Devon farmers are facing a fresh nightmare after a new case of foot-and-mouth disease was confirmed in Surrey.

UK chief vet Debby Reynolds confirmed the outbreak on land attached to Milton Park Farm, near Egham, on Wednesday afternoon. The farm is made up of a number of different parcels of land.

The affected cattle have been slaughtered, Defra said.

A two-mile protection zone has been placed around each farm holding, while a six-mile (10km) control zone has also been imposed. Footpaths within the protection zone have been closed.

Defra has also confirmed that cattle and pigs at another farm nearby have been slaughtered "on suspicion of infection".

A national movement ban - affecting cattle, sheep, pigs and other ruminants - has been imposed in England, while the European Union (EU) has banned livestock exports.

Prime Minister Gordon Brown said: "We will do everything in our power to get to the root of what has happened.

"The culling has already started. The protection zone is already in place."

Milton Park Farm is located about 10 miles away from the site of last month’s foot-and-mouth outbreak.

News of the latest case broke as animal markets were held across Devon.

Peter Kendall, president of the National Farmers' Union, said: "The confirmation of foot-and-mouth disease is a hammer-blow to the industry which has left livestock farmers stunned.

"Our main focus now must be on controlling and eradicating the disease as quickly as possible. Farmers must be extremely vigilant and biosecurity is of paramount importance.

"The imposition of movement restrictions is absolutely imperative to ensure the disease is stopped in its tracks."

Hilary Benn, Secretary of State for the Environment, added: "This is news that no one wanted to hear, least of all the farming industry.

"The immediate establishment of both a protection zone, with footpaths closed within it, and a national animal movement ban shows our determination to contain and eradicate this latest outbreak.

"Having spoken this morning to farming industry representatives, I know they share this view and the utmost vigilance is now needed from everyone."

Peter Ainsworth, Shadow Environment Secretary, blamed the latest outbreak on government complacency.

He said: "The government's shameful role in the causes of the original outbreak was bad enough; now it seems possible that, in their eagerness to put the issue behind them, they relaxed security measures too early. I fear that farmers may pay a heavy price for the government's complacency."
