Abstract

The aim of this research was to inspect the microbiological quality of 30 samples of Tao–Kua, southern Thai salad style food which collected from 6 food vendors, FV, sold in Paphayom and Mueang District, Phatthalung Province. The results were compared with the microbiological criteria standard determined by Bureau of Quality and Safety of Food. The results were shown that all samples of FVA and FVC had aerobic plate count, APC, less than 1 x 106 CFU/g but all samples of FVB and FVE as well as 2 and 1 samples of FVD and FDF including FVD2, FVD3 and FVF3, respectively, had APC more than 1 x 106 CFU/g. The quantities of Bacillus cereus, Clostridium perfringens and Staphylococcus aureus were <10, <10 and <10 CFU/g, respectively in all samples of all food vendors. Most samples had MPN/g of Escherichia coli  3 except FVA3, FVF2 and FVF5. Listeria monocytogenes, Salmonella spp., Vibrio cholerae and V. parahaemolyticus were not found in all sample. From these results can be concluded that only 3 samples, 10% of all samples, including FVA3, FVF2 and FVF5 were in the criteria of the mentioned standard abov
