    (Society of Fisheries Technologists(India),Cochin, 2003) Kumar, K.A.; Sona, R.; Mukundan, M.K.
    Food poisoning by consumption of aquatic foods containing biotoxins of marine origin are on the increase. These toxins are structurally and functionally diverse, and many are derived from microalgae or dinoflagellates. These cause a negative impact to natural resources and economy. The toxins, which originate from shellfishes, include Paralytic Shellfish Poisoning (PSP) and Diarrhetic Shellfish Poisoning (DSP). The toxins, which occur due to consumption of fish, are ciguatera toxin and scombrotoxin. Apart from this, marine biotoxins like tetradotoxin, amnesic shellfish toxin, etc., which are fatal to human beings have been reported from different parts of the world. This paper provides an overview of the diversity of these toxins, their mechanisms of action and causative organisms.

    Seafood toxins
    (Society of Fisheries Technologists(India),Cochin, 2000) Varma, P.R.G.
    Poisoning caused by the ingestion of toxin-containing seafood has been a part of man's concern for centuries. These toxins are either naturally present in the seafood due to some bacterial action on some natural compounds present in the seafood or accumulated in them due to aquatic pollution. The seafood toxins include Paralytic Shellfish Poison (PSP), Ciguatera toxins, Tetrodotoxin (Puffer fish), Ptychodiscus brevis toxins and Scombroid related toxins. Of these, except Scombroid toxins, all other toxins are naturally present in the seafood whereas Scombroid poisoning results from improper handling and/or processing of seafoods.
