Restrictions have been placed around Chessington World of Adventure in Surrey - some 20 miles from the first outbreak of foot-and-mouth disease.

Officials at Defra announced that a 3km temporary control zone has been established as a precaution while tests are carried out.

The latest precautionary zone is outside the current surveillance zone.

It is understood that veterinary officials from Defra's Animal Health agency are checking for signs of possible infection in a sheep at the wildlife park.

This follows Defra's decision to place a dairy farm on the Romney Marshes close to the Kent coast between Hastings and Eastbourne under similar restrictions.

The 3km temporary zone around Stephen Furnival's farm, which has about 300 dairy cows.

The alert was raised when the farmer informed Defra vets of his concern of lesions in a batch of calves.

The results of these tests are expected later tonight or early tomorrow morning. However, it is thought that the virus has not spread to the Romney Marsh farm.

Both are precautionary measures following inconclusive assessments of clinical symptoms by Animal Health veterinary staff.

The national movement ban remains in place.

In addition, in the Temporary Control Zone, general licences will not apply for the movement of animals to slaughter and collection of dead animals from farms.
