Description
The method is intended for the quantitative determination of paralytic shellfish toxins (PST) in mussels, softshell clams, sea scallops, and oysters. The method determines the concentrations of individual PSTs, including saxitoxin (STX), neosaxitoxin (NEO), gonyautoxins-1 to -5 (GTX1 – 5), decarbamoylgonyautoxins-2 and -3, (dcGTX2-3), decarbamoylsaxitoxin (dcSTX), and N-sulfocarbamoylgonyautoxin-2 and -3, (C1 and C2), in edible issues, as well as the total toxicity of the test samples above 0.10 mg STX dihydrochloride equivalents/kg of tissue (mg STX∙diHCl/kg).
This method is validated collaboratively under the auspices of AOAC INTERNATIONAL and corresponds to AOAC 2011.02.
