Abstract

The purpose of this study was to evaluate the application of ATP bioluminescence assay for effect assessment of hygiene visiting education on children's foodservice facilities in the local small town. The sanitary inspection results of the hygiene visiting education showed significant improvement in all items except 'To regularly disinfect cooking facilities, storage rooms, etc.' ATP bioluminescence analysis was performed on cooking utensils to evaluate the educational effect, and the results showed a correlation with the effect in most items. In the case of knives and cutting boards, all facilities showed a value of 20 RLU/cm2 or less after the educational support, and in particular, it was approximately 10 RLU/cm2 or less in national/public, corporation and private facilities. Correlation analysis between the post-education sanitary inspection results and ATP values for three items related to knives and cutting boards showed that they have a negative and high correlations.

본 연구는 경상북도 예천군에 소재하는 100인 이하의 어린이급식소 32개소를 대상으로 급식 위생·안전 순회지도 및 위생교육 지원에 따른 교육효과를 조사·분석함으로써 어린이급식소의 문제점을 파악하고, 올바른 개선방안을 제시하고자 하였으며, 위생·안전 체크리스트 분석 결과와 ATP 측정 결과의 상관관계를 비교·분석함으로써 위생교육의 효과를 평가하기 위한 ATP bioluminescence assay의 적용성을 검토하였다. 조사결과 설립 유형은 법인 9.4%, 국공립 18.7%, 기타 18.7%, 가정 21.9%, 민간 31.3% 순으로 확인되었고, 규모별로 집단급식소 25.0%, 소규모 급식소 34.4%, 비집단급식소 40.6% 순으로 조사되었다. 위생순회지도의 결과들은 '조리실, 식품 등의 원료·제품 보관실 등을 정기적으로 소독하는지 여부' 항목을 제외한 모든 항목에서 유의적인 개선을 보였으며, 위생순회지원에 따른 교육효과의 평가를 위해 칼, 도마, 고무장갑, 냉장고 손잡이, 정수기 꼭지 등 5가지 항목에 대한 ATP bioluminescence analysis가 수행되었다. 칼과 도마의 경우 전 개소 모두 순회 지원 후 20 RLU/cm2 이하의 수치를 보였으며, 특히 국공립시설, 법인시설, 민간시설에서 칼과 도마 모두 10 RLU/cm2 이하의 수치를 보였다. 조리기구 중 식품위생의 주요 기준이 되고 있는 칼과 도마를 중심으로 이와 관련된 항목인 '자외선 또는 전기 살균 소독기 설치 여부', '주방용구의 살균·소독제 또는 열탕의 방법으로 소독한 것을 사용하는지 여부', '어류·육류·채소류를 취급하는 칼·도마 구분 사용 여부' 항목들이 상관관계 분석을 통해 검증되었으며, 칼과 도마 모두에서 음(-)의 상관관계를 가지며 높은 상관성을 나타내었다. 이러한 결과는 위생교육의 효과에 대한 간편하면서도 객관적인 평가수단으로서 ATP bioluminescence assay의 가능성을 제시하는 것으로 사료된다. 전반적으로 제한적인 점검횟수로 인해 전 항목 모두 뚜렷한 개선을 확인할 수는 없었으나, 지속적인 교육지원을 통한 개선의 효과를 기대할 수 있을 것으로 판단된다.
