Report: Economic Impact of Bovine Tuberculosis (bTB) in the United Kingdom

Bovine tuberculosis (bTB) is a significant concern for the United Kingdom’s agricultural sector, with profound economic implications. This report aims to provide a concise overview of the economic impact of bTB, highlighting the financial burdens imposed on farmers, the industry, and the wider economy.

  1. Losses in the Agricultural Sector: The presence of bTB leads to substantial economic losses within the agricultural sector. These losses stem from various factors, including reduced productivity, increased management costs, and animal culling. It is estimated that bTB-related costs in the UK agricultural industry amount to approximately £100 million per year.
  2. Testing and Treatment Expenses: The government and farmers invest significant resources in testing and diagnosing bTB cases and implementing subsequent treatment measures. The costs associated with testing, laboratory analysis, veterinary services, and medication can place a considerable financial strain on individual farmers. Farmers spend approximately £3,000 to £6,000 per reactor animal.
  3. Compensation and Animal Value: Compensation payments provided to farmers for losing animals affected by bTB contribute to the overall economic impact. Compensation amounts vary based on animal value, market prices, and regional considerations. The compensation paid to farmers for each reactor animal can range from £750 to £1,500 and does not include the lifetime value estimation of the animal.
  4. Trade Restrictions and Market Access: The presence of bTB can lead to trade restrictions imposed by other countries, affecting the UK’s ability to export livestock and animal products. These trade limitations result in reduced market access and potential loss of revenue for the agricultural industry. The economic impact of trade restrictions due to bTB is estimated to be tens of millions of pounds annually.

Bovine tuberculosis exerts a significant economic burden on the United Kingdom’s agricultural sector. The costs associated with testing, treatment, compensation, and trade restrictions have substantial implications for farmers, the industry, and the overall economy. It is essential to address and combat bTB effectively through comprehensive testing, control measures, and research into vaccination. By mitigating the economic impact of bTB, the UK can foster a more resilient and sustainable agricultural sector while safeguarding farmers’ livelihoods and ensuring food security for the nation.
