Ireland is stepping up warnings on gov.ie as bluetongue virus remains a serious concern for livestock owners in 2026. With confirmed BTV-3 detections and growing disease activity in Great Britain and across Europe, farmers are being urged to act early, watch for symptoms, and speak to their veterinary practitioners about vaccination.
The latest update from the Department of Agriculture, Food and the Marine shows that bluetongue has been detected in parts of Ireland following extensive testing of cattle blood samples collected for other disease surveillance purposes. Cases have been identified in Wexford, Wicklow, Laois, Louth, Monaghan, Kildare, Cork and Tipperary, highlighting why gov.ie guidance is now central for herd and flock planning.
gov.ie Bluetongue Virus Update: What Farmers Need to Know
Bluetongue is a notifiable viral disease that affects ruminants and camelids, including:
- Sheep
- Cattle
- Goats
- Deer
- Llamas and alpacas
The disease does not pose a public health risk. It does not affect human health, and meat and dairy products remain safe. However, it can have major consequences for animal welfare, farm productivity, and livestock trade.
The Department of Agriculture, Food and the Marine has also noted that movements of livestock to certain EU member states and third countries may be affected following Ireland’s loss of BTV-free status. While meat and dairy exports continue without implications for the EU, UK and most international markets, live animal trade conditions may vary depending on destination rules.

How Bluetongue Spreads Across Ireland and Europe
Bluetongue virus is mainly spread by infected biting midges. These insects become active during warmer months, making the period from spring through autumn the highest-risk window. Changing weather patterns and milder winters may also extend the transmission season.
Animals can also become infected through:
- Infected germinal products such as semen and embryos
- Biological materials including blood
- Transmission from infected pregnant animals to unborn offspring
This wider European picture matters. BTV-3 has spread rapidly across mainland Europe and Great Britain since late 2023, while other strains including BTV-1, BTV-4 and BTV-8 are still circulating. That makes ongoing monitoring through gov.ie, the Department of Agriculture, Food and the Marine, and agencies such as the Environmental Protection Agency (EPA) and Health Service Executive (HSE) important in the broader public information landscape, even though bluetongue itself is not a human health issue.
Signs That May Indicate Bluetongue
Sheep are more likely than cattle to show obvious clinical signs, and severe outbreaks can result in high mortality. Farmers should watch for:
- Fever
- Loss of appetite
- Reduced milk yield
- Lethargy
- Mouth, eye or nose lesions
- Swelling of the face, lips or tongue
- Drooling or increased salivation
- Nasal or eye discharge
- Lameness or swollen legs
- Abortions, stillbirths or deformities
Vaccination, Reporting and Trade Guidance
Vaccination against bluetongue serotype-3 has been permitted in Ireland since 1 January 2026 for cattle and sheep. Farmers considering vaccination should consult their private veterinary practitioner because immunity takes time to build—around six weeks in cattle and three weeks in sheep.
If bluetongue is suspected, animals should be isolated indoors immediately and the case reported without delay to the local Regional Veterinary Office or the national disease emergency hotline. This reporting duty is critical and aligns with the wider compliance culture familiar across Irish regulators, from the Revenue Commissioners to the Workplace Relations Commission (WRC) and An Garda Síochána, where prompt reporting protects the wider public interest.
Conclusion
The key message from gov.ie is clear: vigilance, early reporting and timely vaccination planning are essential as Ireland faces an elevated bluetongue threat in 2026. For livestock owners, staying informed through official gov.ie updates and veterinary advice is the best way to protect animal health, limit farm losses and manage trade disruption.
