Abstract

The purpose of this study was to analyze the microbiological hazards of prepared foods, raw materials, utensils and workers' hands and to evaluate cross-contamination of bacteria in foodservice establishments. Aerobic plate counts, coliforms, E. coli, E. coli O157:H7, Salmonella spp., Staphylococcus aureus and Listeria monocytogenes were tested. According to the microbiological evaluation, there were many cases of contamination of bacteria. Staphylococcus aureus was detected in chicken stew (Korean type), Japchae, Bibimbap and Kongnamul-muchim at the A foodservice establishment and Jwieochae-jorim at the B foodservice establishment. E. coli was detected in Ojingeochae-muchim at the C foodservice establishment. E. coli O157:H7, Salmonella spp. and Listeria monocytogenes were not detected in any of the tested samples. Critically, microbiological contamination of raw materials, utensils and workers' hands could result in contamination of prepared foods, thus, attention needs to be given to sanitation of raw materials, workers' hands and utensils to reduce or eliminate contamination of bacteria.

급식규모와 운영형태가 유사한 3곳의 급식소를 대상으로 원재료, 조리기구 및 조리종사원 손과 최종조리음식간의 미생물 오염실태를 분석한 결과는 다음과 같다. A 급식소에서는 닭볶음탕, 잡채, 비빔밥, 콩나물무침에서 황색포도상구균이 검출되었다. 닭볶음탕은 조리종사원의 손, 재료를 손질한 도마, 양파에서 황색포도상구균이 검출되었으므로 조리종사원의 손이나 도마를 통한 교차오염이 발생한 것으로 판단된다. 잡채는 조리종사원의 손, 당면을 삶아 건진 바구니, 양파와 양파를 손질한 도마에서 모두 황색포도상구균이 검출되었으므로 이들 간의 교차오염이 발생했을 것으로 생각된다. 비빔밥과 콩나물무침은 해당일 조리를 담당한 종사원의 손에서 황색포도상구균이 검출되었으므로 조리종사원 손에 의한 오염이 발생한 것으로 판단된다. B 급식소의 쥐어채조림은 원재료의 황색포도상구균이 조리과정에서 그대로 전이되어 조림 후에도 검출되었다. C급식소의 오징어채무침에서는 대장균이 검출되었다. 오징어채무침은 가열조리공정을 거치지 않는 메뉴로서 원재료인 오징어채에서 검출되었던 대장균이 그대로 최종조리 후까지 전이된 것으로 판단된다. 급식소 최종음식의 안전성 확보를 위해서는 위생적인 원재료의 구매와 사용, 조리종사원 개인위생의 개선, 조리기기의 철저한 세척 및 소독관리가 선행되어야 할 것으로 사료된다.
