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.
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 ...
PSP affects those who come into contact with the affected shellfish by ingestion. [1] The toxins responsible for most shellfish poisonings—mainly saxitoxin, although several other toxins have been found, such as neosaxitoxin and gonyautoxins I to IV—are water-insoluble, and heat- and acid-stable. Therefore, ordinary cooking methods will not ...
The U.S. Food and Drug Administration says consumers should avoid eating shellfish from Oregon and Washington state as they may be contaminated with toxins that cause paralytic shellfish poisoning ...
Paralytic shellfish poisoning, or PSP, happens after consuming shellfish contaminated with saxitoxin, which can cause gastrointestinal distress, neurological symptoms, and a sensation of ...
[54] [55] Saxitoxins bioaccumulate in shellfish and certain finfish. Ingestion of saxitoxin, usually through shellfish contaminated by toxic algal blooms, can result in paralytic shellfish poisoning. [28] Saxitoxin has been used in molecular biology to establish the function of the sodium channel. It acts on the voltage-gated sodium channels of ...
Other potential causes such as paralytic shellfish poisoning (PSP), neurotoxic shellfish poisoning (NSP), scombrotoxin fish poisoning, and pufferfish poisoning should be excluded. [1] The reversal of hot and cold sensations is an occasional symptom of CFP that may help differentiate it from norovirus. [20]
The family of a man with a shellfish allergy who allegedly went into shock and died after being served contaminated pesto at a Las Vegas resort is suing the restaurant over his wrongful death.
