Abstract

This study was investigated to determine the contamination levels of total aerobic bacteria, coliform group, $E.$ $coli$ and food-borne pathogens of side dishes from 2 traditional markets (100 samples) and 2 super markets (100 samples) located on Ulsan. The levels (range) of total aerobic bacteria was 4.75 log CFU/g (1.60~6.92 log CFU/g) in traditional market and 4.62 log CFU/g (2.00~6.46 log CFU/g) in super market, respectively. Coliform was detected in 64 and 66 samples sold at traditional markets and super markets, respectively. $E.$ $coli$ was detected in 4 and 6 samples sold at traditional markets and super markets, respectively. The food-borne pathogens, namely $Bacillus$ $cereus$ and $Listeria$ $monocytogenes$ were detected in 1 sample sold at traditional markets, respectively, and $Bacillus$ $cereus$ was detected in 4 samples sold at super markets. However, other pathogens such as $Salmonella$ spp., $Shigella$ spp., $Vibrio$ $parahaemolyticus$, $Yersinia$ $enterocolitica$, $Clostridium$ $perfringens$, $Camphylobacter$ $jejuni$ and Pathogenic $E.$ $coli$ were not detected. The $Saengchae$ and $Seasoned$ $Jeotgal$ were relatively vulnerable compared to the others in the food-borne pathogens.

본 연구에서는 울산지역의 재래시장 및 대형할인점에서 판매되는 즉석 반찬류의 미생물학적 안전성을 평가하여 이들 반찬류의 위생상의 문제점을 파악하고 이를 개선하기 위한 기초자료로 삼고자 재래시장(2곳), 대형할인점(2곳) 총 4곳에서 구입한 반찬류 4종 20품목 200건에 대해 위생지표세균인 일반세균, 대장균군, 대장균과 식중독 원인균인 $Salmonella$ spp., $Shigella$ spp., $Staphylococcus$ $aureus$, $Listeria$ $monocytogenes$, $Vibrio$ $parahaemolyticus$, $Yersinia$ $enterocolitica$, $Bacillus$ $cereus$, $Clostridium$ $perfringens$, $Camphylobacter$ $jejuni$, Pathogenic $E.$ $coli$를 조사하였다. 일반세균의 평균 검출량 (범위)는 재래시장이 4.75 log CFU/g (1.60~6.92 log CFU/g), 대형할인점이 4.62 log CFU/g(2.00~6.46 log CFU/g) 수준으로 구입 장소에 따른 유의적인 차이는 없었다. 대장균군의 검출건수(검출률)는 재래시장이 총 64건(64%) 으로, 젓갈류와 절임류가 각각 20건(80%), 조림류 13건(52%), 생채류 11건(44%)의 순을 나타내었다. 대형할인점은 66건(66%)이 검출되었고, 젓갈류와 조림류 19건(76%), 절임류 18건(72%), 생채류 10건(40%)의 순을 보여 재래시장과 마찬가지로 생채류가 낮은 검출을 나타내었다. 그리고 평균 검출량은 재래시장과 대형할인점 모두 생채류가 대체적으로 낮은 경향을 보였다. 대장균은 재래시장에서 오징어젓갈 (젓갈류) 1건, 된장콩잎 (절임류) 2건, 깻잎장아찌 (절임류) 1건 등 4건(4%)에서 검출되었고, 생채류와 조림류에서는 검출되지 않았다. 그리고 대형할인점은 생마늘쫑 (생채류) 1건, 고들빼기 (절임류) 1건, 된장콩잎 (절임류) 2건, 깻잎장아찌 (절임류) 2건 등 6건(6%)에서 검출되었고, 젓갈류와 조림류에서는 검출되지 않았다. 식중독균 검사결과, $B.$ $cereus$와 $L.$ $monocytogenes$는 재래시장에서 각각 1건(생채류 1건, 젓갈류 1건)이, $B.$ $cereus$는 대형할인점에서 4건(생채류 1건, 절임류 1건, 조림류 2건)이 확인되었으며 $Salmonella$ spp., $Shigella$ spp., $Vibrio$ $parahaemolyticus$, $Y.$ $enterocolitica$, Pathogenic $E.$ $coli$, $C.$ $jejuni$ 등 나머지 식중독균은 검출되지 않았다. 결론적으로 반찬류의 안전성은 위생지표세균 측면에서는 절임류, 젓갈류, 조림류가 (특히 절임류), 식중독균 측면에서는 생채류와 젓갈류가, 그리고 대형할인점이 재래시장에 비해 상대적으로 취약하여 이에 대한 위생관리가 필요하다고 판단된다. 따라서 시판 반찬류의 미생물적 안전성 확보를 위해 제조단계, 유통단계, 판매단계에 이르기까지 안전을 위한 총체적인 관리방안의 수립과 체계적인 관리가 요구된다.
