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.
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 ...
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 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 ...
Okadaic acid, C 44 H 68 O 13, is a toxin produced by several species of dinoflagellates.It is known to accumulate in both marine sponges and shellfish. [1] One of the primary causes of diarrhetic shellfish poisoning, okadaic acid is a potent inhibitor of specific protein phosphatases, and has a variety of negative effects on cells.
Before modern microbiology, foodbourne illness was not understood, and, from the mid 1800s to early-mid 1900s, was perceived as ptomaine poisoning, caused by a fundamental flaw in understanding how it worked. While the medical establishment ditched ptomaine theory by the 1930s, it remained in the public consciousness until the late 1960s and ...

If the food poisoning comes from staph-induced toxins, the illness should last no longer than a day. People tend to recover from food poisoning in one to two days, but cases can last up to two to ...
