Abstract

The purpose of this study was to apply the Hazard Analysis Critical Control Point (HACCP) system to the production of dressing. The hazard analysis examined the main materials, industrial water, microbial evaluation, and airborne microorganisms of each working area, as well as the pathogenic microbial contamination risk. The survey was conducted at SJ Company in Jincheon (Chungchengbuk-do), Korea for 30 days from April 1, 2012 to April 30, 2012. The results showed that raw material microorganisms had a total plate count in industrial water below $3.00{\times}10$ CFU/mL in working room I, working room II, the packing room, washing water, and the inspection room for five times in each place. During dressing production (including heat treatment and mixing), general bacteria were detected at an average of $3{\times}10$ CFU/mL, but yeast, mold, and pathogenic bacteria were not detected. Airborne microbiological evaluation (for total plate count, yeast, and mold) found levels below the legal limit at each working area. While workers were positive for microbes in total plate counts, coliform and Staphylococcus aureus were not detected. In conclusion, standards for hygienic management should be established to prevent and decrease hazards, such as general bacteria and pathogenic microorganisms (for example, E. coli, B. cereus, Listeria spp, Salmonella spp, Staph. aureus, Clostridium perfringens, yeast, and mold), and to found critical limits for microorganisms with an HACCP system.

Dressing 가공공정에 대한 HACCP(Hazard Analysis Critical Control Point) 시스템 구축을 위하여 위해요소 분석을 실시하였다. 위해요소 분석은 주원료, 용수, 미생물 평가, 작업장별 공중 낙하균과 종업원에 대한 병원성 미생물 검사를 하였다. 충청북도 진천 소재의 SJ 회사에서 2012년 4월 1일부터 30일까지 30일 동안 수행하였다. 그 결과 원료의 미생물은 5회 동안 검출되지 않았으며, 작업장 I과 작업장 II, 포장실, 세척용수, 검사실에서 사용된 용수의 총균수는 $3.0{\times}10^1$ CFU/mL 이하로 검출되었다. 드레싱 생산과정 중 열처리 및 혼합 과정에서 총균수는 평균 $3{\times}10$ CFU/mL가 검출되었으나 대장균과 진균류, 병원성 미생물은 검출되지 않았다. 공중 낙하균(총균수와 진균류)은 각각의 작업장에서 법적 허용치 이하로 검출되었다. 작업자들의 총균수 미생물 평가에서 모두 양성반응이었으나 대장균과 황색포도상구균은 검출되지 않았다. 결론적으로 위생관리 기준은 HACCP 시스템을 위한 미생물의 한계기준과 일반세균과 병원성 미생물과 같은 위해요소를 예방 및 감소시키기 위하여 설정하여야 한다.
