Abstract

According to food poisoning statistic data of 2000, the food poisoning outbreaks have occurred mainly by meat (27.9%), shellfish and its processed products (26.0%), and ready-to eat meals (24.0%) such as Kimbap and packed lunch boxes. The major causative flood poisoning bacteria were Salmonella spp. (35.6%), Staphylococcus aureus(11.3%) and Vibrio parahaemolyticus (3.2%). In this study, we conducted the isolation and enumeration for S. aureus in Kimbap. This monitoring data will be applied to the following study, risk assessment. The Kimbap samples were collected from department stores, convenient stores and snack bars located in Seoul, Busan, Daejeon, and Gwangju. The overall isolation rate of S. aureus from 214 Kimbap samples was 34.1% and the average count was 623 cells. Enterotoxin typing test for isolates showed 42.5%, 4.1% and 2.7% for type, A, B and C, respectively. There was no significant seasonal difference in S. aureus isolation, but the average count in summer(793 cfu/g) was 1.8 times higher than that of winter(446 cfu/g).

2000년 국내 식중독발생 통계에 따르면, 원인식품별 식중독발생건수는 육류 등이 27.9%, 어패류 및 가공품이 26.0%, 복합조리식품(김밥, 도시락)이 24.0%의 비율을 차지하고 있으며, 원인균별 식중독발생건수는 Salmonella spp.가 28.8%로 1위, Vibrio parahaemolyticus가 13.5%로 2위, Staphylococcs aureus가 8.7%로 3위를 차지하고 있다. 이에 본 연구에서는 김밥 중 황색포도상구균에 대한 분포도조사 및 오염정도를 분석하여 위해도평가의 기초자료로 활용하고자 하였다. 서울, 부산, 대전, 광주의 백화점, 편의점, 분식점 등에서 구입한 김밥 총 214건에 대한 황색포도상구균의 정량 및 정성실험 결과, 균검출율은 34.1%였고, 평균균량은 623 cfu/g 이었다. 분리균에 대한 enterotoxin 실험결과 A type 42.5%(31주/73주), B type 4.1%(3주/73주), D type 2.7%(2주/73주)의 분포를 보였다. 또한 유통·판매형태별로는 분식점의 검출율이 42.8%로 백화점(25.8%)및 편의점(12.3%)보다 높게 나타났으며, 계절별 평균균검출율은 비슷하였으나, 정량검사결과 여름철(793 cfu/g)에 겨울철(446 cfu/g)보다 균량이 1.8배 높게 나타났다.
