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.
DSP and its symptoms usually set in within about half an hour of ingesting infected shellfish, and last for about one day. The causative poison is okadaic acid, which inhibits intestinal cellular dephosphorylation. [1] This causes the cells to become very water-permeable and the host to profusely defecate into a high risk of dehydration.
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 ...
Paralytic shellfish poisoning, or PSP, happens after consuming shellfish contaminated with saxitoxin, which can cause gastrointestinal distress, neurological symptoms, and a sensation of ...
Symptoms included nausea, vomiting, and diarrhea for 2–5 days prior to full recovery. Analysis of the shellfish revealed five AZA analogues, AZA1-5, with most of the toxin concentrated in the digestive glands [8] [9] at levels exceeding 30 μg/g (estimated at 6 μg/g whole mussel meat). The AZAs persisted in the mussels at elevated levels for ...
They may also look, smell and taste normal, so the FDA warns customers to watch for PSP symptoms, which develop in most people within 30 minutes of consuming contained seafood.
Scombroid food poisoning, also known as simply scombroid, is a foodborne illness that typically results from eating spoiled fish. [2] [4] Symptoms may include flushed skin, sweating, headache, itchiness, blurred vision, abdominal cramps and diarrhea. [2] [5] Onset of symptoms is typically 10 to 60 minutes after eating and can last for up to two ...
Amnesic shellfish poisoning (ASP) is an illness caused by consumption of shellfish that contain the marine biotoxin called domoic acid. [1] In mammals , including humans, domoic acid acts as a neurotoxin , causing permanent short-term memory loss , brain damage , and death in severe cases.
