Analyzes of crabs caught in the area in question showed that these contained in part high values of DSP toxins. DSP toxins are produced by microalgae, mainly species within the genus Dinophysis and the accumulation of these in mussels is not unusual. DSP toxins in mussels mean that shellfish cannot harvest, and that it is possible issue a warning to the public that one should not eat shells from the relevant areas. (It is given weekly mussel warning under the auspices of SNT (The Norwegian Food Safety Authority). DSP toxins in bag crab, on the other hand, is apparently a whole new phenomenon. In connection with the poisoning episodes in the summer of 2002, a larger one was collected crab and mussel material for experimental studies. The goal was to identify source organisms for crab toxins, rate of accumulation, and opportunities for detoxification. Experiments were performed in the laboratory under controlled conditions. The Fisheries and Aquaculture Research Fund took an interest in the project and co-financed the project together with the Institute of Marine Research and Norway Veterinary College. The project that has been completed provides useful information about DSP toxins in crabs in case a similar episode should occur. The project must be seen as a useful one platform for further work with DSP toxins in bag crab. The issue was unknown in Norway before the summer of 2002 and more experience and knowledge is crucial to be able to provide catch and diet advice that is reliable.
