It is important that all livestock keepers familiarise themselves with the symptoms of notifiable diseases. These are diseases that because of their seriousness must, where there is any suspicion, be notified immediately to the Divisional Veterinary Manager of Animal and Plant Health Agency (APHA a DEFRA agency). In Buckinghamshire and Surrey the number to call is 01284 778150.
It is vital that if you become aware of any suspicious symptoms that you cannot explain and you do call APHA.
Never ask another livestock keeper to visit to offer an opinion if you suspect a notifiable disease.
