    LP H7N7 bird flu in Barneveld


    News item | 12-03-2015

    In Barneveld (Gelderland) in a poultry farm with a total of around 30,000 laying hens bird flu (avian influenza, AI) had been detected. This company has free range chickens. Unlike the outbreaks in November last year, it's probably a mild H7 variant. Further analysis by the CVI (Central Veterinary Institute) should reveal this. It is expected that the results of this analysis are available tomorrow. Writes Dijksma Secretary of Economic Affairs in a letter to parliament.

    Because a low pathogenic (mild) H7 variant can mutate to a highly pathogenic (highly contagious and deadly for chickens) variant, the infected farm is cleared as soon as possible. This is based on European rules. Depopulation is by the Dutch Food and Consumer Product Safety Authority (NVWA).

    Movement ban

    From Thursday, March 12th at 14:30 applies in an area of ​​over one kilometer around the infected holding in Barneveld a ban on transporting poultry, eggs, poultry manure and used bedding. Within this area are 17 other poultry farms. These companies are sampled and tested for avian influenza. Also in this area a 1 kilometer ophok- and cover requirement for commercial poultry. The measures apply to three weeks.

    Update March 12, 2015, 16:53: Analysis has shown by CVI that at the poultry farm in Barneveld confirmed outbreak of bird flu (avian influenza AI) for the mild variant H7N7.
