Bluetongue virus found in herd in Wexford

Irish agricultural authorities have confirmed the presence of bluetongue virus (BTV-3) in a cattle herd located in County Wexford, marking the Republic of Ireland’s first documented case. This development follows previous detections in Northern Ireland during December 2023, indicating a concerning pattern of viral spread across the region.

Minister for Agriculture Martin Heydon characterized the discovery as “unwelcome but unsurprising” given the virus’s progressive movement throughout Europe, Great Britain, and more recently Northern Ireland. The pathogen, transmitted primarily through midge bites, presents no direct risk to human health or food safety standards but poses significant threats to cloven-hoofed livestock including sheep, cattle, goats, deer, and camelids.

Clinical manifestations of BTV-3 infection range from oral and facial ulcerations, swallowing and respiratory complications, pyrexia, and lameness to more severe outcomes including fetal abnormalities and stillbirths. The current outbreak trajectory originated in the Netherlands during 2023, where it decimated tens of thousands of sheep before wind-borne midges carried the virus to southeastern England.

Minister Heydon noted that seasonal temperature declines may temporarily inhibit widespread transmission, but ongoing epidemiological investigations include enhanced sampling protocols to monitor viral dynamics. Agricultural representatives have expressed profound concern, with ICMSA President Denis Drennan describing the situation as “hugely worrying for the family concerned and the wider farming community.”

Authorities strongly recommend livestock producers consult with veterinary professionals regarding vaccination strategies tailored to their specific operational circumstances. While infection severity appears geographically variable with some animals demonstrating resilience or full recovery, the agricultural sector remains on high alert for potential expansion of the outbreak.
