Bird flu prevention zone declared across England as farmers called upon to stop disease spreading

A bird flu prevention zone has been declared across England as all farmers are told to cover ponds in netting to prevent infected birds landing. The move, announced by the Government's chief veterinary officer Nigel Gibbens, means all poultry and bird keepers in England have to follow strict measures to protect their livestock from the disease.It comes as 13 dead wild birds were confirmed to have the virus in Warwickshire, following the discovery of the disease in wild birds in Dorset, where a total of 31 infected birds have now been identified.
