Avian Influenza Detected in Terschuur

Avian influenza has been detected at a laying hen farm in Terschuur, Barneveld municipality, Gelderland province. To prevent virus spread, approximately 62,000 hens are culled by the Dutch Food and Consumer Product Safety Authority (NVWA). There are 2 other poultry farms within 1 km, 11 within 3 km, and 182 within 10 km of Terschuur.

Transport Ban

A transport ban is immediately in effect throughout the entire 10-kilometer 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 bird manure and used litter, as well as other animals and animal products from farms with birds. These measures are necessary to prevent spread to other parts of the country.

The location of the 10-kilometer zone can be seen on the animal disease viewer of the Netherlands Enterprise Agency (RVO).

National Measures

Since October 16, 2025, a national housing and shielding obligation due to avian influenza has been in place 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).

Tracing Investigation

The NVWA is conducting 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 farm. These measures are communicated via updates in this press release and through the online channels of the Ministry of Agriculture, Fisheries, Food Quality and Nature (LVVN).
