Netherlands on Saturday destroyed some 190,000 ducks at six forms, following an avian flu outbreak, the country's first cull of an epidemic sweeping northern Europe.
The outbreak of avian flu, primarily the highly pathogenic H5N8 strain, has been reported in Denmark, Finland, Germany and Sweden over the past week.
Dutch authorities did not say what strain of the virus had been discovered at a poultry farm in the village Biddinghuizen in the east of Amsterdam.
The Officials said they were checking for bird flu at farms within three kilometers of the original site and imposed a ban on transporting poultry products within a 10-km (six-mile) radius.
Netherlands is the world's second largest agricultural exporter, and it has more than 100 million pigs, hens, cows and sheep on high-intensity farms. The density makes the animals more vulnerable to disease outbreaks.
