To evaluate bacteriological and toxicological safety hygienic indicator bacterium and paralytic and diarrhetic shellfish toxins in the shellfish produced in the Hansan·Geojeman 2013-2017 were investigated. Fecal coliforms were <18∼330 MPN/100g in 404 oyster samples. But all samples tested, did not exceed 230 E. coli MPN/100g. Geometric mean of the E. coli for oyster samples collected during major shellfish production period was 24.3 MPN/100g, considered 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 the Grade A, according to the classification of shellfish harvesting areas of European Union. For toxicological evaluation of the 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 exceed the 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 results 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 survey was continuously requested for the food safety management of shellfishes.
