최근 친환경 농산물에 대한 소비자의 관심이 높아짐에 따라서 이들 친환경 농산물의 안전성에 대한 검증 요구가 증대되고 있다. 본 연구는 26종의 엽채류 및 4종의 과채류를 대상으로,재배유형(재래농법 및 유기농법)및 유통 경로 (대형마트 및 유기농전문점)에 따른 세균 및 기생충의 오염을 선택 감별배지, 자동 세균 동정 시스템, 현미경 관찰로 조사하였다. 수세하지 않은 농산물에 부착한 세균 집락 수는 농산물 균질액 1 mL(농산물 0.1 g) 당 범
As the consumption of environmentally friendly agricultural products increases, food safety is at the forefront of public health concerns. We analyzed the biological hazards of 26 species of leaf vegetables and 4 species of fruit according to types of cultivation (conventional or organic filming) and distribution system (giant retailers or organic food stores) using various culture media, automatic bacterial identification systems, and microscopy, Total bacterial count of unwashed agricultural product ranged from (from 0.1 g of agricultural products), and the average count dropped 25-fold (range, 8-60-fold) after water washing. Microbial levels of washed organic agricultural products were , and were not significantly different f개m the microbial loads on conventionally farmed produce. There was no significant difference in bacterial count from agricultural produce purchased from giant retailers or organic food stores. Total microbial count of Chinese cabbage, welsh onion, red chicory and kale were comparatively high, and Enterobacter cloacae was isolated most frequently. Parasites were detected in agricultural products purchased from conventional farm products in the stores of giant retailers, and in organic food stores, and parasite prevalence was especially high in Chinese cabbages and welsh onion. The study indicated that cultivation methods and distribution systems did not cause significant differences in biological contamination levels of agricultural produce. Some vegetables and fruits were highly contaminated effective sanitizing methods to reduce these biological hazards are needed.
