The European Union has declared Catalonia free of bovine tuberculosis, a disease that has been eradicated after a concerted effort from various stakeholders including farmers, administrators, companies, laboratories, and healthcare professionals. This status, effective from January 26, 2023, signifies a significant achievement in animal health. However, ongoing surveillance is necessary to maintain this status, with a focus on stricter disease monitoring in various animal species. The Support Service for Slaughterhouses of IRTA-CReSA, supported by ASPCAT, will play a key role in this surveillance.
