What is Azaspiracid shellfish poisoning?
Azaspiracid poisoning (AZP) is a newly identified marine toxic syndrome, caused by consumption of mussels (Mytilus edulis) contaminated by the dinoflagellate Protoperidinium crassipes [18]. The typical symptoms of AZP resemble those of DSP, whereas neurotoxic symptoms are also observed in some poisoning incidents.
What shellfish is common with shellfish intoxication?
AMNESIC SHELLFISH POISONING Implicated shellfish include mussels, scallops, razor clams, and other crustaceans.
What does Brevetoxin cause?
Neurologic signs and symptoms include paresthesias, reversal of hot and cold temperature sensation, vertigo, and ataxia. Inhalational exposure may cause respiratory symptoms such as cough, dyspnea and bronchospasm (1-4). Brevetoxin can also cause illness in aquatic wildlife.
How long does shrimp poisoning last?
Ciguatera poisoning symptoms typically resolve within several days, but may last up to 4 weeks. The symptoms of ciguatera poisoning may resemble other medical conditions. Always talk with your healthcare provider for a diagnosis.
What kind of food poisoning comes from shrimp?

Is shrimp a shellfish?
Marine animals in the shellfish category include crustaceans and mollusks, such as shrimp, crab, lobster, squid, oysters, scallops and others.
What does brevetoxin do to animals shellfish and to humans?
Brevetoxins are neurotoxins that bind to voltage-gated sodium channels in nerve cells, leading to disruption of normal neurological processes and causing the illness clinically described as neurotoxic shellfish poisoning (NSP).
How long does neurotoxic shellfish poisoning last?
ONSET/DURATION: Onset of symptoms occurs within minutes to hours, definitely within 24 hours, of consuming brevetoxin-contaminated shellfish. Duration of the illness is generally short, lasting from a few hours to several days.
Why do I feel sick after eating shrimp?
Shellfish allergies are most often the immune system’s response to a protein found in shellfish muscles called tropomyosin. Antibodies trigger the release of chemicals such as histamines to attack the tropomyosin. The histamine release leads to a number of symptoms that can range from mild to life-threatening.

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.
How common is neurotoxic shellfish poisoning?
Neurotoxic shellfish poisoning is a rare disease that occurs after consumption of molluscan shellfish contaminated with brevetoxins. Shellfish harvested along the Gulf of Mexico during or right after a red tide are at risk of contamination with brevetoxins produced by the dinoflagellateKarenia brevis.
How is brevetoxin treated?
There are no specific antidotes for brevetoxins. Treatment involves mostly supportive care. Brevenal, a natural antagonist of brevetoxin produced byK. brevis, may be used as a form of treatment in the future.
