Abstract

To evaluate bacteriological and toxicological safety hygienic indicator bacterium and paralytic and diarrhetic shellfish toxins in the shellfish produced in Hansan Geojeman 2013-2017 were investigated. Fecal coliforms were < 18~330 MPN/100 g in 404 oyster samples. But all samples tested, did not exceed 230 E. coli MPN/100 g. Geometric mean of E. coli for oyster samples collected during major shellfish production period was 24.3 MPN/100 g, considerde stable results. Bacteriological quality of oysters collected from Hansan Geojeman meets the standard value based on shellfish hygiene of the Food Sanitation Act of Korea and also meets Grade A, according to classification of shellfish harvesting areas of the European Union. For toxicological evaluation of Hansan Geojeman, 532 oyster samples and 268 mussel samples as an indicator, were analyzed. Paralytic shellfish toxins were detected in the range of 0.42~2.29 mg/kg in eight mussel samples, and exceeded criteria in three samples from early to late April 2013. Diarrhetic shellfish toxin was detected in three of 120 samples, but it was revealed to be under regulation value (0.16 mg Okadaic Acid equ./kg). As a result of toxicological evaluation, paralytic and diarrhetic shellfish toxins were not detected in oyster samples, but it was found that mussel as an indicator species, exceeded the threshold value of paralytic shellfish toxin. Accordingly, sanitary surveys were continuously requested for food safety management of shellfish.

본 연구는 2013년부터 2017년까지 경남 한산 거제만 해역에서 생산되는 패류에 대한 위생지표세균, 마비성 패류독소, 설사성 패류독소를 분석하여 세균학적 독물학적 안전성을 평가하였다. 굴 시료 404점에 대한 분변계대장균은 < 18~330 MPN/100 g의 범위를 나타내었으나, 대장균 230 E. coli MPN/100 g을 초과한 시료는 없었다. 굴 수확시기 동안 분석한 대장균의 기하학적 평균치는 24.3 MPN/100 g으로 매우 낮게 나타났다. 한산 거제만해역에서 생산되는 굴의 세균학적 안전성을 평가한 결과, 식품위생법의 생식용 굴에 대한 위생기준을 만족하였고, EU의 패류생산해역 A등급 기준에 부합하였다. 한산 거제만해역의 독물학적 평가를 위해 굴 532개 시료와 패류독소 지표종인 지중해담치 268개 시료에 대한 분석을 실시하였다. 마비성패류독소는 2013년 4월에 지중해담치 3개 시료에서 1.20~2.29 mg/kg 범위로 기준을 초과하여 검출되었으나, 굴시료에서는 전혀 검출되지 않았다. 총 120개 시료에서 설사성패류독소를 분석하였으나, 정량한계 이하로 매우 낮게 나타났다. 독물학적 안전성 평가결과, 굴 시료에서는 마비성 및 설사성패류독소가 전혀 검출되지 않았으나, 지표종인 지중해담치에서는 마비성패류독소 기준치를 초과한 것으로 나타나 지속적인 모니터링과 안전관리가 요구되었다.
