Two more suspected cases of Bluetongue have been identified in Northern Ireland.
It was found in two cows on a farm near Bangor, Co Down.
It is the third time the disease, which is spread by biting midge, has been discovered.
The Bangor farm is in the same general area as the other two cases, and close to the where the outbreak was first confirmed late last month.
Forty-four confirmed cases were later established in that original herd of cattle.
Due to the proximity, Stormont's Agriculture Department has decided there is no need to extend the existing 20km control zone.
"The emergence of another suspect case is disappointing but not surprising given the scale of the surveillance testing that has taken place following the outbreak near Bangor," said Agriculture Minister Andrew Muir.
Farmers have been urged to remain vigilant for the symptoms of the disease which can affect cattle, sheep and goats.
Northern Ireland's Chief Vet has urged farmers to speak to their local vet should they have any concerns.
"While we remain hopeful that the winter will limit the ability of midges to further spread the disease, keepers who suspect an outbreak should report any symptoms immediately to their vet or local Divisional Veterinary Office," they said.
The area around the three farms is now being treated as a single unit for the purposes of restrictions that apply to livestock movements.
It covers a large area on both sides of the Ards peninsula in Co Down and a smaller part of south Co Antrim.
