Shellfish poisoning includes four syndromes that share some common features and are primarily associated with bivalve molluscs (such as mussels, clams, oysters and scallops.) [1] As filter feeders, these shellfish may accumulate toxins produced by microscopic organisms, such as cyanobacteria, diatoms and dinoflagellates.

Paralytic shellfish poisoning, or PSP, is caused by saxitoxin, a naturally occurring toxin that’s produced by algae. ... Treatment for severe cases may require mechanical ventilators to help ...
Paralytic shellfish poisoning, or PSP, happens after consuming shellfish contaminated with saxitoxin, which can cause gastrointestinal distress, neurological symptoms, and a sensation of ...
Saxitoxin is a neurotoxin naturally produced by certain species of marine dinoflagellates (Alexandrium sp., Gymnodinium sp., Pyrodinium sp.) and freshwater cyanobacteria (Dolichospermum cicinale sp., some Aphanizomenon spp., Cylindrospermopsis sp., Lyngbya sp., Planktothrix sp.) [1] [2] Saxitoxin accumulates in "planktivorous invertebrates, including mollusks (bivalves and gastropods ...
The Oregon Department of Fish and Wildlife said the new closures were due to “historic high levels” of a marine biotoxin known as paralytic shellfish poisoning.
Neurotoxic shellfish poisoning (NSP) is caused by the consumption of brevetoxins, which are marine toxins produced by the dinoflagellate Karenia brevis (among several others). These toxins can produce a series of gastrointestinal and neurological effects.
Diarrheic shellfish poisoning (DSP) is one of the four recognized symptom types of shellfish poisoning, alongside paralytic shellfish poisoning, neurotoxic shellfish poisoning and amnesic shellfish poisoning. [citation needed] As the name suggests, it mainly manifests as diarrhea. Abdominal pain, nausea and vomiting may also occur. [citation ...
