Abstract

This study was performed to investigate hygienic behavior of food workers on the awareness of hand-washing, and the microbial load of their hands. This study focused on the comparison of fast food restaurant workers and full-service restaurant workers. A questionnaire survey and microbiological analysis were carried out for thirty fast food restaurant workers and forty full-service restaurant workers. Samples for microbiological analysis were collected through the glove-juice method from the hands of the food workers, and were analyzed for the presence of aerobic plate counts, total coliforms, fecal coliforms, Escherichia coli, Staphylococcus aureus, and Salmonella spp. Microbiological analysis was done according to the Food Code of Korea. In the survey, significant differences (p < 0.05) were found between the fast food restaurant workers and full-service restaurant workers in the use of hand washing tools and method of turning off water. More full-service restaurant workers responded to wash their hands after touching face, hair, or clothes; after handling raw food materials, and more fast food restaurant workers periodically (p < 0.05). Aerobic plate counts were higher in fast food restaurant workers while total coliforms were higher in full-service restaurant workers (p < 0.05). No remarkable difference was found between the two groups in the load of fecal coliforms, E. coli, S. aureus, and Salmonella spp. Poor hand hygiene practices were indicated by the positive results for E. coli, S. aureus, and Salmonella spp. on the hands of some food workers in both groups. The findings of this study emphasize the need for strict adherence to hand hygiene compliance among the food workers.

본 연구는 패스트푸드점 종사자와 일반음식점 종사자의 손 위생관리를 조사하고 이들에 대한 비교를 하기 위하여 수행되었다. 패스트푸드점 종사자 30명과 일반음식점 종사자 40명을 대상으로 손 씻기 의식(손 씻기 방법, 손 씻기 이행 상황 등)을 조사하고 손에서 지표세균 및 식중독성 세균(일반세균, total coliforms, fecal coliforms, E. coli, S. aureus 및 Salmonella spp.) 오염도를 시험하였다. 손 씻기 의식은 설문조사에 의하여, 미생물시험을 위한 시료채취는 glove-juice법에 의하여, 그리고 미생물시험은 식품공전에 준하여 수행하였다. 설문조사에서 손 씻기 방법에 있어서는 손 씻기 도구 사용 및 손 씻기 후 물 잠금방법에서 두 집단 간에 유의한 차이가 있었다(p < 0.05). 손 씻기를 이행하는 상황에 대해서는 신체부위나 옷을 만졌을 때, 생식품 취급 후, 그리고 주기적 손 씻기 등에서 두 집단 간에 유의한 차이가 있었다(p < 0.05). 손의 미생물 시험에서 일반세균수 오염도는 패스트푸드점 종사자가 일반음식점 종사자보다 높았고, total coliforms 오염도는 패스트푸드점 종사자가 일반음식점 종사자보다 낮았으며(p < 0.05), 나머지 미생물은 두 집단 간에 유의한 차이를 보이지 않았다. 그렇지만 E. coli, S. aureus 및 Salmonella spp. 양성자 비율은 패스트푸드점 종사자가 일반음식점 종사자에 비하여 낮은 편이었다. 설문조사에서 일부 항목에서 차이를 보였지만 전반적으로 현저한 차이를 보이지 않은 결과와 더불어 두 집단 모두 E. coli, S. aureus 및 Salmonella spp. 양성자가 나타나 있어 손 위생관리가 철저하게 이루어지지 않았음을 알 수 있다. 두 집단 모두 손 위생관리 수준이 향상되어야 할 것이며, 이를 위한 교육 및 훈련 프로그램이 필요한 것으로 본다.
