Well-known Types of Poisoning
Amnesic shellfish poisoning (ASP). This condition is caused by domoic acid, which is produced by Pseudo-nitzschia spp. diatoms (a type of microscopic algae). Razor clams are most commonly associated with ASP, but mussels, crabs, and oysters can also be contaminated with domoic acid. In addition to nausea, vomiting, cramps, and diarrhea, ASP can cause neurological symptoms: confusion, dizziness, headaches, seizures, cardiac arrhythmia, and short-term memory loss that can become permanent. Initial symptoms usually occur within a day, and neurological symptoms take closer to 48 hours. Severe cases can lead to death.
Diarrhetic shellfish poisoning (DSP). Okadaic acid produced by the dinoflagellate Dinophysis causes DSP. The symptoms of DSP are generally more mild than other forms of shellfish poisoning, and include abdominal cramps, nausea, vomiting, and diarrhea.
Neurotoxin shellfish poisoning (NSP). Breve-toxins or their analogs cause NSP, which can trigger nausea, vomiting, and slurred speech when consumed.| ← Previous | | | Next → | Single Page
