Sixteen thousand birds are to be culled as another case of suspected bird flu is investigated in a commercial poultry flock in Northern Ireland.
Stormont's Agriculture department confirmed test results indicated the presence of a highly pathogenic strain of the disease.
Restrictions have been put in place near the premises in the Pomeroy area of Co Tyrone.
Agriculture Minister Andrew Muir said all bird owners should comply with a recent housing order imposed on both sides of the border.
"This suspected incursion following the recently confirmed case in Dungannon, Co Tyrone, reinforces that we cannot afford to be complacent. It is imperative that all bird owners adhere to stringent biosecurity measures to protect their flock and report any suspicious cases immediately."
CVO Brian Dooher added: "The current disease control measures have been introduced to limit any potential spread of the disease. I urge all bird keepers, whether commercial or backyard, to maintain high biosecurity standards and fully comply with all requirements that have implemented to control this devastating disease."
Last weekend the first case of bird flu in a commercial flock was discovered in an egg laying facility outside Dungannon.
Sixty-four thousand birds were destroyed.
The disease was also confirmed in a captive flock near Magherafelt on 13 February.
