초록

본 연구에서는 우리나라의 새꼬막 주 생산해역인 전남 여자만에 대하여 해수 및 패류의 세균학적 분석결과를 근거로 위생상태를 평가함으로써 동 해역의 위생안전성 확보를 위한 기초자료를 제공하고자 하였다. 또한 본 연구결과를 적용하여 우리나라의 정착성 수산물 등급기준에 따른 해역분류 및 한국패류위생계획에 근거한 '수출용패류생산지정해역'으로의 가능성을 평가하고자 하였다. 2014년 1월부터 2016년 6월까지 여자만에 설정한 50개소의 조사정점별 해수의 위생지표세균 조사결과, 대장균군 및 분변계대장균 수의 범위는 각각 <1.8~5,400 및 <1.8~350 MPN/100 mL으로 분석되었으며 이는 우리나라의 '정착성 수산동식물 생산해역 등급설정 기준'(MOF, 2013a)에 따라 청정해역의 기준에 충족하는 것으로 평가되었다. 수출용패류생산지정해역으로 지정을 위해서는 미국이나 유럽연합 등의 기준을 충족하여야 하며 본 조사결과 미국의 National Shellfish Sanitation program (U.S. FDA, 2016)에 따라 해수의 수질은 허가해역에 적합한 것으로 평가되었으나, 여자만은 주변에 오염원이 산재해 있고 강우의 영향을 받을 수 있으므로 오염원 관리가 수반되어야 하는 조건부 허가해역에 적합한 것으로 평가되었다. 또한, 유럽연합의 Regulation (EC) No 854 (European Commission, 2004)에 근거하여 여자만의 패류(새꼬막)는 계절적 또는 시기적 영향을 받는 것으로 확인되어, 해역 분류기준 중 Class B에 부합하는 것으로 확인 되었으며 시기에 따른 분류(6~10월은 Class B, 11-5월은 Class A)도 가능 할 것으로 평가되었다. 아울러 여자만의 위생안전성을 확보하고 외국으로 패류를 수출하기 위해서는 앞으로 오염원관리계획 수립을 위한 체계적인 오염원 현황파악 및 영향평가가 수반되어야 하며, 패류에 대한 중금속 및 패류독소 등의 추가조사 또한 필요할 것으로 사료된다.

This study evaluated the sanitary state of seawater and shellfish in Yeoja bay from January 2014 to June 2016. The sampling stations for sanitary survey in Yeoja Bay was composed of 50 stations for seawater and 4 stations for ark shell and the samples have been collected monthly at a stated date. The total and fecal coliforms in seawater and Escherichia coli (E. coli) in shellfish were investigated as sanitary indicator bacteria, respectively. The geometric mean and the estimated 90th percentile ranges of total and fecal coliforms for seawater were <1.8-3.9, <1.8-2.6 and <1.8-29.7, <1.8-9.3 MPN/100 mL, respectively. The range of E. coli levels for ark shell were <20~330 MPN/100 g. The sanitary state in Yeoja bay was evaluated clean area according Korea criteria and conditionally approved area according US criteria and Class B area according EU criteria.
