Bird flu has been found on two turkey farms in Norfolk, the UK government confirmed over the weekend.
The "highly pathogenic" H5N8 strain of avian flu was found on Friday at a farm near Attleborough then at another farm on Saturday near King's Lynn.
Exclusion ZonesThe National Farmers Union (NFU) said three-kilometre protection and 10-kilometre surveillance zones have been set up around both the affected Norfolk turkey farms, where the names and addresses of visitors to premises where birds are kept and the movement of eggs and poultry have to be recorded (pdf).
The Norfolk H5N8 cases follow outbreaks at several other sites across England in November: one at a site in Cheshire, one in Herefordshire, one in Gloucestershire, one in Leicestershire, and one in North Yorkshire. The strain was also found at a second site in North Yorkshire on Dec. 1.
To curb the spread, birds were culled at each location where H5N8 was detected.
"In each case, Defra has acted quickly to cull affected birds and to introduce movement restrictions to limit the risk of the disease spreading," Defra said.
For large farms, in particular, requirements are around cleaning and disinfection of clothing, vehicles, and equipment, limiting non-essential people's access to sites, and workers changing clothing and footwear before going into bird enclosures.
Defra called on bird keepers and the public to report any dead wild birds they see to the Defra helpline on 03459 33 55 77 (option 7), and all keepers should report suspicion of disease to the Animal and Plant Health Agency (APHA) on 03000 200 301.
