Bird flu restrictions have eased again in parts of Lincolnshire and Cambridgeshire, giving poultry keepers some breathing room after a bruising spring. In its latest update, Defra said the 3km protection zone and 10km surveillance zone around a second infected premises near Great Shelford in South Cambridgeshire were revoked on 19 May, while the surveillance zone around a second premises near Market Rasen in West Lindsey was revoked on 15 May. For farmers, smallholders and rural businesses, that is welcome news. But it is not an all-clear. Defra is still telling keepers across England to stick to tight biosecurity, check what zone they are in before moving birds or eggs, and make sure they have the right licence where one is needed.

Lincolnshire has been one of the counties carrying much of the pressure this season. Defra said that on 11 May the 3km protection zones around fourth and fifth infected premises near Gainsborough ended, with those areas then folded into the wider surveillance zone. A few days earlier, on 8 May, the protection zone around a second premises near Market Rasen also ended and moved into surveillance, after all poultry on the site were humanely culled. That sequence matters in places such as West Lindsey, where commercial units, small flocks and neighbouring farms often sit within a few miles of one another. Each change to a protection or surveillance zone affects daily decisions on movements, visitors, cleaning routines and whether trade can carry on as planned.

England's national housing measures were lifted on 9 April 2026, meaning many keepers were allowed to let birds outside again. Even so, Defra made clear that the wider avian influenza prevention zone still comes with mandatory biosecurity rules, and birds must still be housed if a premises falls inside an active protection zone or captive bird monitoring zone. For rural readers, that is the practical point. The end of housing rules does not mean the end of the work. Boots, wheels, sheds, feed stores and visitors all still matter. On mixed farms and backyard holdings alike, disease control is now as much about routine discipline as it is about the latest outbreak notice. Even where there is no zone on the doorstep, poultry keepers across the North will be watching these updates closely because the same rulebook applies nationwide.

The scale of the outbreak explains why officials are taking that line. Defra's season summary shows 79 confirmed HPAI H5N1 cases and one low pathogenic case in England so far in 2025-26. Across the UK, the total stands at 100 HPAI cases and one low pathogenic case, with the first cases of the season confirmed on 9 October 2025 in Northern Ireland, 11 October in England, 25 October in Wales and 12 November in Scotland. That does not reach the grim peak seen in 2022-23, when the UK recorded 207 HPAI cases, but it is still far above the six cases logged in 2023-24 and higher than the 82 recorded in 2024-25. Under World Organisation for Animal Health rules, the UK is not currently classed as free from highly pathogenic avian influenza.

The official risk picture is steadier than the raw case numbers might suggest, but it is not relaxed. Government assessments say the risk of HPAI H5 in wild birds in Great Britain is medium. The risk to poultry is judged low where exposure occurs, whether biosecurity is poor or strong, though uncertainty is higher where standards are weaker. For the public, the message from the UK Health Security Agency remains that bird flu is mainly a disease of birds and the risk to human health is very low. The Food Standards Agency says the food safety risk is also very low and that properly cooked poultry and eggs remain safe to eat. That will reassure shoppers, but it does little to ease the strain on producers dealing with movement rules, disrupted trade and the cost of outbreaks.

There are still plenty of rules to keep an eye on. Outside disease control zones, some bird gatherings can go ahead under general licence conditions, while others need a specific licence. Keepers of game birds, racing pigeons, birds of prey and backyard flocks are all covered by separate guidance, and anyone moving poultry, eggs, by-products or related material may need a movement licence depending on where they are and what they are doing. Vaccination is not the answer most keepers can turn to. In England, poultry and most captive birds cannot be vaccinated against bird flu. The exception is for eligible zoo birds, and even then only with authorisation from the Animal and Plant Health Agency. For most farms, the job remains the same: spot symptoms early, report quickly and do the hard, unglamorous biosecurity work every day.

The disease is not confined to farm gates. Defra is still asking people to report dead wild birds and not to touch or move sick or dead birds they find. Land managers and local authorities are also being pointed towards official posters and mitigation guidance as part of the wider response in the countryside. There is a legal duty around mammals too. Influenza of avian origin is notifiable in wild and kept mammals, and suspected cases must be reported immediately. For communities from Market Rasen to Great Shelford, the latest revocations are a step in the right direction. But across rural England, bird flu is still a live issue, and the message to keepers is plain enough: check your zone, keep standards tight and do not assume the worst is behind us.
