| It is difficult to apply sanitary standards for mollusc contamination by paralytic shellfish poisoning to animals not consumed whole. This problem is illustrated by the 1990 embargo on a Japanese shipment of frozen scallop muscle and gonad: the sanitary threshold applied to digestive gland (in Japan) does not guarantee that muscle and especially gonad are toxin-free. Accordingly, we performed experimental contaminations of scallops (Pecten maximus) from Port-en-Bessin (Normandy, France) using a toxic Japanese strain of Alexandrium tamarense. During the contamination/decontamination experiment on different tissues (digestive gland, muscle, gonad), extracts were obtained using cold acetic acid 0.1 N to maintain the perfect integrity of the toxin profile.... |

| 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... |
