During the last few years the occurrence of a high percentage of esters of diarrhetic shellfish poisoning (DSP) toxins has been observed in shellfish from the Portuguese coast. Most of the commercial bivalves contain DSP toxins in ester forms, either acyl derivatives of okadaic acid (OA) or of dinophysistoxin-2 (DTX-2). The stability of these toxins in shellfish tissues and in raw methanol extracts was investigated in two different naturally contaminated species, mussel and carpet shell, over a… CONTINUE READING
