Abstract:: ... Microalgal species growing in marine and aquaculture environments can be responsible for harmful events because of their ability to produce potent natural toxins that can accumulate in edible mollusc species. Their consumption can cause severe illness and even be lethal. The European Union provides comprehensive regulations covering various general food safety aspects to manage the risk of contami ...

Abstract:: ... Lipophilic marine toxins in shellfish pose significant threats to the health of seafood consumers. To assess the contamination status of shellfish by lipophilic marine toxins in the Bohai Sea, nine species of shellfish periodically collected from five representative aquaculture zones throughout a year were analyzed with a method of liquid chromatography-tandem mass spectrometry (LC–MS/MS). Lipophi ...

Abstract:: ... The Benguela Current in the Atlantic is one of the four major upwelling systems on the Eastern boundary of the world ocean. Thus the coastal regions off Namibia are prone to high primary productivity that can lead to Harmful Algae Blooms as this nutrient rich water reaches the euphotic zone. Yessotoxins (YTXs) produced by G. spinifera were detected in Namibian phytoplankton field samples in 2011. ...

Abstract:: ... Liquid chromatography–high-resolution mass spectrometry (LC-HRMS) analysis of a Namibian strain of Gonyaulax spinifera showed the presence of a number of yessotoxins (YTXs). Principal among these were YTX (1), homoYTX (2), and a tentative hydroxylated analogue that did not correspond to any previously confirmed YTX structures. Culturing the G. spinifera strain afforded sufficient biomass for purif ...
