Parma: The European Commission adopted Implementing Decision (EU) 2026/1944 this month after Germany notified a highly pathogenic bird flu outbreak at a poultry establishment in Lower Saxony, adding fresh protection and surveillance zones to the Union’s emergency measures framework just as the autumn migration season begins. The decision restricts movements of poultry, eggs and derived products from the affected area.
Timing gives the case weight beyond one German farm. Wild waterfowl carry H5 viruses south from breeding grounds each autumn, and the EU’s worst outbreak periods have consistently followed that migration.
The numbers from the last cycle explain the caution. Between 29 November 2025 and 27 February 2026, authorities across 32 European countries reported 406 outbreaks in domestic birds and 2,108 detections in wild birds. Wild bird detections ran three times higher than the same quarter a year earlier and almost five times higher than two years earlier.
The European Food Safety Authority, the European Centre for Disease Prevention and Control and the EU Reference Laboratory publish that monitoring jointly each quarter. Their assessment of how the virus reaches farms has stayed consistent.
On poultry farms, most infections stemmed from indirect contact with wild birds and spread from farm to farm was rare.
That finding shapes the policy. If wildlife contact drives introduction rather than farm-to-farm transmission, biosecurity on individual holdings matters more than movement controls between them, and housing orders become the primary defensive tool once migration peaks.
Spring brought relief without resolution. Between 28 February and 4 June 2026, 30 European countries reported 949 HPAI A(H5) detections, split between 186 in domestic birds and 763 in wild birds. Outbreaks in poultry stayed low outside a handful of countries. EFSA’s summary of declining detections across the EU set out the seasonal pattern.
One finding in that spring window broke new ground. Laboratories detected A(H9N2) virus of clade G5.5 in European poultry for the first time, a subtype long endemic in Asian flocks. Scientists also recorded serological evidence of past exposure in an apparently healthy dairy cattle herd in the EU, the first such signal in the bloc and a possible spillover from wild birds. Follow-up investigations continue.
Public health authorities keep the risk assessment unchanged. ECDC rates the risk from currently circulating clade 2.3.4.4b viruses as low for the general population in the EU and EEA, and low to moderate for people exposed through work to infected animals or contaminated environments.
Farmers face the commercial consequences regardless of that rating. A confirmed outbreak triggers culling, a ten-kilometre restricted zone and a trading halt that can idle a business for months. The EU co-finances compensation through the veterinary emergency fund, and the Commission released 14 million euros to Poland in July 2025 to reimburse farmers who lost flocks.
Producers heading into the autumn face a familiar checklist:
- Housing orders in high-risk zones once regional authorities trigger them
- Separation of poultry from open water and wild bird feeding areas
- Controlled access, disinfection points and dedicated clothing for staff and visitors
- Immediate notification of raised mortality to the competent national authority
Vaccination has moved from taboo to tolerated. France has vaccinated ducks since 2023, and the Commission has adjusted intra-Union trade rules to accommodate vaccinated flocks, though several member states still resist on trade grounds because third countries treat vaccination as a barrier to export certification.
The legal architecture sits in the Animal Health Law and the emergency measures the Commission updates outbreak by outbreak. Each new implementing decision amends the annex listing restricted zones, which is why decisions like 2026/1944 appear with little fanfare and considerable practical effect. The Commission maintains the consolidated picture on its avian influenza control measures page.
Germany’s zones will lapse if surveillance finds nothing further. The migration that starts now will decide whether they were the first case of the season or an isolated one.
