This document describes and harmonizes detection methods of diarrheic (DSP) and paralytic (PSP) phycotoxins, for the laboratories of the Direction of Coastal Environment of IFREMER, which work in the framework of the French Phytoplankton and Phycotoxins Monitoring Network. These toxins, produced by a few phytoplankton species which regularly occur in sea water, accumulate in shellfish, which become toxic. Analysis is performed on an extract of digestive gland (DSP), or of total flesh (PSP), of shellfish. The described methods are meuse-tests, which are, at the present time, the only methods available to be used in the framework of a monitoring network. The method for diarrheic toxins is not standardized, with a threshold adapted for monitoring purposes. At...

ln November 1992, an event affecting Shellfish health received extensive media coverage: an unknown toxin had been detected in oysters from the bay of MarennesOleron (France). This phenomenon remains unexplained to this day. Since then, a growing number of observations obtained in the context of the REPHY phytoplankton monitoring network, have reported a mouse-active substance found in Shellfish and belonging to none of the known phycotoxin classes. These observations have been reported in France as weil as abroad (Canada, Norway, Ireland, New Zealand ... ). Mice treated intraperitoneally with the DSP screening test- exhibit neurological symptoms with disorders of the central nervous system leading to early death (within 5 to 10 minutes). Several hundred...
