현대인들은 가정생활과 직업환경 속에서 다양한 종류의 전자기파에 노출되며 전자기파 노출에 따른 생체위해성은 공중보건학적으로 중요한 이슈로 대두되었다. 현재까지 많은 체외 및 체내실험 결과에서 전자기파 노출이 세포대사, 내분비, 면역, 신경, 생식, 태아발달에 영향을 미치는 것으로 보고되었다. 세포나 개체 수준에서 시행된 실험연구에서는 전자기파 노출에 의해 세포내부 자유기의 증가, DNA 손상과 암발생, 발생기형, 생식기능 저하가 나타난다. 역학조사결과 전

The consumption of “ready-to-eat” agricultural products is recently increasing and the safety of these agricultural products is forefront of public concerns. The 120 samples of paprikas, strawberries and tomatoes, which are the representative exported agricultural products, were purchased at the department stores and discount stores in Daejeon. And we determined the microbiological and parasitological contamination level of these agricultural products using culture media, multiplex PCR, commercial bacterial detection kit and microscopy, and also evaluated the decontamination method. Mean counts of total aerobic bacteria from these agricultural products ranged from 1.3×104 CFU/g to 1.8×105 CFU/g, and mean counts of coliforms ranged from 1.4×103 CFU/g to 9.6×103 CFU/g. There was no significant difference in the level of bacterial contamination between the agricultural products from department stores and the ones from discount stores. Strawberry showed the highest contamination level for the bacteria and we also found the unidentified parasite eggs. Enterobacter cloacae was the most frequently isolated bacteria strain, but no food poisoning pathogenic bacteria except Staphylococcus aureus was isolated from the products by multiplex PCR. Compared to unwashed products, tab water-washed ones showed 80% decrease of the counts of total aerobic bacteria on the agricultural products, and the rates decreased more by incorporating detergent or ultrasonic wave treatment. We concluded that the biological contamination levels among paprikas, strawberries and tomatoes were the highest in strawberries, but there were not significant difference according to distribution systems.

최근 친환경 농산물에 대한 소비자의 관심이 높아짐에 따라서 이들 친환경 농산물의 안전성에 대한 검증 요구가 증대되고 있다. 본 연구는 26종의 엽채류 및 4종의 과채류를 대상으로,재배유형(재래농법 및 유기농법)및 유통 경로 (대형마트 및 유기농전문점)에 따른 세균 및 기생충의 오염을 선택 감별배지, 자동 세균 동정 시스템, 현미경 관찰로 조사하였다. 수세하지 않은 농산물에 부착한 세균 집락 수는 농산물 균질액 1 mL(농산물 0.1 g) 당 범
