Pig Veterinary Society.

Susanna also represents APHA on the Pig Health and Welfare Council (PHWC) and the PHWC antimicrobials and surveillance subgroups.

PEG members

To support the PEG veterinary lead, the group has representation from Veterinary Investigation Officers from APHA and a SRUC Veterinary Services 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 non-APHA members include representatives from:

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.
