Abstract

This study, funded by Jeju Special Self-Governing Province, evaluated the bacterial contamination in disposable wet wipes used in restaurants, coffee shops, and bakery shops. The materials used are 55 disposable wet wipes collected from general restaurants. The number of average bacteria found was $4.21{\times}10^3CFU/mL$ in 50 disposable wet wipes; in the other five disposable wet wipes, no bacterial contamination was found. The highest number of bacteria was measured as $16.67{\times}10^3CFU/mL$. Total bacterial count of separated are 71 strains. Among the 71 identified strains, 15 were Staphylococcus aureus and 3 were Pseudomonas aeruginosa. This can be an important problem. This study measured the level of bacterial contamination and identified the strains isolated in wet wipes. This study may be important as it provides the basis for establishing sanitation standars for wet wipes.

2016년 4월부터 6월까지 제주특별자치도에 위치한 대중음식점, 커피전문점 및 제과 제빵점 등에서 제공하는 일회용 물티슈를 대상으로 미생물의 오염도를 평가하였다. 사용된 재료는 일회용 물티슈 55종을 사용하였다. 대중음식점 일회용 물티슈 55종의 평균 세균 수는 $4.14{\times}10^3CFU/mL$이었으며, 세균이 자라지 않은 물티슈는 5종이었다. 가장 높게 측정된 세균 수는 2종의 물티슈에서 $16.67{\times}10^3CFU/mL$ 이상으로 나타났다. 순수 분리한 총 균수는 71균주이며, 이 중 황색포도알균(Staphylococcus aureus) 15균주, 녹농균(Pseudomonas aeruginosa) 3균주를 동정하였다. 이는 대중음식점에서 공급하는 물티슈의 세균 오염도가 심각하다는 것을 반영하며 기회감염의 원인이 되는 Staphylococcus aureus와, Pseudomonas aeruginosa가 발견된 것은 주목할 만하다고 볼 수 있다. 본 연구를 통해 한 번 사용 후 버리는 일회용품이며, 수개월 내지는 1~2년 보관하면서 사용하는 제품인 일회용 물티슈의 위생관련 기준 마련에 기초자료를 제공하고 대중음식점 등에 대한 위생관리 감독 강화와 개선방안 및 개인 위생관리 및 국민보건 수준향상에 기여 하고자 한다
