Avian influenza (bird flu) in winter 2016 to 2017
The latest situation on avian influenza (bird flu) in the UK and advice on how to reduce the risks.
Avian influenza (bird flu) is a disease of birds. The H5N8 strain of the disease has been found in the UK in farmed and wild birds since December 2016.
A 3km protection zone and 10km surveillance zone are currently in place around 2 premises in Thornton, Wyre, Lancashire.
If you keep poultry and captive birds
H5N8 avian flu remains a threat to poultry and kept birds across the UK and keepers must comply with strict disease prevention measures.
An Avian Influenza Prevention Zone is in place across England. It applies to everyone who keeps poultry or captive birds. This means all keepers - whether they have commercial flocks or a few birds in their back garden - must follow strict rules on biosecurity.
These include minimising your movement in and out of bird enclosures, cleaning footwear, keeping areas where birds live clean and tidy and feeding birds indoors.

Read detailed advice about the Prevention Zone requirements (PDF, 12 pages).
Based on the latest risk assessment, the Chief Vet has confirmed that we expect to lift the existing Avian Influenza Prevention Zone on 15 May 2017 and replace it with a new Prevention Zone that will apply only to certain areas of Lancashire, Cumbria and Merseyside. After that date, keepers within the new Prevention Zone covering the districts of Barrow-in-Furness, South Lakeland, Lancaster, Blackpool, Wyre, Fylde, Preston, Sefton, West Lancashire, South Ribble and Chorley will still be required by law to follow specific disease prevention measures to reduce the risk of infection from wild birds; keepers outside the new Prevention Zone should continue to follow industry best practice on biosecurity.
A ban on poultry gatherings remains in place across the UK. This applies to birds including chickens, turkeys, ducks and geese, and restricts events such as livestock fairs, auctions and bird shows. We plan to lift this ban in England on 15 May 2017, except for gatherings within, and poultry coming from, certain areas of Lancashire, Cumbria and Merseyside. This will mean that most poultry gatherings can then resume, subject to some additional identity and health checks and biosecurity measures.
Advice on rearing game birds and shooting while the Prevention Zone is in force is available from The National Gamekeepers Organisation.
All disease control measures are kept under review based on the latest scientific evidence and veterinary advice.
Welfare of housed birds in warm weather
If your birds are housed it is especially important to keep a close eye on them in warmer weather to ensure they remain comfortable and healthy.
Check them regularly and ensure they have enough water and sufficient ventilation. You should monitor the maximum temperature and take action if it significantly exceeds 21ºC for adult birds or around 13ºC for adult ducks.

Free range status
All egg producers in England can now let their birds outside provided they observe strict disease prevention measures. Keepers can sell products as free-range if they come from birds which meet all the free-range requirements.
Reporting suspicion of disease in your poultry
For advice and guidance on what to do if you keep poultry or to report suspicion of disease in animals, call the Defra Rural Services Helpline on 03000 200 301 or read our detailed guidance on avian influenza.
Reporting dead wild birds
Members of the public should report dead wild birds - such as swans, geese, ducks, gulls or birds of prey - to the Defra helpline on 03459 33 55 77. Defra will then collect some of these birds and test them to help us understand how the disease is distributed geographically and in different types of bird.
Cases of avian influenza since December 2016
The H5N8 strain of the disease has been confirmed at farms in Northumberland, Suffolk, Lancashire and Lincolnshire, and in backyard flocks in North Yorkshire and Carmarthenshire.
Where avian influenza has been confirmed, we put restrictions around the site - a 3km Protection Zone and a 10km Surveillance zone - to limit the spread of disease, and we investigate the source of the infection.
As well as being found in poultry, the same strain of the virus has also been found in wild birds in England, Scotland and Wales. We publish a list of cases where we find avian influenza in wild birds.
We publish details of the situation across Europe in the latest veterinary outbreak assessment.
