Paralytic shellfish toxins (PSTs) are naturally occurring toxins produced by some species of microscopic algae that can accumulate in filter feeding shellfish. These toxins are a threat to shellfish aquaculture and pose a serious hazard to public health when ingested. A group of scientists has developed a method using hydrophilic interaction liquid chromatography coupled to ultrahigh?performance LC tandem mass spectrometry (HILIC UHPLC–MS–MS) to determine PSTs in a variety of shellfish species as part of the Safe New Zealand Seafood Research programme.
