Abstract
The study aimed to assess the microbial contamination (Coliform, Escherichia coli, Salmonella) in pork that was sold at four markets (An Cuu, Ben Ngu, Dong Ba, and Tay Loc) in Hue city. A total of 60 pork samples were collected to analyze the contamination level of coliform, Escherichia coli (E. coli), and Salmonella according to QCVN 01-04:2009/BNNPTNT. coliform and E. coli were identified by spreading on Petrifilm plates, and Salmonella was identified by spreading on XLD media. The results showed that 100% of pork samples were contaminated with coliform; 88.30% of samples were contaminated with E. coli and 50.0% of samples were contaminated with Salmonella. The average amount of coliform in the samples was 5.87×104 CFU/g, which is higher than the allowable standard (TCVN 7046:2009). The number of E. coli is 0.72×104 CFU/g, which is also higher than the standard level. According to TCVN 7046:2009 standards, all samples collected from four markets did not meet the requirements of safe meat standards if 3 microbiological criteria were considered. The level of microbial contamination in pork samples in markets was not similar. Although the samples collected in Ben Ngu market had the lowest positive rate of E. coli (80.00%), its positive rate for Salmonella (60,00%) was the highest. Therefore, ensuring food safety is essential to limit the level of microbial contamination in retail pork in Hue city.
