Farmers have been advised to remain vigilant for signs of the bluetongue virus in their animals after a sheep tested positive for the disease.
The Department for Environment, Farming and Rural Affairs (Defra) confirmed a ram at a property in Cornwall had tested positive for the disease on Friday.
Defra confirmed the ram had died but other animals on the premises would not be culled since bluetongue virus is mainly spread by biting midges.
The notifiable disease does not pose a threat to human health or food safety but it can affect farmers by making animals sick, reducing milk yields and affecting breeding, Defra added.
