Pathogenic bacteria contamination of loin of Bali cattle slaughtered at modern and traditional abattoirs

Abstract

The aim of this study was to observe the contamination of pathogenic bacteria on the loin of the Bali cattle at abattoirs with modern cutting systems and traditional one. The loin samples were taken at modern abattoirs of Mambal which is managed by the Office of the Livestock Marine District of Badung. Loin sample that cutting traditional slaughter system was taken at Mambal village. The loins were taken into the laboratory of "Teknologi Hasil Ternak dan Mikrobiologi", Faculty of Animal Science Udayana University to test their pathogen bacteria content. The design used in this study was completely randomized design (CRD). Data obtained were analyzed with Two Independent Sample test (T-Test). The results showed that the total microbial content of TPC (Total Plate Count) on the loins cutting at modern abattoir were 1.2 x 10 5 and they were higher significantly different (P < 0.05) than the loins at the traditional abattoir 7.6 x 10 4. The content of coliform bacteria for 3.93 X10 3 indicate the results of the loin of the Bali cattle which was slaughtered in a modern abattoir, were significantly lower (P < 0.05) than at the traditional one (3.28 x 10 4). They were no contaminations with Escherichia coli on both loins of the Bali cattle modern or traditional abattoirs. From the data mentioned above, it can be concluded that the content of both TPC loin was still below the SNI threshold (SNI 7388, 2009). But pathogenic bacteria coliform content of the loin of the Bali cattle at traditional abattoirs was more polluted than the modern one. Even though both of them were still upper than the threshold of SNI (Standar Nasional Indonesia).
