Ireland’s livestock sector is being urged to stay alert as gov.ie updates farmers on the growing risk from bluetongue virus serotype 3 (BTV-3). The latest guidance from the Department of Agriculture, Food and the Marine outlines where cases have been detected, how the disease spreads, and what herd and flock owners should do now to protect cattle and sheep.
According to the latest official update, confirmed BTV-3 cases in cattle and sheep have been identified in several counties, including Wexford, Wicklow, Laois, Louth, Monaghan, Kildare, Cork and Tipperary. The warning comes as infections have also increased in England since July 2026, with reports of significant clinical signs in affected animals.
gov.ie bluetongue update: what farmers in Ireland need to know
The gov.ie publication makes clear that bluetongue is a notifiable viral disease affecting ruminants and camelids. Sheep, cattle, goats, deer, llamas and alpacas can all be infected, though sheep often show the most obvious symptoms.
The disease does not pose a public health risk. Meat and dairy products remain safe, an important reassurance for consumers, the agri-food sector, and export markets monitored by agencies such as the Revenue Commissioners and the Department of Agriculture.
However, bluetongue can have serious farm-level and trade consequences, including:
- Reduced milk yield and production losses
- Illness and possible deaths in livestock
- Movement restrictions for certain live animal exports
- Certification and compliance issues for some international markets
How bluetongue spreads
BTV is mainly transmitted by infected biting midges. These insects are active during warmer months, traditionally from April to November, though milder weather linked to Climate Action concerns may extend the transmission season. The virus can also spread through infected germinal products, blood, and from pregnant animals to unborn offspring.

Symptoms, vaccination and reporting suspected cases
The gov.ie guidance says farmers should watch closely for signs such as fever, loss of appetite, swelling of the face or tongue, mouth lesions, drooling, nasal or eye discharge, lameness, lower milk output, and reproductive problems including abortion or stillbirth.
If bluetongue is suspected, livestock owners should act immediately:
- Isolate the affected animal indoors
- Contact a private veterinary practitioner
- Report the suspicion without delay to the Department of Agriculture, Food and the Marine
This kind of rapid disease reporting is central to Ireland’s wider animal health system across gov.ie, working alongside public bodies connected to Health, Social Protection, Local Government and Heritage, and emergency coordination structures.
Vaccination now part of the 2026 response
Vaccination against bluetongue serotype 3 has been permitted in Ireland since 1 January 2026 for cattle and sheep. Farmers are being encouraged to speak with their vet about vaccinating before peak midge activity. Full immunity takes around six weeks in cattle and three weeks in sheep after vaccination.
The minister has also confirmed that bluetongue vaccination is included as an option under the 2026 beef and sheep welfare schemes, a move relevant for the wider Agriculture, Finance, and Enterprise, Trade and Employment landscape.

Trade, movement rules and the wider Ireland outlook
There has been some progress for cross-border farming activity, with cattle and sheep movements for production and breeding between Ireland and Northern Ireland having recommenced on 6 March 2026. At the same time, the loss of Ireland’s BTV-free status may affect livestock movements to some EU member states and third countries.
For many exporters, there are no implications for meat and dairy trade to the EU, UK and most global markets. Still, farmers and traders should check the latest certification requirements through official channels including gov.ie.
In short, the latest gov.ie bluetongue advisory is a clear call for vigilance: know the symptoms, discuss vaccination with your vet, and report concerns quickly. For Irish farmers, early action remains the best defence against wider disease spread and trade disruption.
