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.
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 ...
There is no antidote to paralytic shellfish poisoning. However, with proper medical care, most patients will survive. The most important in treatment is assistance of the patient with ventilation. [1] Also alkaline and sodium-containing fluids can be used to block the effect of paralytic shellfish toxins on nerve conduction. [1]
Paralytic shellfish poisoning, or PSP, happens after consuming shellfish contaminated with saxitoxin, which can cause gastrointestinal distress, neurological symptoms, and a sensation of ...
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 oysters and bay clams involved in the warning were harvested from certain growing areas in Oregon and Washington.
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]
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 ...
