Overview
- Germany’s animal health institute FLI reports 48 H5N1 outbreaks in commercial holdings since early September with more than 525,000 birds culled across ten federal states, and counts are still rising.
 - In Mansfeld‑Südharz, H5N1 was confirmed at a 40,000‑hen farm; a two‑tier 3 km/10 km sperrzone is now in force and poultry meat and eggs from Berga, Kelbra, Thürungen and Roßla may not be marketed.
 - Lower Saxony logged fresh cases including about 18,000 turkeys in Emsland, roughly 10,000 hens in Diepholz, and two Rotenburg Putenbetriebe (around 8,800 and 13,800 birds), with flocks culled and protection/surveillance zones set.
 - North Rhine‑Westphalia intensified measures as Kreis Wesel ordered the cull of roughly 18,000–18,500 birds in Kamp‑Lintfort after an H5 finding pending FLI subtype confirmation and established a provisional 10 km zone.
 - Containment is tightening nationwide with new stall orders and event bans in multiple counties; Brandenburg confirmed three more holdings and tallied heavy crane die‑offs, while Hesse extended housing rules across additional districts.
