Avian Influenza Detected in Zeewolde

Within the 1-kilometer zone, there are 2 other poultry farms. These farms are sampled for the presence of the avian influenza virus and intensively monitored for 14 days. Within the 3-kilometer zone, 3 other poultry farms are screened by the NVWA. Within the 10-kilometer zone, there are 13 poultry farms.

A transport ban applies immediately throughout the entire 10-kilometer zone. This means that no birds, hatching eggs, and/or consumption eggs may be transported from locations with birds in this zone. A ban also applies to the removal of manure from birds and used litter. Other animals than birds and their products may be transported to and from locations with birds provided this is done according to the strict conditions of the hygiene protocol.

These measures are necessary to prevent spread to other parts of the country. The exact locations can be seen on the animal disease viewer of the Netherlands Enterprise Agency (RVO).

Since October 16, 2025, a national housing and screening obligation for avian influenza applies in the Netherlands. The housing obligation applies to all commercially kept birds. The screening obligation applies to non-commercially kept risk birds (for example, hobby chickens).

The NVWA conducts tracing investigations into risky contacts. This investigates whether products or poultry have been transported to and from this location in the period prior to the report. If necessary, additional measures will follow, such as extra sampling or blocking a risky contact company. These measures will be communicated via an update in this press release and through the online channels of the Ministry of Agriculture, Fisheries, Food Security and Nature (LVVN).
