Florina study sharpens bovine tuberculosis risk picture in Greece

A newly published study is putting a finer point on bovine tuberculosis risk in Florina, a rural region of northern Greece where the disease continues to challenge cattle health programs. The paper, published September 19, 2026 in Animals, analyzes 30 tuberculosis skin test-positive herds and asks a practical question for field veterinarians: once a herd is identified, what does infection look like inside that herd, and which farm characteristics appear to track with higher positivity?

That question matters because bovine tuberculosis control in Greece sits within a long-running eradication framework rather than a one-off outbreak response. Greece’s national administrative guidance describes bovine tuberculosis eradication as a compulsory program applied across all cattle holdings through regional veterinary services. At the EU level, Greece is included among member states with an approved compulsory eradication program for infection with Mycobacterium tuberculosis complex in bovine populations, underscoring that this is an active surveillance and control issue, not a historical one.

The study itself centers on Florina, in Western Macedonia, an area with its own regional veterinary infrastructure and a history of livestock disease control activity. While the full article text was not directly retrievable through the search tool because of publisher rate limiting, the publication record confirms the study title, authors, journal, and publication date. From the abstract material provided and the indexed citation, the authors set out to characterize epidemiological features of bovine tuberculosis-positive herds in this higher-prevalence area and assess how apparent animal-level positivity for Mycobacterium tuberculosis complex infection relates to farm characteristics.

Even without a publisher press release or formal outside commentary, the study lands in a well-established evidence base. Reviews and recent field studies from other settings have repeatedly found that bovine tuberculosis risk tends to rise with factors such as older age, larger herd size, cattle movements, prior herd history, pasture exposure, and proximity to other infected premises. EFSA’s earlier disease assessment also noted that Greece remained a non-OTF, or not officially tuberculosis-free, member state and reported a low but slightly increasing herd prevalence in the years covered by that review. Those broader findings don’t substitute for the Florina data, but they do help explain why a localized within-herd analysis could be operationally useful. (pmc.ncbi.nlm.nih.gov)

Why it matters: For veterinarians, the practical takeaway is that herd-level surveillance only gets you so far. Once a herd tests positive, the next challenge is understanding how infection is distributed across animals and which management or demographic features are associated with heavier within-herd burden. That can shape decisions around follow-up testing intervals, culling strategy, movement restrictions, cleaning and disinfection advice, and conversations with producers about animal introductions and contact structure. In regions where resources are finite, better risk stratification can make eradication work more efficient. (mitos.gov.gr)

The public health angle also remains important. Bovine tuberculosis is a zoonotic disease, and Greece’s own eradication-program description explicitly ties control efforts to the production of safe animal products and protection of public health. For mixed-practice veterinarians and public veterinary services, that keeps bovine tuberculosis firmly in the One Health category, especially in rural areas where animal movement, wildlife interfaces, and farm-to-farm contact can complicate control.

What to watch: The next step is whether these Florina findings translate into action, such as more targeted surveillance in higher-risk herds, region-specific guidance for field veterinarians, or follow-up work validating which herd characteristics best predict heavier within-herd infection. If the full dataset shows clear associations, it could give Greek animal health authorities a more precise basis for prioritizing testing and control in one of the country’s known bovine tuberculosis pressure points. This final point is an inference based on the role of risk-factor studies in eradication programs, rather than a stated policy announcement. (mitos.gov.gr)
