This study evaluated the sanitary state of seawater and shellfish in Yongnam-Gwangdo area from January 2014 to
December 2016. The sampling stations for sanitary survey in Yongnam-Gwangdo area were composed of 41 seawater
stations and 5 oyster Crassostrea gigas stations. The samples were collected monthly at each station. Shellfish-borne
disease is associated with bacteria and viruses in the presence of fecal coliforms. Bacteriological pollution levels
of shellfish increase with seawater quality. Therefore, fecal coliforms are very important criteria for evaluating the
safety of fisheries in coastal areas. The geometric mean and the estimated 90th percentile ranges of total and fecal
coliforms for seawater were 1.8-11.7, 2.8-233.6, <1.8-6.7 and 1.8-100.2 MPN/100 mL, respectively. The range of E.
coli levels for oysters was <20-1,300 MPN/100 g. Based on various standards, the sanitary condition in Yongnam-
Gwangdo area was evaluated as follows: clean area (Korean criteria), conditionally approved area (US criteria) and
class B (EU criteria).
