| Abattoirs considered as sources of valuable information on the incidence of animal diseases and conditions, some of which may be zoonotic. As bovine tuberculosis which still one of the major health problem. A total of 360 meat samples, lymph nodes (prescapular L.N.and Prefemoral L.N. and Axilary L.N.) and internal organs (Livers, Kidney and Spleen) collected from carcasses after slaughtering of tuberculin positive animals were examined bacteriologically and the results of conventional culture techniques showed that 136 out of 180 examined samples were positive for isolation of mycobacteria (75.5%). and the rate of isolation at different abattoirs ranged from 73.3 % to 85 %. Concerning the collected samples out the target abattoir, 26 out of 180 examined samples were contaminated with mycobacterium Spp. (14.4. %). The results of real time PCR technique revealed that, all of tested tissue samples of 180 tuberculin positive animals were positive with percentage (100%). These results proved the accuracy of the judgment policy of the Egyptian organization which able to eliminate all the positive cases of bovine tuberculosis in some examined governorates. While the detection of contaminated meat with mycobacterium Spp. Proved the hygienic approach for slaughtering out the governmental abattoirs and the bad intended or non - intended selection of slaughtered animals from diseased one. | ||||
