Abstract

An investigation was conducted for the hygienic quality of fresh, chilled and frozen beef sold in open markets and supermarkets in the Kuala Lumpur and Petaling Jaya areas. The meat samples were analysed for the presence of microorganisms. The results showed that there were a considerable high counts of bacteria in all the three kinds of meat samples, although there were no visual sliminess and off-odour changes. The range of counts fell between 10² and 10⁶ cells per gram. Fresh beef from the open markets has the highest average number of Total Bacterial Count (27.33 x 10⁶/g), Total Coliform Count (2 1.90 x 10⁶/g), and Staphylococcus Count (4 .33 x 10²/g). The supermarket beef showed that chilled beef had the highest average Total Bacterial Count (8.86 x 10⁶/g), Total Coliform Count (1.99 x 10⁶/g), Psychrophillic Count (8.87 x10⁴/g), and Staphylococcus Count (1.14 x 10²/g), compared to the frozen beef : 1.30 x 10⁶ /g, 0.5o x 10⁶ /g, 6 .03 x 10⁴ /g, 0.44 x 10² /g respectively. Thus, in general, hygienic practice was not strictly observed by the retailers, either from the open markets or supermarkets which resulted in the high counts. Nevertheless, no Salmonella species and coagulase-positive Staphylococcus aureus were detected from all the meat samples.
