LC/MS/MS로 패류 114건에서 설사성패독인 OA, DTX1, PTX2, YTX을 정량한 결과 110건(96.5%)에서는 설사성패독이 불검출이었으며, 굴 2건(0.004, 0.001 ${mu}g/g$), 진주담치 1건(0.001 ${mu}g/g$), 바지락 1건(0.001 ${mu}g/g$)에서 OA(Okadaic acid)가 검출되어 3.5%의 검 출률을 나타내었으며 동일 시료를 마우스시험법으로 마비성 패독을 실험한 결과 설사성 패독과의 유의성은 보이지 않았다.
Diarrhetic shellfish poisoning toxins were investigated by liquid chromatography-electrospray ionization mass spectrometry (LC-MS/MS). Okadaic acid (OA), Dinophysistoxin-1 (DTX1), Pectonotoxin2, (PTX2) and Yessotoxin (YTX) in bivalves were quantified. OA were found in four samples; mussel Mytilus edulis (0.001 ${mu}g/g$), Oyster Crassostrea gigas (0.004 and 0.001 ${mu}g/g$) and manila clam Ruditapes philippinarum (0.001 ${mu}g/g$). DTX1, PTX2, and YTX were not detected from all of the samples examined.
