Cattle disease surveillance
If you have found something new, unusual, severe, or unresponsive in relation to cattle diseases, please contact the CEG veterinary lead Vanessa Swinson (0208 5654574) 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 cattle disease surveillance dashboard.
