DSP toxins group and its classification are discussed. Optimal environment conditions for synthesis and source organisms are pointed. Its occurrence in food web and mollusks reaction on toxic algae presence in water are described. Mechanism of action, toxicity, tolerable contaminant levels in food, cases of poisoning and clinical presentation of intoxication are presented.

General groups of phycotoxins are discussed. Classification of phycotoxins depending on their source organisms and syndromes of poisoning is presented. Domoic acid--a member of ASP-group is described in details. The chemical structure and properties of toxin, its source organisms and occurence in food web, mechanism of action, toxicity, tolerable contaminant levels in food and clinical presentation of poisoning are presented.
