Britain 'must avoid disease mistakes'

Special licences are already being prepared to allow healthy animals to start being moved from disease-free areas to abattoirs on Tuesday.

But the minister said there was little risk of these animals spreading the disease during transportation.

He warned stringent checks would be in place to ensure infected animals did not come into contact with healthy ones.

On Saturday, new cases were confirmed in Cornwall, Scotland, Durham, Cumbria, Lancashire, Oxfordshire, Tyne and Wear and Herefordshire.

Chief Veterinary Officer Jim Scudamore said most of the cases were in sheep or linked to sheep and the movement of animals.

He said the number of cases caused by airborne infection was pretty low and usually in pigs.

About 45,000 animals have now been slaughtered as a result of the outbreaks, including 6,300 animals which may have come into contact with infected livestock.

Mr Brown said the government was investigating how and why the disease entered the country and whether the control and enforcement procedures were adequate.

He said the pattern of trade across the UK and the role of markets in the spread of the disease was also under scrutiny.

But he added: "I'm very conscious that in 1967, in that outbreak they believed they had it under control, relaxed controls and then it broke out again."

"That is a mistake we cannot afford to make."

Efforts to control the spread of the virus have also led to further restrictions on the movement of people in the countryside.

Snowdonia National Park has been closed and walkers who break the entry ban face a £5,000 fine.

The Forestry Commission has closed 2.4 million acres of forests and woodland, including the New Forest in Hampshire.

Mr Brown backed calls from farmers' unions for people to avoid travelling around the countryside and visiting livestock farms - including politicians.

But the minister would not be drawn on whether the disease would have an impact on the date of the general election.

Mr Brown said he would answer questions relating to foot-and-mouth at Agriculture Questions in Parliament on Thursday.
