Abstract

To evaluate bacteriological and toxicological safety, the hygienic indicator bacterium and paralytic and diarrhetic shellfish toxins in the shellfish produced in the Kamakman Area from 2012 to 2016 were investigated. Fecal coliforms and E. coli of all 194 oyster samples tested did not exceed 230 MPN/100 g. The geometric mean of the fecal coliform analyzed with the oyster samples of harvesting period was 19.6 MPN/100 g, which was more stable than the non-harvesting period (26.5 MPN/100 g). For the toxicological evaluation of the Kamakman Area, 77 oyster samples and 350 mussel samples as an indicator were analyzed. Paralytic shellfish toxins were detected very low in the range of $40{\sim}46{\mu}g$/100 g in 13 mussel samples during late April and early June, but not in oyster samples. Diarrhetic shellfish toxin was detected in 2 of 180 samples, but it was found to be below the regulation value (0.16 mg OA equ./kg). Based on the bacteriological studies, it was confirmed that the shellfish produced in Kamakman area meets the standard of shellfish hygiene of the Food Sanitation Act and meets the Grade A of the shellfish production area of EU. As the results of the paralytic and diarrhetic shellfish toxin evaluation, it was confirmed that the Kamakman Area is also toxicologically safe for shellfish production.

본 연구는 2012년부터 2016년까지 전남 가막만해역에서 생산되는 패류에 대하여 위생지표세균, 마비성 및 설사성패류독소를 분석하여 세균학적, 독물학적 안전성을 평가하고자 하였다. 총 194점의 굴 시료에서 분변계대장균과 대장균을 분석한 결과 모두 230 MPN/100 g을 초과하지 않았다. 굴 수확시기 동안 분석한 분변계대장균의 기하학적 평균치는 19.6 MPN/100 g으로 비수확시기(26.5 MPN/100 g) 보다 안정적인 것으로 나타났다. 가막만해역의 독물학적 평가를 위해 굴 77개 시료와 패류독소 지표종인 지중해담치 350개 시료에 대한 분석을 실시하였다. 마비성패류독소는 4월말부터 6월초 사이에 지중해담치 13개 시료에서 $40{\sim}46{\mu}g$/100 g 범위로 매우 낮게 검출되었으며, 굴 시료에서는 전혀 검출되지 않았다. 설사성패류독소는 총 180개 시료 중 2개 시료에서 검출되었으나, 기준치에 미치지 못하는 것으로 확인되었다. 따라서 가막만해역에서 생산되는 패류의 세균학적 안전성을 평가한 결과, 식품위생법의 패류 위생기준에 적합하였고, EU의 패류생산해역 A등급 기준에 부합하는 것으로 확인되었다. 또한 마비성 및 설사성패류독소는 기준치보다 매우 낮은 수준으로 검출되어 독물학적 안전성이 확보된 패류생산해역으로 평가되었다.
