Avian influenza found in Friesland

Avian influenza has been detected on a poultry farm in Tzum (Friesland) with around 9000 laying hens. The farm has one housing unit with an outdoor run. It is thought most likely to be the mild H7 strain of influenza.

A low pathogenic H7 strain can mutate to a high pathogenic strain that is highly contagious and fatal for chickens. In either case preventative slaughtering must be carried out on the farm. This will be done by the Dutch Food and Consumer Product Safety Authority (NVWA) in line with European legislation.

Measures

As of Saturday 3 August 2013 at 09.00 hours, a movement ban applies for poultry, eggs, poultry manure and used litter in a zone of more than 1 kilometre around the farm. There are no other poultry farms within this area.
