All poultry and captive birds in England must be housed from Monday (November 7) as the country faces its largest ever outbreak of bird flu.

The mandatory housing measure comes into force at 12.01am.

The new law means that all bird keepers must keep their birds indoors and follow stringent biosecurity measures to help protect their flocks from the disease, regardless of type or size.

The order will extend the mandatory housing measures already in force in the hot spot area of Suffolk, Norfolk and parts of Essex to the whole of England following an increase in the national risk of bird flu in wild birds to 'very high'.

Over the last year, the UK has faced its largest ever outbreak of avian influenza with more than 200 cases confirmed since late October 2021.

Since October 1 this year there have been 91 cases confirmed.

The UK Chief Veterinary Officer, Christine Middlemiss, said: "We are now facing this year, the largest ever outbreak of bird flu and are seeing rapid escalation in the number of cases on commercial farms and in backyard birds across England.

"The risk of kept birds being exposed to disease has reached a point where it is now necessary for all birds to be housed until further notice.

"Scrupulous biosecurity and separating flocks in all ways, from wild birds remain the best form of defence.

"Whether you keep just a few birds or thousands, from Monday, November 7 onwards you must keep your indoors.

"This decision has not been taken lightly, but is the best way to protect your birds from this highly infectious disease."

Evidence shows that housing birds reduces the risk of kept birds being infected with bird flu.

However, housing alone will not protect birds and all keepers must still follow the other enhanced biosecurity measures mandated by the Avian Influenza Prevention Zone (AIPZ) at all times to protect their flocks and prevent the risk of future outbreaks which is circulating in wild birds.

Housing combined with stringent biosecurity measures can provide even greater reduction in risk.

The AIPZ means that all bird keepers need to take extra precautions, such as restricting access for non-essential people on site, ensuring workers change clothing and footwear before entering bird enclosures and cleaning and disinfecting vehicles regularly to limit the risk of the disease spreading.

Biosecurity guidance and a biosecurity self-assessment checklist have been published by Defra to help all bird keepers in instigating and maintaining good biosecurity, which together with further updates on the latest avian influenza situation, can be found via GOV.UK/bird-flu

The addition of housing measures to the AIPZ already in force across England means all bird keepers across England must:

  • housing or netting all poultry and captive birds
  • cleanse and disinfect clothing, footwear, equipment and vehicles before and after contact with poultry and captive birds – if practical, use disposable protective clothing
  • reduce the movement of people, vehicles or equipment to and from areas where poultry and captive birds are kept, to minimise contamination from manure, slurry and other products, and use effective vermin control
  • keep records of mortality, movement of poultry and poultry products and any changes in production
  • thoroughly cleanse and disinfect housing on a continuous basis
  • keep fresh disinfectant at the right concentration at all farm and poultry housing entry and exit points
  • minimise direct and indirect contact between poultry and captive birds and wild birds, including making sure all feed and water is not accessible to wild birds
  • prevent access by poultry to ponds and watercourses and ensure that birds are kept in fenced or enclosed areas
