The outbreak was detected at a farm in Biddinghuizen, about 70 kilometres (43 miles) west of Amsterdam, where about 180,000 ducks were put down together with another 10,000 within a one kilometre radius, the Dutch food and safety watchdog NVWA said.
Šobrīd tiek novērotas vēl trīs putnu fermas, kas atrodas trīs kilometru rādiusā ap minēto fermu, kas atrodas apmēram 70 kilometrus uz rietumiem no Amsterdamas, bet desmit kilometru rādiusā noteikts putnu gaļas un tās izstrādājumu transporta aizliegums.
