초록
This study analyzed domoic acid (DA), the causative agent of amnesic shellfish poisoning (ASP), in shellfish produced in Jinhae Bay, Korea. From January 2018 to December 2020, samples were collected at least once a month from 10 sites in Jinhae bay. This included 170 mussels Mytilus galloprovincialis and 241 oysters Crassostrea gigas. Domoic acid was detected in some samples in collected 2018 and 2019; however, all levels were significantly below the regulatory level of 20 mg/g. Domoic acid was not detected until 2020.Moreover, the detection trend of domoic acid did not show a clear correlation with the shellfish species or season. Calculation of body exposure to domoic acid through shellfish consumption showed that it was below the health-based guidance values in all cases. These results can be used as basic data on domoic acid in shellfish produced in shellfish growing areas and as policy data for the supply of safe seafood. In addition, considering the possibility of changes in marine biotoxins due to changes in aquatic environments, continuous monitoring is necessary.
