What is diarrhetic shellfish poisoning?
Diarrhetic (or diarrheal) shellfish poisoning occurs from ingesting shellfish (such as mussels, cockles, scallops, oysters and whelks) that contain toxins. These toxins cause gastroenteritis symptoms, such as watery diarrhea. … Shellfish harvested in BC coastal waters can sometimes be contaminated with this toxin.

Symptoms usually start as soon as a few minutes after eating a food and as long as two hours after. In some cases, after the first symptoms go away, a second wave of symptoms comes back one to four hours later (or sometimes even longer). This second wave is called a biphasic reaction.
What species are affected by neurotoxic shellfish poisoning?
Although not fatal to humans, neurotoxic shellfish poisoning is known to kill fish, invertebrates, seabirds, and marine mammals (e.g., manatees). It is caused by the brevetoxin family of toxins (brevetoxin + 10 related compounds9 produced by the dinoflagellate Karenia brevis (= Gymnodinium breve).
What happens if you eat bad shellfish?
After eating contaminated clams or mussels, you will most likely experience nausea, vomiting, and diarrhea. These symptoms will be followed soon after by strange sensations that may include numbness or tingling in your mouth, headache, dizziness, and hot and cold temperature reversal.

What are possible causes of neurotoxic shellfish poisoning?
CAUSATIVE AGENT: Neurotoxic Shellfish Poisoning (NSP) is caused by the consumption of molluscan shellfish (e.g. clams, oysters, coquinas, mussels and other filter feeders) contaminated with brevetoxins, which are produced by a marine dinoflagellate called Karenia brevis.
What is the cause of paralytic shellfish poisoning?
Paralytic shellfish poisoning (PSP) is a serious illness caused by eating shellfish contaminated with dinoflagellate algae that produce harmful toxins. Some of these toxins are 1,000 times more potent than cyanide, and toxin levels contained in a single shellfish can be fatal to humans.
How do you test for paralytic shellfish poisoning?

Which toxin is responsible for paralytic shellfish poisoning?
PSP is a marine toxin disease with both gastrointestinal and neurologic symptoms reported worldwide. It is caused predominantly by the consumption of contaminated shellfish. Gonyaulacoid dinoflagellates are the source of PSP marine toxins.
How can shellfish poisoning be prevented?

Can fish poisoning kill you?
