Detection of the marine toxins okadaic acid and domoic acid in shellfish and phytoplankton in the Gulf of Mexico.
Liquid chromatographic analyses of extracts from shellfish and phytoplankton from the Gulf of Mexico indicated the presence of the marine toxins okadaic acid (0.162 microgram/g shellfish) and domoic acid (2.1 pg/cell phytoplankter). These toxins are causative agents of diarrhetic shellfish poisoning (DSP) and amnesic shellfish poisoning (ASP), respectively. The presence of DSP and ASP toxins in a region with no previous record of outbreaks may indicate a potential for human poisoning under conditions appropriate for accumulation of these toxins in shellfish.
