Summary: | The purpose of this study was to analyze the personal hygiene status of foodservice employees as well as microbiological counts of their hands according to food safety education. A survey was conducted for employees who worked at five foodservice facilities, and the results of the survey were assessed using the SAS program (ver. 9.3). A total of 20 employees' hands were sampled to analyze aerobic plate counts (APCs), coliforms counts (CCs), and Staphylococcus aureus. The food safety education program was composed of four education sessions, including microbiological evaluation of employees' hands. According to the survey results, all employees wore a sanitary uniform, hair cap, and shoes. However, 96% of employees used the restroom wearing sanitary shoes, whereas just 20% of them washed their hands using the standard method. Additionally, employees washed hands after using the restroom (100%), before using single-use gloves (76%), after eating (76%). The results of the microbiological hazards analysis of foodservice employees' hands showed that the average numbers of APCs and CCs before cooking were 5.53 log CFU/hand and 2.95 log CFU/hand respectively, whereas the average numbers of APCs and CCs while cooking at foodservice facilities were 6.49 log CFU/hand and 3.29 log CFU/hand, respectively. Staphylococcus aureus was detected in 10% of their hands before cooking and 5% of their hands while cooking. The average numbers of APCs and CCs were significantly reduced before cooking as well as while cooking, and Staphylococcus aureus was not detected in any of the samples as the frequency of food safety education increased. In conclusion, this study shows that it is necessary for foodservice employees to regularly participate in food safety education with effective instruments in order to improve their hygiene level. 사업체 급식소 조리종사원을 대상으로 위생교육을 한 후 교육 효과를 평가하고자 위생 교육 전후에 조리종사원 손의 미생물 수준을 검사한 결과는 다음과 같다. 조리종사원의 개인위생관리 실태 조사 결과 위생복 위생모 위생화는 전원 착용하였으나 위생화를 착용한 채 화장실을 가는 경우가 전체의 96%였다. 또한 조리종사원 손 씻기 방법은 비누 세척${\rightarrow}$헹굼${\rightarrow}$건조${\rightarrow}$소독을 하는 경우가 20%였고, 온수 사용은 32%, 일회용 종이수건으로 건조하는 경우는 36%였다. 손을 씻는 경우는 용변을 본 후(100%), 식사 후(76%), 일회용 장갑 착용 전(76%) 등이 많았고, 작업이 바뀔 때(24%)가 가장 낮았다. 그리고 조리작업 전 조리종사원 손의 미생물학적 위해분석 결과 일반세균수는 평균 5.53 log CFU/hand, 대장균군수는 평균 2.95 log CFU/hand, 황색포도상구균의 검출률은 10%였고, 조리작업 중의 조리종사원 손의 위해 분석 결과는 일반세균수가 평균 6.49 log CFU/hand, 대장균군수가 평균 3.92 log CFU/hand, 황색포도상구균의 검출률은 5%였다. 총 4회의 위생교육 후와 추후관리를 위한 미생물 검사 결과에서 위생교육 전에 비해 조리종사원 손의 미생물 검출량은 조리작업 전 일반세균수(P<0.01)와 대장균군수(P<0.001), 조리작업 중 일반세균수(P<0.001)와 대장균군수(P<0.001)가 모두 유의적으로 감소하였고, 황색포도상구균은 1회차 위생교육 시행 후부터 추후관리 검사 결과까지 조리작업 전과 조리작업 중에 조리종사원의 손에서 전혀 검출되지 않았다. 위의 결과를 종합해볼 때 조리종사원의 손 위생 수준은 다양한 교육매체와 도구를 활용하여 체계적으로 위생교육을 했을 때 효과적으로 개선할 수 있다고 판단된다. |
