본 연구의 목적은 대구 경북지역 초등학교에 공급되는 전처리 채소와 가공식품의 유통단계를 분석하고, 유통과정에서의 미생물 변화와 학교급식에 이용되는 식재료의 미생물 품질을 평가하기 위하여 실시되었다. 유통 중 박피도라지에서 일반세균 CFU/g, 대장균군 CFU/g, E. coli < , S. aureus < CFU/g, B. cereus < CFU/g이 검출되었다. 전처리 양파에서는 일반세균 CFU/g, 대장균군 CFU/g이 검출되

We evaluated changes in the microbiological quality and safety of food items (vegetables, seaweed, and processed food) supplied to elementary school food services to evaluate the distribution/delivery system. Pretreated vegetables, seaweed, and processed food were delivered to schools in refrigerated () vans that made several delivery stops before arriving at the schools. During the distribution stage, total plate and coliforms counts were: bellflower roots and CFU/g; blanched bracken , CFU/g; onion , CFU/g; soybean sprouts and CFU/g; soybean curd < and < CFU/g; and starch jelly < and < CFU/g, Escherichia coli CFU/g, and Staphylococcus aureus CFU/g were detected on peeled bellflower, whereas B. cereus < CFU/g, Listeria monocytogenes CFU/g, and S. aureus CFU/g, were detected on soybean sprouts. Most food items were double-wrapped in vinyl and placed in corrugated cardboard boxes prior to delivery, but the boxes, when placed in vans, were not segregated from other food items being delivered to schools and other destinations.
