Birds will be culled at a commercial poultry premises in Co Tyrone following a suspected case of bird flu.
Disease control measures have been initiated by the Department of Agriculture, Environment and Rural Affairs following a suspect case of the notifiable highly pathogenic, avian influenza (HPAI), at the site near Pomeroy.
Agriculture Minister Andrew Muir said the suspected case was reported on 1 November and initial results suggested the presence of HPAI, so disease control measures were being introduced as a "precautionary measure".
Almost 16,000 birds were also culled at a site near Pomeroy earlier this year due to suspected bird flu.
