Abstract

Spread of pathogenic micro-organisms through contaminated hands is a well recognized way of transmitting disease such as food poisoning. We investigated the prevalence of aerobic plate counts, coliform bacteria, and food-poisoning bacteria on hands in various age groups. The average number of aerobic plate counts was 3.3 log CFU/hand in kindergarteners, 3.4 log CFU/hand in elementary students, 3.2 log CFU/hand in middle school students, 3.4 log CFU/hand in high school students, and 3.3 log CFU/hand in adults. Two kindergarteners, 6 elementary students, and 2 adults were positive for the coliform bacteria. Among the food poisoning bacteria we tested, S. aureus was isolated from 47 individuals. Eight isolates of B cereus were all from kindergarteners. C. perfringens was isolated from 7 individuals. Among 47 isolates of S. aureus, 25 isolates produced toxins. Seven of eight isolates of B. cereus produced toxins. None of seven C. peifringens isolates produced toxins. All 47 isolates of S. aureus were sensitive to ciprofloxacin, trimethoprim/sulfamethoxazole, clindamyccin, imipenem, rifampin and vancomycin. Four isolates (8.5%) were resistant to cefepime, chloramphenicol, cefotetan, and gentamycin. Five isolates (10.6%) were resistant to oxacillin and 6 isolates were resistant to tetracycline. This study shows that it is needs to be established policy of school lunch and personal sanitation management.

시민 건강을 위협하는 질병 및 식중독 오염의 감염 매개체가 되는 손에 대한 위생실태를 점검하고자 유아원, 초등, 중등, 고등학생 및 일반인 등을 대상으로 오염의 지표인 일반세균 및 대장균군과 식중독 원인균인 세균성이질, 살모넬라, 황색포도상구균, 장병원성대장균, V. parahemolyticus, Y. enterocolitica, B. cereus, C. perfringens, L. monocytogenes, C. jejuni에 대해 조사하여 다음과 같은 결과를 얻었다. 1. 일반세균과 대장균군 등의 위생세균에서 대장균군은 유치원생 2명, 초등학생 6명, 성인에서 2명이 검출되었으며, 일반세균은 유치원생의 경우 평균 3.3 log CFU/hand, 초등학생은 3.4 log CFU/hand, 중학생은 3.2 log CFU/hand, 고등학생은 3.4 log CFU/hand, 성인은 3.3 log CFU/hand로 나타났다. 2. 식중독 원인균으로 총 62주(12.4%)가 분리되었는데 그 중에서 황색포도상구균 47주(75.8%), B. cereus 8주(12.9%), C. perfringens 7주(11.3%)로 나타났다. 3. 독소 발현 확인시험은 황색포도상구균의 경우 47주 중 25주(53.2%)에서 독소를 확인하였는데 A형이 22주(88.0%), A와 B형 복합주가 2주(8.0%), A와 C형 복합주가 1주(4.0%)로 나타났으며, B. cereus는 8주 중 7주(87.5%)에서 독소 생산주를 확인하였으나, C. perfringens는 7주 모두 독소를 생산하지 않은 것으로 나타났다. 4. 항생제감수성 시험에서 분리된 황색포도상구균 47주는 ciprofloxacin, clindamycin, imipenem, rimethoprim/sulfamethoxazole, rifampin, vancomycin에 대해서는 100% 감수성을 나타냈으며, cefepime, chloramphenicol, cefotetan, gentamycin은 각각 91.5% 및 oxacillin(89.4%), tetracycline(87.2%)에 대해서도 높은 감수성을 관찰할 수 있었다. 항생제 내성은 ampicillin(91.5%), erythromycin(42.6%) 및 penicillin(95.7%)에서 매우 높게 나타났다. 2개 이상의 항생제 다제내성을 보인 균주는 총 44주였는데, 2제 다제내성 18주(40.9%), 3제 다제내성 15주(34.1%), 4제 다제내성 7주(15.9%), 5제와 6제 다제내성 각각 1주(4.5%)로 나타났다.
