A comparative analysis of methods (LC-MS/MS, LC-MS and rapid test kits) for the determination of diarrhetic shellfish toxins in oysters, mussels and pipis
Rapid methods for the detection of biotoxins in shellfish can assist the seafood industry and safeguard public health. Diarrhetic Shellfish Toxins (DSTs) are produced by species of the dinoflagellate genus Dinophysis , yet the comparative efficacy of their detection methods has not been systematical...
