ResumenOutbreaks of paralytic shellfish polsoning (PSP) from consumption of toxic shellfish are common In all over the world and specially in the northern hemisphere. In Spain, poisonings occur mainly during late summer and early autumn (September-November) and are associated with abundance of planktonic marine dinoflagellates. Although 14 species of shellíish have been shown to became toxic, blue mussels accumulate the largest amounts of toxin in the shortest time. Features of poisonings, including symptoms, levels of human sensitivity to shellfish poison, treatment snd prevention as well as methods for measuring shellfish toxicity are described and factors affecting accuracy of mouse biossays are reviewed. Toxin in live shellfish can be reduced or eliminated if they are transplanted to nontoxic areas or subjected to sudden changes in salinity and temperature. Home cooking and commercial canning each reduce shellfish toxicity by 70-90 % and storage of toxic canned shellfish further reduces their toxicity. A control program to reduce risks of potsoning must involve: classification of shellfish producing areas according to patterns and levels of toxin accumulation; year-round monitoring of toxicity in seriously affected areas; closures and patrolling of areas when toxin scores reach hazardous levels: and warning the public of dangers. The effectiveness of control schemes and the problems encountered in their implementation are discussed
