Abstract	The dinoflagellate Alexandrium tamarense produces paralytic shellfish toxins that cause foodborne illnesses via bivalve consumption. The toxin profiles produced by A. tamarense and the toxins in the blue mussel (Mytilus edulis) were compared by high-performance liquid chromatography. Whereas the 11β-epimer toxins C2 and gonyautoxin GTX4 were predominant toxins produced by A. tamarense, but the 11α-epimer toxin GTX1 was predominant, followed by C1, C2, and GTX in blue mussel. In the early period (March 24th to April 7th) of toxin accumulation in blue mussels, the levels of the C2 and GTX4 were higher than those of C1 and GTX1. However, with an increase in intoxication time, the relative proportions of 11β-epimer toxins and 11α-epimer toxins were reversed, so that the ratios of C1 and GTX1 were 2.1–2.4 times higher than those of C2 and GTX4, respectively, until May 31st. This shifting pattern of predominance indicates that toxicity increases through a conversion process during accumulation.
