Rising costs and challenges in eradicating bovine TB persist

Bovine tuberculosis (TB) has become a significant concern for Irish agriculture, with current herd incidence at its highest in 15 years. The disease, caused by the bacterium Mycobacterium bovis, poses substantial challenges to farmers and the national economy.

Historical Context

Bovine TB has been a persistent issue in Ireland for decades. The eradication program began in 1954 when a significant portion of the national herd was affected. Despite efforts to control the disease, including compulsory testing and removal of infected animals, the incidence of TB has recently surged. In 2016, Ireland recorded a historic low incidence rate of 3.27%, but by 2024, this figure had risen to 6.04%.

Economic Impact

The financial burden of bovine TB on Ireland is substantial. The disease is projected to cost the country approximately EUR 130 million this year, with estimates reaching EUR 170 million by 2026 if current trends continue. Farmers face significant expenses related to testing and labor, with the Irish Farm Accounts Co-operative reporting costs of EUR 151.5 million in 2024 alone.

Challenges in Eradication

Several factors complicate the eradication of bovine TB. The disease can remain dormant in animals, making detection difficult. Additionally, the movement of cattle between farms and the interaction with wildlife, such as badgers and deer, contribute to the spread. Unlike New Zealand, where larger farm holdings limit cattle movement, Ireland's smaller farms facilitate more frequent animal transfers, complicating containment efforts.

Proposed Measures

In response to the crisis, the Department of Agriculture is considering new measures, including the publication of TB history for cattle sold at marts. This aims to provide transparency for buyers but has sparked debate about its impact on farmers' reputations. The absence of an effective vaccine further complicates eradication efforts, as current vaccines interfere with TB testing.

The road to eradicating bovine TB in Ireland remains challenging, requiring continued research, innovative strategies, and substantial funding to reverse the current trend.
