More than 17,000 birds were destroyed to prevent the spread of low pathogenic avian influenza in the Netherlands.
Infected flocks are often destroyed although low pathogenic strains do not cause deaths. It is thought that low pathogenic strains can develop into highly pathogenic strains within flocks.
The outbreak took place in Deurne, Noord-Brabant and a 1-km restriction zone was immediately established in the area.
Authorities have already screened the three other premises within the 1-km zone.
