NI farmers warned over rising bluetongue threat

Northern Ireland farmers are being warned to remain vigilant after bluetongue serotype 3 (BTV-3) was detected in the Republic of Ireland, bringing the livestock disease closer to the border than ever before.

Eight cases have been recorded this season across Wexford, Wicklow, Kildare and Louth, while the number of affected premises in Great Britain has risen to 1,753 on Wednesday (23 September).

These include 1,513 premises in England, 207 in Wales and 33 in Scotland. A further 1,287 potential cases are under investigation after suspicious clinical signs were reported.

No cases have yet been confirmed in Northern Ireland, with several suspected cases reported in recent weeks ruled out following laboratory testing.

Cases expected

Department of agriculture, environment and rural affairs minister Andrew Muir said the spread of disease in Britain and Ireland, combined with more severe clinical signs, was concerning.

“While no cases of bluetongue have been detected in Northern Ireland during this season, it is possible the disease, which affects fertility and overall productivity on farms, could already be present in herds without animals exhibiting noticeable signs at this stage.

“As a result, my officials and I believe there is a strong possibility that clinical cases will emerge over the next month.”

Bluetongue poses no risk to public health or food safety, but can cause significant production and welfare problems in affected livestock.

Signs can include fever, sores or ulceration around the nose, eyes and mouth, breathing difficulties, reduced appetite and lethargy, alongside abortion, stillbirths and birth deformities.

Vaccination encouraged

Mr Muir urged farmers to report suspicious symptoms promptly and consider vaccination.

“BTV-3 vaccination remains the only preventative tool to help reduce the impact of this disease. It takes approximately six weeks for cattle and three weeks for sheep to develop full immunity following vaccination,” he said.

Surveillance is continuing at abattoirs, alongside post-import testing of susceptible animals brought in from mainland EU countries.

“Safe and responsible sourcing of animals remains of paramount importance,” he added.

Suspected cases should be reported immediately to Daera on 0300 200 7840 or through a local Daera direct regional office.
