BACTERIOLOGICAL STUDIES ON MARKET SEA FOODS 2. Sanitary Indicative Bacteria in Slices of Raw Fish

시판 수산식품에 대한 세균학적 연구 2. 생선회의 위생지표 세균에 관하여

This examination was carried out to evaluate the sanitary quality of slices of raw fish being served in the restaurants. Twenty five kinds of slices of raw fish collected from various restaurants in Busan Korea were examined during the period from March to May in 1971. As the evaluation factors of sanitary quality, the contents of sanitary indicative bacteria such as coliform group, fecal coliform, feral streptococci and enterococci and plate counts were determined. The results obtained are as in below: 1. The numbers of fecal streptococci and enterococci MPN were much greater than those of coliform group and fecal coliform. 2. The median value of coliform group MPN was 3,300 per 100 grams of the sample examined and those of enterococci was 5,400. The median value of plate counts was $1.8\times10^5$ per gram. 3. Fifty-two percent of the samples examined were exceeded fecal coliform MPN 930 per 100 grams. 4. As a sanitary indicative bacteria fecal coliform MPN was more reasonable than enterococci 5. The grade of restaurants was not correlated with the bacterial quality of the foods served. 6. No correlation between the numbers of sanitary indicative bacteria ana plate counts was observed.

우리가 즐겨 먹고 있는 생선회의 위생지표 세균의 오염도를 파악하고 나아가서 식품의 위생관리에 필요한 기초자료를 얻고자 1971년 3월부터 5월까지 부산시내 각종 음식점에서 손님에게 제공된 상태의 생선회 25종류를 수집하여 위생지표 세균인 대장균군, 분변계대장균, 분변계연쇄상구균, 장구균 및 일반생균수를 시험하여 다음과 같은 결과를 얻었다. 1. fecal streptococci나 enterococci MPN은 coliform group이나 fecal coliform MPN보다 매우 높았다. 2. 대장균군과 장구균의 중앙치는 각각 3,300, 5,400 이었으며 일반생균수의 중앙치는 $1.8\times10^5$이었다. 3, 분변계대장균 MPN 230이상인 것이 시료의 $52\%$였다. 4. 생선회의 위생지표 세균으로서는 장구균보다 분변계대장균이 보다 합리적이었다. 5. 일반적으로 생각하는 음식점의 우열과 세균 오염도는 일치하지 않았다. 6. 각 위생지표 세균과 일반생균수 사이에는 일정한 상관관계는 없었다.
