TFF News, 28 March 2026, Livestock
Vets and farmers are sounding the alarm as reports of bluetongue-related abortions and birth defects increase across UK farms. Concerns mount over whether current testing protocols are sufficient to detect and manage outbreaks. This surge in cases threatens livestock health and farm productivity, prompting calls for a reassessment of disease surveillance measures.
Bluetongue, a viral disease spread by midges, primarily affects sheep but can also impact cattle. While it rarely kills adult animals outright, it causes significant reproductive issues, including abortions and malformed offspring. Recent farm reports indicate a worrying uptick in these problems, signalling that the virus may be spreading undetected. Vets suggest that current testing arrangements might be inadvertently weakening efforts to monitor and control the disease.
Why the Concern?
The increase in bluetongue-related reproductive issues raises several critical questions: Why are abortions and birth defects rising now? How effective are current testing strategies? What risks do these outbreaks pose to farmers’ livelihoods? And crucially, what can be done to improve surveillance and response?
Current testing relies heavily on clinical suspicion followed by targeted sampling. However, many infected animals show mild or no obvious symptoms, meaning infections can slip through unnoticed. This under-detection hampers efforts to contain the virus before it impacts herd fertility and causes economic losses.
Bluetongue’s Impact on Farms
Bluetongue causes pregnant ewes and cows to abort or produce weak, malformed offspring, which severely affects flock and herd productivity. The loss of lambs and calves at birth reduces farm output and increases replacement costs. For many farmers, these setbacks come on top of already tight margins and fluctuating market prices.
Veterinary professionals report that more farms are experiencing these problems than in previous years. This suggests that bluetongue is becoming more widespread or that current control measures are insufficient. The disease’s seasonal nature, linked to midge activity, means outbreaks can flare unexpectedly, catching farmers off guard.
Testing and Surveillance Challenges
Vets warn that the current bluetongue testing regime may be unintentionally weakening overall surveillance. Testing is often only carried out when abortions or birth defects are already apparent, meaning early or subclinical infections remain undetected. This reactive approach limits the ability to track virus movement and implement timely interventions.
Improved surveillance could involve more routine and widespread testing, especially in high-risk regions during midge season. However, this approach would require additional resources and farmer cooperation. There is also debate about the best diagnostic tools and the feasibility of integrating bluetongue testing into broader herd health programmes.
Farmers’ Role and Industry Response
Farmers are at the frontline of detecting bluetongue impacts. Many are frustrated by the ongoing losses and the difficulty of securing timely veterinary advice and testing. They call for clearer guidance and support to manage the disease more effectively.
Industry bodies and government agencies acknowledge these concerns and are reviewing current bluetongue strategies. There is recognition that more robust surveillance, combined with farmer engagement and improved diagnostics, will be essential to curb the disease’s spread and mitigate its effects.
Looking Ahead
As bluetongue-related abortions and birth defects continue to rise, the livestock sector faces urgent questions about disease control and surveillance. The challenge will be balancing practical testing strategies with the need for early detection and prevention. Farmers and vets alike stress that without improved measures, bluetongue will remain a persistent threat to animal health and farm viability.
The coming months will be critical for assessing whether changes to testing protocols and surveillance can slow the disease’s advance. Meanwhile, farmers must remain vigilant and report any unusual reproductive losses promptly.
What TFF Members Are Saying
TFF members continue to track livestock prices amid these challenges while discussing disease impacts in the Thread 86: Beef / Lamb & Pig Price Tracker (Livestock & Forage). Many share firsthand experiences of bluetongue-related losses and debate the adequacy of current veterinary support and surveillance.
