  • The toxin, known as saxitoxin, disrupts normal nerve functions and can cause paralysis and death by respiratory failure within two to 24 hours, Sea Fisheries said in a statement.

    ANC Daily News Briefing

  • The poison implicated was called saxitoxin and is thought to build up in puffers through the mollusks, clams, mussels and scallops they eat.

    undefined

  • Since rapid onset of symptoms after a meal of pufferfish could indicate saxitoxin poisoning; it is recommended to call the local poison control center and go to the nearest hospital ED for evaluation. 9

    Fish poisonings and envenomations

  • The toxin produced by the red tide blooms, called saxitoxin, causes PSP by blocking sodium conductance and neuronal transmission in skeletal muscles. 8 Saxitoxin is not destroyed by cooking or freezing; it is heat and acid stable and does not alter the taste or smell of food.

    Fish poisonings and envenomations

  • Tetrodotoxin (a toxin in frogs, puffer fish and other invertebrates) and saxitoxin (a cause of shellfish poisoning) blocks sodium channels.

    Neurotoxicity

  • Naturally-occurring toxins that can be used as weapons include ricin (WA), SEB (UC), botulism toxin (XR), saxitoxin (TZ), and many mycotoxins.

  • Perhaps the best overview is provided in the excellent paper by C. Y. Kao, Tetrodotoxin, saxitoxin and their significance in the study of excitation phenomenon, Pharmacological Reviews 18, no.

  • In addition, our sampling detected the presence of Aphanizomenon, a previously undetected cyanobacteria, and the associated presence of cylindrospermopsin, a liver toxin and saxitoxin, a nerve toxin.

  • Algal toxins arising from the blooms include microcystin, anatoxin-a, cylindrospermopsin and saxitoxin, according to the Ohio Department of Health.
