Survey on Bacteriological Contamination of Restaurants in Seoul Area

Abstract

This study was performed to investigate the sanitation of restaurants in Seoul Area. The subjects were 153 wet towels, 64 cold noodle soup and 190 barely tea. The results were as follows: In wet towels: The detected rate of standard plate counts was $86.9\%$ (133 samples) and average count was $1.8\times10^3/g$ $the detected rate of coliform was $37.9\%$ (58 samples) and average count by MPN method was $2.0\times10^3/100g$, the detected rate of fecal coliform was $15.7\%$ (24 samples) and average count by MPN method was $3.2\times10/100g$. In cold noodle soups: The detected rate of standard plate counts was $100\%$ (64 samples) and average count was $9.4\times10^5/ml$, the detected rate of coliform was $75\%$ (48 samples) and average count by MPN method was $6.0\times10^5/100ml$, the detected rate of fecal coliform was $51.6\%$ (33 samples) and average count by MPN method was $3.4\times10^3/100ml$. In barely tea: The detected rate of standard plate counts was $87.4\%$(166 samples) and average count was $5.8\times10^3/ml$the detected rate of coliform was $66.3\%$ (126 samples) and average count by MPN method was $3.9\times10^3/100ml$, the detected rate of fecal coliform was $32.6\%$ (62 samples) and average count was by MPN method was $4.7\times10/100ml$.
