본 연구는 국내에 수입되는 다양한 종류의 패류를 대상 으로 미관리 독소인 AZA와 AZA유사체 4종에 대한 동시 검출법을 확립하였다. 2020-2023년 기간동안 수집된 수입 패류 467샘플을 대상으로 모니터링을 수행한 결과, 러시 아에서 수입된 돌조개 2점에서 AZA-2가 정량한계 이하로 검출된 것을 확인하였다. 이는 해외의 AZA관리 기준에 미치치 않는 미량의 독소로 인체에 위해도는 없는 것으로 판단되었다. 본 연구에서 개발된 시험법으로 수입산 패류 의 안전관리에 기여할 수 있을 것이다.

Azaspiracids (AZAs) are a group of shellfish toxins that cause azaspiracid shellfish poisoning (AZP). They have been detected in mussels (Mytilus edulis) and oysters (Crassostrea gigas) in the Netherlands, Ireland, Italy, France, and the United Kingdom. In this study, we aimed to develop a method for the simultaneous detection of AZAs using ultra-highperformance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). Simultaneous analyses of AZA-1, AZA- 2, AZA-3, AZA-4, and AZA-5 were conducted according to AOAC ISO 17025 guidelines. Between 2020 and 2023, 467 imported shellfish were purchased from retail and wholesale markets in Korea. However, none of the samples tested positive for AZA-1, AZA-3, AZA-4, or AZA-5. Only two Arca avellana imported from Russia were positive for AZA-2 above the limit of detection (LOD) but below the limit of quantification (LOQ), with concentrations of 0.68 and 0.71 ng/g, respectively. This study found that the prevalence of AZA-2 was very low in shellfish imported into Korea.
