| description | Bovine Tuberculosis (bTB) is a One Health issue that interconnects human health with animal and environmental health. Due to its importance, cattle (the main host) it is under a national eradication programme in Portugal. Within it, meat inspection is considered a cost-effective procedure in bTB surveillance. The Commission's Implementing Regulation (EU) 2019/627 changed the post-mortem meat inspection requirements applied to cattle, essentially reducing handling and incisions in young cattle (<8 months). To study the impact of these changes on the surveillance of bovine Tuberculosis, data (age, sex, fitness, breed, lesions, laboratory results and post-mortem decisions) on suspected and confirmed cases of bTB detected at routine slaughter of the period from October 2010 to January 2020 were analysed.From a total of 3,279,548 slaughtered animals, meat inspection detected 808 suspected cases. Of these, 381 cases were laboratory confirmed. The estimated global prevalence was 11.6 cases/100,000, increasing with age: 3.5, 5.9 and 27.3 cases/100,000 in, respectively, the groups <8 months, 8 to 19 months, and ≥ 20 months. The prevalence was higher in females (16.3 vs 7.3 cases/100,000 in males) and in beef cattle (16.3 vs 1.4 cases/100,000 in dairy cattle). Among the confirmed cases, mediastinal and bronchial lymph nodes were the most reported locations. Based on the results, there is no evidence of a negative impact on the application of Regulation (EU) 2019/627 on bTB surveillance in animals ≥8 months. For the <8 months group the change to a visual inspection protocol could lead to a failure in the detection of bTB cases. Considering the epidemiological situation, the incision of the mediastinal, bronchial and retropharyngeal lymph nodes in cattle <8 months should be maintained. |
