Bird flu is back, and the migrating birds are still arriving
What happened
Avian influenza has returned to the UK, and Defra is asking every bird keeper to tighten up. In a release published on 9 October 2026, the Department for Environment, Food and Rural Affairs urged all bird keepers to review and strengthen their biosecurity. That means poultry farmers, but it explicitly also means people who keep pet birds and a few hens in the garden. The trigger was a case of Highly Pathogenic Avian Influenza (HPAI) confirmed in Scotland the previous week. The wider picture is that bird flu is circulating in wild birds across Europe and spilling over into poultry and other kept birds. Defra says the risk of incursions is set to increase as migratory wild waterfowl return to the UK to overwinter. That is the key bit of timing. Ducks, geese and swans are arriving now for the winter. Some carry the virus. The risk curve goes up through autumn rather than down. Christine Middlemiss, the UK's Chief Veterinary Officer, was direct about the obligation: "All bird keepers must ensure ongoing robust biosecurity to protect the health and welfare of their birds." She added: "I urge all bird keepers to remain vigilant, monitor their birds closely and report any suspicions of disease to APHA." APHA is the Animal and Plant Health Agency. There is also money attached for keepers in England. Eligible poultry keepers can access a £430 funded Poultry Biosecurity Review. It includes a vet visit, a written report and tailored recommendations, and keepers can choose their own vet. It is part of the government's Animal Health and Welfare Pathway.
Why this matters
If you keep six hens at the bottom of the garden, it is tempting to assume this is a story about big commercial farms. It is not. A garden flock sits in exactly the spot where the virus moves from wild birds into kept ones. An open run, a feeder that wild birds can reach, a pond that attracts ducks: these are the bridges. Small flocks are not a smaller version of the problem. They are often the first step in it. There is a hard welfare reality behind this too. Highly pathogenic avian influenza is usually fatal to the birds that catch it, and controlling an outbreak means culling. Good biosecurity is not paperwork. It is the thing that stops a flock being destroyed. For everyone else, bird flu shows up in two familiar ways. It affects the price and availability of eggs and poultry when large numbers of birds are lost. And it is the reason free-range birds are sometimes housed indoors, which changes how eggs can be labelled. It also affects how you should behave on a walk. Dead wild birds, particularly waterfowl and birds of prey, are not something to move or handle. Reporting them is genuinely useful, because wild bird surveillance is how the spread gets tracked. The honest framing is this: bird flu is now a seasonal feature of British autumn and winter, like flu in people. The work is routine rather than dramatic, and it has to actually be done.
What the evidence actually says
It is worth being careful about what Defra's announcement did and did not say, because bird flu generates a lot of loose talk. Defra's release did not assign a formal risk level. What it said is that the risk of incursions is set to increase as migratory wild waterfowl arrive. The risk level for Great Britain is set separately and updated as the situation changes, so the current official level is worth checking directly rather than assuming. The release also did not impose new legal requirements. It recommended measures. A housing order, which legally requires birds to be kept indoors, is a separate step that government can take in response to the picture on the ground. At the point of this announcement, keepers were being urged to strengthen biosecurity, not ordered to house their birds. That can change, which is why keeping an eye on Defra updates matters. The measures Defra recommends are unglamorous and practical: keeping areas clean, controlling rats and mice, cleaning footwear, protecting feed and water from wild birds, fencing outdoor areas, limiting access to ponds, and keeping ducks and geese apart from other poultry where possible. There is a reason those specific items appear. The virus travels in droppings and contaminated material. Rodents and dirty boots move it around. Shared feed and water are where wild and kept birds meet without ever being in the same place at the same time. On human health, the Defra release did not address risks to people. That absence should not be read either as reassurance or alarm. The settled position from health authorities is that avian influenza is primarily a bird disease and the risk to the general public is considered very low, while people in close contact with infected birds face more risk and are advised accordingly. For current human health guidance, UKHSA rather than Defra is the right source. There is one more thing the evidence supports: reporting works. Surveillance is how outbreaks are found early, and early is the only time control is cheap.
Practical advice
If you keep any birds, including a few hens or pet birds, do these things. Keep feed and water where wild birds cannot reach them. This is the highest-value change most small keepers can make, and it costs very little. A covered feeding area beats an open one. Fence outdoor areas and limit access to ponds. Standing water attracts exactly the wild birds that carry the virus. Keep ducks and geese apart from other poultry where you can. They can carry infection while looking well. Clean your footwear before and after going into the bird area, and keep a pair of boots that only ever go in there. Use a disinfectant foot dip and change it regularly. Control rats and mice, and keep the area tidy. Rodents spread contaminated material around. Monitor your birds closely. Sudden deaths, a drop in egg laying, swollen heads, breathing difficulties, or birds going quiet and off their food are all worth taking seriously. Report suspicions of disease to APHA. Do not wait to be certain. In England, Wales and Scotland the Defra rural services helpline is 03000 200 301. In Wales, contact APHA on 0300 303 8268. In Northern Ireland, contact DAERA. If you keep poultry in England and are eligible, look into the £430 funded Poultry Biosecurity Review. A vet visit plus a written plan, funded, is a good offer to leave unclaimed. Register your birds. Keepers are required to register poultry, and registration is what allows you to be contacted quickly if an outbreak happens nearby. For everyone, keeping birds or not: do not touch or move dead or visibly sick wild birds. Report them to the Defra helpline on 03459 33 55 77. Keep dogs on leads near large groups of wild birds, especially waterfowl. And on food: properly cooked poultry and eggs remain safe to eat. Bird flu is not a reason to change what is on your plate.
What to know
Defra urged all bird keepers on 9 October 2026 to review and strengthen biosecurity after a case of Highly Pathogenic Avian Influenza was confirmed in Scotland the week before. The virus is circulating in wild birds across Europe and spilling into kept flocks. Risk is rising now, not falling, because migratory wild waterfowl are returning to the UK to overwinter. The advice applies to pet bird keepers and garden flocks as much as to commercial farms. Practical measures: protect feed and water from wild birds, fence outdoor areas, limit pond access, separate ducks and geese from other poultry, clean footwear, control rodents and keep areas clean. Chief Veterinary Officer Christine Middlemiss asked keepers to remain vigilant, monitor birds closely and report any suspicion of disease to APHA. Eligible poultry keepers in England can get a £430 funded Poultry Biosecurity Review including a vet visit. Defra's release recommended measures rather than imposing new legal requirements, and did not set a formal risk level. Both the official risk level and any housing order can change, so check Defra updates during the season. Properly cooked poultry and eggs remain safe to eat.
