초록

본 연구는 대도시지역(서울, 대전, 부산, 광주)에서 판매되는 길거리 식품(김밥, 어묵, 순대)에 대한 미생물 모니터링 검사를 실시하여, 이들 제품에 대한 위생 안전성 확보를 위한 기초 자료를 제공하기 위해 진행되었다. 김밥의 총호기성균은 5.1~9.9 log CFU/g으로 검출되었으며, 여름철에 가장 높게 검출되었다. 호냉성균은 총호기성균과 유사한 패턴으로 검출되었으며, 여름철에 수거된 순대 7건에서 6.0~7.9 log CFU/g 수준으로 검출되었다. Total coliform은 53.6%의 검출률을 나타내었으며, 김밥의 70.8%에서 4.0 log CFU/g 이상 검출되었다. E. coli는 김밥과 순대에서 15건이 검출되었으며, 어묵에서는 검출되지 않았다. 식중독균중 S. aureus가 28건(7.8%)이 검출되었으며, C. perfringens는 12건(3.3%)이 검출되었다. 특히 김밥에서 S. aureus, C. perfringens가 각각 24건, 10건에서 검출되어 식중독 발생 가능성이 높은 것으로 판단되었다. 그리고 계절별로 보면 겨울에 비해 봄, 여름의 검출률이 높았으며, 지역별로 보면 부산지역에서 가장 높은 검출률을 보였다.

This study examined microbiological contamination of street foods(kimbab, fish cake, Korean sausage) by microbiological analysis. A collection of 360 samples of street foods was obtained seasonally in four major cities(Seoul, Daejeon, Busan, Gwangju) in Korea. Aerobic mesophilic counts ranged between 1.0 and 9.9 log CFU/g, with the highest count recorded from Kimbab. Counts of psychrotrophic microorganisms were as high as those of mesophilic microorganisms. Total coliform populations between <1.0 and 7.5 log CFU/g were found in 53.6% of samples. Escherichia coli 4.4%, Staphylococcus aureus 7.8% and Clostridium perfringens 3.3%. Salmonella spp. and Listeria monocytogenes were not detected in any of the samples. Kimbab purchased in spring and summer showed higher S. aureus and Cl. perfringens contamination rates. Microbial contamination levels determined in the present study may be used as the primary data to execute microbial risk assessment of street foods.
