A dangerous strain of bird flu has been confirmed on a turkey farm in the UK – it was detected in more than 5,000 birds on a poultry farm near Louth in Lincolnshire, the Department for Environment, Food and Rural Affairs (Defra) said.

Public Health England (PHE) said the risk to the public is "very low" and that the infection would not affect supplies of the bird to consumers over Christmas.

It is the first confirmed case in Britain of the highly pathogenic H5N8 strain, which had already been circulating in countries across Europe, from Poland to France.

Birds on the farm which have not already died will be culled in order to prevent the disease spreading and a 3 kilometre protection zone has been put in place.

Chief veterinary officer Nigel Gibbens said: "Immediate steps have been taken to limit the risk of the disease spreading and all remaining poultry at the farm will be culled.

"Public Health England has confirmed that the risk to public health is very low and the Food Standards Agency has said that bird flu does not pose a food safety risk for UK consumers.

"Bird keepers should remain alert for any signs of disease, report suspected disease immediately and ensure they are maintaining good biosecurity on their premises. We are urgently looking for any evidence of disease spread associated with this farm to control and eliminate it."
