Farmers in Northern Ireland are advised to be alert following the detection of Shamonda virus in the Republic of Ireland.
Bovine samples from two farms in Co. Cork yielded positive results for Shamonda virus during testing at Animal Health Laboratories in Bandon, Co. Cork.
Department of Agriculture, Environment and Rural Affairs (DAERA) Minister Andrew Muir has appealed for vigilance.
The Shamonda virus is a midge-borne virus that mainly affects cattle but it has also been detected across Europe in sheep, goats, horses and alpacas.
Affected cattle may develop fever, diarrhoea, lethargy, reduced milk production and mild respiratory signs.
Abortions and congenital defects are also possible, similar to Schmallenberg virus.
The Shamonda virus is not a notifiable disease and is not subject to government disease controls.
There are no movement restrictions or impacts on trade and there is no known human health impacts associated with it.
There is also currently no vaccine or treatment available for Shamonda which emerged in western and central Europe this summer.
Minister Muir said: “The announcement by the Department of Agriculture, Food and the Marine of the presence of Shamonda virus is notable.
"Coming on the back of the emergence of bluetongue last year, which is another midge-borne virus, it is essential farmers and horse owners are alive to both viruses and familiarise themselves with the symptoms.
“Whilst there is no evidence of the virus in Northern Ireland, farmers and horse owners should remain aware of unusual illness in their animals and contact their private veterinary practitioner if they have concerns.”
