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.
Shellfish containing 80 or more micrograms of saxitoxin per 100g of edible shellfish tissue are deemed to be unsafe for human consumption. [16] Currently, there is no antidote for PSP neurotoxins. Most PSP patients suffer only minor symptoms, these lasting until the toxin is eliminated from the body.
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.

PSP is the most common and severe form of shellfish poisoning and is caused by neurotoxins, called saxitoxins or paralytic shellfish toxins, that are naturally produced by marine algae, called ...
Diagnosis of NSP is made based on clinical presentation as well as history findings including recent consumption of shellfish. On average, symptoms begin 3-4 hours after consumption, but can begin anywhere from several minutes to 18 hours afterward. [4] Symptoms typically include neurologic and gastrointestinal issues including: [4] [6] nausea ...

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.
