Highly pathogenic avian influenza has been confirmed at a Dutch poultry farm, following the discovery last week of cases in two wild swans.
A cull will now take place of 35,000 birds at the farm in the village of Altforst, around 60 miles southeast of Amsterdam.
The government has not yet confirmed the strain of avian influenza. Controls were put in place last week, ordering farmers to keep all birds indoors. Authorities have also banned the transport of birds, eggs, or litter in the 10km zone around the affected farm.
In the UK, the avian influenza risk has been raised by Defra to medium.
