Saxitoxin (STX) is a potent neurotoxin and the best-known paralytic shellfish toxin. Ingestion of saxitoxin by humans, usually by consumption of shellfish contaminated by toxic algal blooms, is responsible for the illness known as paralytic shellfish poisoning (PSP).
Paralytic shellfish poisoning, or PSP, happens after consuming shellfish contaminated with saxitoxin, which can cause gastrointestinal distress, neurological symptoms, and a sensation of ...
It is among the group of Alexandrium species that produce toxins that cause paralytic shellfish poisoning, and is a cause of red tide. [2] Alexandrium catenella is observed in cold, coastal waters, generally at temperate latitudes. [3] These organisms have been found in the west coast of North America, Japan, Australia, and parts of South Africa.
