“…During 1998-2012 the prevalence of mycobacterium-like lesions in slaughter pigs fluctuated between < 0.1 and 0.85% (Tirkkonen 2017) and Finland is officially free of Mycobacterium bovis (Commission Decision 2003/467/ EC). Recently, Mycobacterium caprae has emerged in various European countries (Cvetnic et al 2006;Rodríguez et al 2011;Amato et al 2017) and should also be considered. As passive surveillance, Evira recommended that in cases of pronounced or generalized mycobacterium-like lesions, samples should be sent for further identification of the causative agent (Evira 2015).…”

The post-mortem inspection of domestic pigs within the European Union was revised in 2014, primarily to include visual meat inspection of each carcase and offal. Palpations and incisions were removed from routine meat inspection procedures, as they are mostly used to detect pathological lesions caused by organisms irrelevant for public health, and instead can cause cross-contamination of carcases with foodborne pathogens. However, examination of all external surfaces of the carcase and organs, declaration of patho-physiological lesions as unfit for human consumption, and possibility for minimal handling of carcases and offals were held in place. In addition, the European Food Safety Authority suggested that palpation and incisions should be performed outside the slaughter line, but this was not incorporated in the revised legislation. We surveyed in 2014 the opinions of meat inspectors and veterinarians using an online questionnaire to determine what practical measures are required for the visual meat inspection procedure and when meat inspection staff consider additional palpations and incisions necessary. Based on the survey, turning the carcase and organs or technical arrangements such as mirrors were seen necessary to view all external surfaces. In addition, the pluck set cannot be trimmed on the side line. Local lesions, such as abscesses and lesions in the lymph nodes, signs of systemic infection and lymphoma, were the major lesions requiring additional post-mortem meat inspection procedures. Meat inspection personnel raised concerns on the poor quality of food chain information and export requirements demanding palpations and incisions. The efficient use of visual meat inspection requires legislation to better support the implementation and application of it, changes in the slaughter line layout and a possibility to classify incoming pig batches based on their risk.

“…Although it is chiefly caused by Mycobacterium bovis, other members of the M. tuberculosis complex (MTBC) including M. tuberculosis, M. africanum (Cadmus et al, 2010), M. caprae (Cvetnic et al, 2007), M. orygis (Dawson et al, 2012) and M. microti (Michelet et al, 2020) are known to cause bTB in cattle. Other species-like human, goats, pigs, buffalo, dogs, primates, badgers, deer, possums and bison are also susceptible to M. bovis (Refaya et al, 2020).…”

Bovine tuberculosis (bTB) is one of the major zoonotic concerns of the world, as milk and meat from cattle are major products for human consumption. Bovine tuberculosis not only affects the health of cattle and poses an imminent zoonotic threat, but also causes significant economic loss in both developed and developing countries. This systematic review reports the prevalence of Mycobacterium tuberculosis complex (MTBC) organisms in slaughtered cattle showing tuberculosis‐like lesion (TBL) with available literature worldwide. Appropriate keywords were used to search various databases to collect articles pertaining to slaughterhouse studies. Bovine TB prevalence, based on the prevalence of MTBC organisms in slaughtered cattle showing TBL by culture, microscopy, PCR and spoligotyping, was assessed in each study using a random‐effects model and standardized mean with 95% confidence interval (CI). Heterogeneity was assessed by the I2 statistic. Publication bias was evaluated using funnel plots. Out of 72 hits, 37 studies were selected based on title and abstract. Ten articles were excluded due to lack of desired data, and 27 studies were included in the final analysis. From the selected articles, it was found that 426 [95% CI: 302–560] per 1,000 slaughtered cattle with TBL were positive for the presence of MTBC organisms. The sensitivity analysis showed that no individual study alone influenced the estimation of pooled prevalence. The prevalence of MTBC organisms in slaughtered cattle showing TBL by culture, microscopy, PCR and spoligotyping was 474[95% CI: 342–610], 385 [95% CI: 269–515], 218 [95% CI: 132–338], 326 [95% CI: 229–442], respectively, per 1,000 slaughtered cattle. Most of the slaughtered cattle were from the same locality as the slaughterhouse. The results obtained in this study suggest that abattoir monitoring can give an estimate of the prevalence of bTB in that locality. This study also emphasizes the need to test cattle and animal handlers who were in contact with bTB‐positive cattle.

“…The source of infection for swine may be sawdust, wood shavings, peat, soil, kaolin, water or feces of infected poultry, wild birds and swine or uncooked garbage (Pavlik et al, 2005 andCvetnic et al, 2006). Tubercle lesions are mainly observed in lymph nodes associated with gastrointestinal tract but in generalized tuberculosis, lesions are found in lungs, liver, kidneys, spleen and many other organs of the abdominal and thoracic cavities except skeletal muscles (Cosivi et al, 1998;Pavlik et al, 2005 andPalanivel et al, 2011).…”

Background: Swine tuberculosis (TB) is a highly progressive granulomatous infectious disease. The cases usually go undiagnosed and become a potent source of infection to other animals and humans. In Ayodhya and Sultanpur districts, no such study has been conducted so far. Keeping in view the zoonotic importance of this disease, the present study was, therefore, designed to study the prevalence of generalized swine tuberculosis in middle gangetic plain zone of Eastern Uttar Pradesh. Methods: Forty-two (42) pigs were presented for postmortem at Department of Veterinary Pathology, C.V. Sc. and A.H., ANDUAT, Ayodhya from nearby villages of Ayodhya and Sultanpur districts from April 2017 to February 2020. Pigs were screened for typical lesions of tubercles throughout the body during postmortem examination.Result: The prevalence was 7.14% out of 42 pigs presented for postmortem examination. Eight pigs (19.04%) had nodules in either lungs or liver but these were diagnosed negative for TB on ZN (Ziehl-Neelsen) staining. Typical tubercles were evident in liver, spleen and lungs and were characterized by the presence of circumscribed yellowish white raised lesions of various sizes and numbers. Microscopically, granulomatous lesions revealed necrotic areas surrounded by mixed inflammatory cells including macrophages, lymphocytes and plasma cells. The ZN stain reveals presence of acid fast bacilli in impression smear made from lung, spleen and liver.
