Marine Algal Toxins

Shellfish poisonings represent a sanitary and economic problem all over the world. Virus and bacteria are mainly responsible for seafood poisonings, but, sometimes, toxins produced by dinoflagellate unicellular algae can contaminate shellfish and provoke human intoxications. The incidence of shellfish algal poisoning is around 7.5 % of all the marine food borne disease in USA and they can be life threatening.
According to the main symptoms, these intoxications can be classified as Paralytic Shellfish Poisoning (PSP), Diarrhoetic Shellfish Poisonings (DSP), Neurotoxic Shellfish Poisoning (NSP), Amnesic Shellfish Poisoning (ASP), Azaspiracid Shellfish Poisoning (AZA). Coral reef fishes are the vectors of another algal poisoning, the Ciguatera Fish Poisoning (CFP). Non diarrhogenic lipophilic toxins, such as yessotoxins (YTXs), can be detected together with okadaic acid during the usual monitoring programs for DSP. Although no human intoxication has been ascribed to YTXs so far, their toxicity is not completely clarified. Studies are in progress to determine the potential toxicological risk of this class of toxins, that represented the main problem in Adriatic Sea in the last years.
