All 76,000 hens on a poultry farm in Schore in Zeeland have been killed following an outbreak of bird flu, the farm ministry has confirmed.

No other farms are affected by the cull but five farms within a 10 kilometre radius of Schore have been banned from moving birds, eggs and manure while checks are carried out.

The outbreak is the second in two days. On Monday, the virus was identified on a poultry farm in Lunteren in Gelderland, in the heart of the Dutch egg industry.

So far over 3.5 million birds have been culled since the outbreak began last October and the disease has been identified on 54 farms.

The Netherlands has some 1,700 poultry farms, half of which produce eggs.
