Avian Influenza (H5N1) Outbreak Widens Across Germany in Winter 2025/2026

Germany is facing a significant spread of the avian influenza virus H5N1 during the winter season of 2025/2026. Recent reports confirm outbreaks in several German states, leading to extensive culling and restrictions to control the virus’s expansion.

In Mecklenburg-Vorpommern, a confirmed outbreak affected approximately 40,000 broiler parent animals, resulting in the agricultural authorities setting up a protection zone around the farm. Similarly, in Oldenburg, Lower Saxony, an AI suspicion involving 8,500 turkeys was confirmed by the state laboratory to be the H5 virus, with preparations underway to cull the flock.

Jerichower Land in Saxony-Anhalt experienced a confirmed outbreak necessitating the culling of 30,800 hens. Other outbreaks have been reported in Kranenburg, North Rhine-Westphalia, with turkeys showing severe symptoms. Despite ongoing virus presence, some counties in Lower Saxony and North Rhine-Westphalia have already lifted stall bans imposed earlier to limit infections.

Cross-border concerns have emerged as well, with Poland reporting a major outbreak in a large poultry farm. In response, Polish authorities have proposed a pilot vaccination program focusing on laying hens, reflecting efforts to curb the virus in the region.

While control measures such as culling and protection zones are actively implemented, the virus remains a serious threat to Germany's poultry industry. Authorities continue to monitor affected districts closely to manage the spread.

The situation highlights the ongoing challenges posed by avian influenza during this winter, emphasizing the need for vigilance and coordinated efforts in affected regions and beyond.
