From the Netherland’s Ministry of Economic Affairs we get confirmation that at least two wild ducks recently sampled in Utrecht province tested positive for HPAI H5 , although the N-type has not yet been established.
It is likely, given the recent outbreaks in the region, that they will test positive for H5N8.
This follows similar reports from Germany, Korea, and Japan and adds weight to the notion that the recently emerged H5N8 virus is being transported across long distances by wild and migratory birds.
First the announcement, then some excerpts from a letter from the Ministry on the state of play and the investigation into the possible cause bird flu outbreak.

State of bird flu Zoeterwoude
On 30 November. Was established on avian flu in a legpluimveebedrijf Zoeterwoude. This company is therefore eliminated. Research has now determined that the bird flu concerns highly pathogenic H5N8 type.
In the area with a radius of 1 km around the infected holding is still one other poultry. As a precaution, it was decided to eliminate this business preventively.
This involves a company with about 50,000 broilers. Between 1 km and 10 km area are 3 other poultry farms. Two companies is currently no poultry. The other company has been inspected and samples taken to be examined.

The investigation is continuing.
In addition, research has been done on the introduction of the virus on the different companies. It is based on all available information, the most likely that there are three separate introductions of the bird flu virus occurred in the areas Hekendorp, Ter Aar and Kamperveen. this is shown include analysis of the Central Veterinary Institute (CVI), part Wageningen UR, how the viruses that are found on the infected companies genetically similar.
