Abstract

Products of animal origin, namely meat, eggs, and milk, must have good value and quality for human benefit and must be monitored regularly. The present study aimed to review the epidemiological mapping of the level of microbial contamination based on surveillance data in the Provinces of Bali and Nusa Tenggara. During 2017, a total of 1875 samples were collected from targeted places that did not have a veterinary control number (VCN) such as slaughterhouses, traditional markets, retail shops and meat supply companies (importers), then brought to the Disease Investigation Center (DIC) Denpasar for analysis. Microbial contamination was tested using the total plate count (TPC) method, according to laboratory procedures for DIC Denpasar. The test results showed that 56.9% of the samples contained germs that exceeded the maximum microbial contamination limit (MMCL) stipulated in SNI 7388: 2009, namely 1×106 colonies/g. The contaminant germs were dominated by E. coli (73.8%). There was a highly significant (P<0.001) difference in the number of E. coli that exceeded the maximum limit microbial contamination (MLMC) values detected between the three provinces, the four types of samples tested, and the type of slaughterhouses/markets. However, all samples tested did not contain pathogenic bacteria such as Staphylococcus aureus, Salmonella spp., and Campylobacter spp. This data suggested that the hygiene level of animal products in the region was low which can threaten the health of consumers.
