Vets working with livestock play a crucial role in identifying new and emerging diseases, protecting animal health, public health, and the environment. Vets are key in early disease detection. 

Surveillance involves the systematic collection, analysis, and interpretation of data, and the dissemination of information to those who need it to take action. The goal of veterinary scanning surveillance in Great Britain (GB) is to ensure timely detection and investigation of new and re-emerging animal-related disease threats.

Scanning surveillance at APHA is conducted through a network of Veterinary Investigation Centres, partner pathology centres, and diagnostic laboratories. It also includes intelligence networks and horizon scanning. Private veterinary surgeons are fundamental to this programme, as their work in veterinary practice is key to detecting emerging disease threats.
