Bird flu has been confirmed among a small flock of chickens at a Northumberland farm.
A 3km (1.8-mile) protection zone and a 10km (six-mile) surveillance zone have been put in place around the infected property near Haltwhistle after the H5N8 avian flu outbreak was confirmed.
The flock contains about 35 birds, the Department for Environment, Food and Rural Affairs (Defra) said.
A number have died with the remaining birds being euthanised.
An investigation is under way to determine the source of the infection.
Public Health England advises the risk to public health from the virus is "very low" while the Food Standards Agency says bird flu does not pose a food safety risk in the UK.
