The stations of sanitary survey in Chilcheondo area were composed of 28 seawater station, 3 oyster (Crassostrea gigas) and 1 mussel (Mytilus galloprovinciallis). The samples were collected monthly at each station. The range of Fecal coliform, geometric mean and 90th percentile for 840 seawater samples were < 1.8-35,000 MPN/100 mL, < 1.8-3.3 and 1.8-34 MPN/100 mL, respectively and in addition to seawater in the Chilcheondo area satisfied as level of designated area according to Korea criteria and approved area according to US criteria. Also the range of Fecal coliform and E. coli for 88 oyster samples and 30 mussel samples were <18-35,000 and <18-9,200 MPN/100 g, respectively. The bacteriological quallity of shellfish collected from Chilcheondo area meets the standard value based on shellfish hygiene of the Food Sanitation Act of Korea and the Grade B according to the classification of shellfish harvesting areas of European Union.
