Avian Influenza Detected in Drogeham

Within the 1-kilometer zone, there is one other poultry farm where avian influenza was detected on Friday, November 7, and which has since been culled. Within the 3-kilometer zone, there are 3 other poultry farms. These farms were screened by the NVWA last week and will be monitored for the next 14 days. Within the 10-kilometer zone, there are 26 poultry farms. The 10-kilometer zone roughly corresponds to the zone established on November 7.

A transport ban applies 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 manure from birds and used litter, as well as other animals and animal products from farms with birds. These measures are necessary to prevent the 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).

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

The NVWA is conducting tracing investigations into risky contacts. This investigates whether products or poultry have been transported to or 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 announced via an update in this press release and through the online channels of the Ministry of Agriculture, Fisheries, Food Security and Nature (LVVN).
