The purpose of this study was to determine the extent of domoic acid (DA) a potent neurotoxin, responsible forthe syndrome amnesic shellfish poisoning (ASP) contamination of various species of bivalve shellfish purchased from fishmarket in Korea and the implications for food safety. Liquid chromatography (LC) methods were applied to quantify DA inshellfish after sample clean-up using solid-phase extraction (SPE) with strong anion exchange (SAX) cartridges. Toxindetection was achieved using photodiode array ultraviolet (LC-UV) and electrospray ionization-mass (LC-ESI-MS). DA wasidentified in 4 bivalve shellfishes of 872 shellfishes collected from March, 2006 to October, 2007 in Korea. DA amount of 3surf clams (Mactra veneriformis) collected at Seoul, Daejeon, and Daegu were 4.13, 1.99, and 1.94mg/kg, respectively. DAamount of 1 pink butterfly shell (Peronidia venulosa) collected at Seoul was 3.02mg DA/kg. The amounts of DA that werepresent in 4 bivalve shellfishes were within EU guideline limits for sale of shellfish (20mg DA/kg).
