초록

본 연구는 젓갈류 식품 중 가장 많이 소비되고 있는 새우젓의 미생물 오염도 및 안전성 평가를 위하여 재래시장(3곳), 백화점(3곳), 대형할인마트(3곳) 총 9곳에서 구입한 16개 제품을 대상으로 총호기성균, 대장균군, S. aureus의 오염도와 식염 및 중금속(Pb) 함량을 조사하였다. 총호기 성균의 오염수준은 평균 $3.35log_{10}CFU/g$를 나타냈고, 판매유형별로 비교하면 재래시장이 평균 $3.71log_{10}CFU/g$로 가장 높았으며, 백화점이 $3.16log_{10}CFU/g$, 대형할인마트가 $2.84log_{10}CFU/g$ 순으로 나타났다. 대장균군 오염수준은 16개 제품 중 8개(50%) 제품에서 양성반응을 보였고 S. aureus는 모든 제품에서 검출되지 않았다. 식염의 함량은 평균 $23.8%(17,9{\sim}28.3%)$로 나타났으며 중금속(Pb)은 단 1개의 제품에서 기준치 이하인 0.02ppm이 검출되었다. 결론적으로 시중에서 판매되고 있는 새우젓의 위생 상태는 양호한 편이나 판매유형별로 비교할 때 재래시장의 위생적 관리제도가 취약함을 간접적으로 드러내면서 젓갈류에 대해서도 HACCP 수준의 위생관리 필요성을 입증하였다.

This study monitored and compared the contamination levels of total aerobic bacteria, coliform groups and S. aureus of 16 Shrimp Jeotgal (Salt Fermented Shrimp) products from 3 traditional markets (TM), 3 department stores (DS) and 3 super markets (SM) located on seoul, Korea. Moreover this study was carried out to survey the concentrations of NaCl and heavy metal (lead; Pb) of the Shrimp Jeotgal. The contamination levels of total aerobic bacteria in the Shrimp Jeotgai were $3.35log_{10}CFU/g$ as a mean and $3.71log_{10}CFU/g$ for TM, $3.16log_{10}CFU/g\;for\;DS,\;2.84log_{10}CFU/g$ for SM. The coliform groups were contaminated in 50% of Shrimp Jeotgal and it means that the hygienic control is needed urgently. S. aureus were not detected in every sample. The levels of NaCl were between 17.9 and 28.5%. Heavy metal (lead; Pb) was detected in only 1 product at the level of 0.02 ppm out of 16 products. Although microbiological contamination levels of Shrimp Jeotgal were not much high, hygienic management like HACCP is thought to be needed for the production of Shrimp Jeotgal in traditional market.
