Norfolk has eight of England's 11 bird flu cases

Two more cases of bird flu were confirmed on Tuesday

Norfolk now has eight of the 11 recently confirmed cases of bird flu in England.

The Department for Environment, Food and Rural Affairs (Defra) said the highly pathogenic avian influenza H5N1 virus was detected at a farm near Attleborough, and at a premises near Watton.

Two monitoring control zones of 3km (1.8 miles) and 10km (6.2 miles) radius have been put in place around the premises and all birds on the sites would be humanely culled.

Since the start of the week, cases of bird flu have also been confirmed in captive birds in Cranworth, close to Watton, Attleborough and Gayton.

On Friday, Defra announced Norfolk, Suffolk, Lincolnshire and parts of Yorkshire had been made subject to an Avian Influenza Prevention Zone (AIPZ), to mitigate the risk of further outbreaks.

It is now a legal requirement for all bird keepers in the areas to "mitigate the risk of further outbreaks of the disease", it said.

The UK Health Security Agency said bird flu was "primarily a disease of birds" and the risk to the general public was very low.
