Avian Influenza Detected in Nijkerk

Within the 1-kilometer zone around this newly infected location, there is 1 other poultry farm. This farm is being sampled for the presence of the avian influenza virus and intensively monitored for 14 days. Within the 3-kilometer zone, there are 5 farms screened by the NVWA. Within the 10-kilometer zone, there are 144 farms. Some of these farms are also located in the restriction zone around the infections in Terschuur on November 17 and November 23.

A transport ban applies immediately to the entire restriction zone. This means that no birds, hatching eggs, or consumption eggs may be transported from locations with birds in this zone. There is also a ban on 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 shielding obligation for avian influenza applies in the Netherlands. The housing obligation applies to all commercially kept birds. The shielding 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 notification. If necessary, additional measures will follow, such as extra sampling or blocking a risky contact farm. These measures will be communicated via an update of this press release and through the online channels of the Ministry of Agriculture, Fisheries, Food Security and Nature (LVVN).
