A case of the highly pathogenic avian influenza (HPAI) H5N1 virus, otherwise known as bird flu, has been detected in England, according to the Department for Environment, Food and Rural Affairs (Defra).
The case, which was confirmed yesterday (Wednesday August 6) on a commercial poultry setup in Breckland, Norfolk, has triggered a 3km protection zone and a 10km surveillance zone around the property.
The government also confirmed that all poultry on the Attleborough premises will be humanely culled to prevent any disease-spread.
This marks the third confirmed case of the virus in the last seven days.
A separate case of bird flu was confirmed in Attleborough last week (Wednesday, July 30).
The most recent confirmed case was in Scotland, when the chief veterinary officer announced on Friday (August 1) that the disease was reported in Banff, Aberdeenshire, the first case in Scotland since March 2025.
Bird flu prevention
Defra advised bird owners to keep up-to-date with the virus and monitor the interactive bird flu map on the department’s website.
The virus, which affects poultry and wild birds, spreads through contaminated feed and water, or through birds’ droppings and saliva.
Infected birds show signs including: sudden death; a swollen head; closed and runny eyes; lack of coordination; tremors; dropping of the wings; dragging legs; breathing difficulties; fever; and significant reduction in egg production.
The government is also reminding people to register as keeper of birds within 30 days of taking on poultry or other captive birds, in accordance with the law.
Poultry should be kept away from wild birds; standing water or ponds should be fenced off; rodents and pests controlled; and housing cleaned and disinfected,
Poultry producers are also advised to use clean clothing and footwear, have footbaths available on farm, and limit and control access to the birds.
Defra has also reminded farmers that bird flu is a notifiable disease in poultry and any suspected cases on a farm should be reported in accordance with the law.
