Contents
Background
- Associated with red tides, but can occur independently
- Caused by ingestion of contaminated shellfish which harbor toxin (heat stabile) producing algae
- Shellfish typically from colder waters (New England, Pacific NW, Alaska)[1]
Clinical Features
- Symptoms develop within minutes to hours of ingestion
- Typically neurologic symptoms only: Paresthesias, dizziness, ataxia. May progress to dysphagia and/or respiratory failure. [2]
- Report any suspect cases to local department of health
Differential Diagnosis
Marine toxins, envenomations, and bites
- Toxins
- Stingers
- Venomous fish (catfish, zebrafish, scorpion fish, stonefish)
- Nematocysts
- Coral reef
- Fire coral
- Jellyfish (Cnidaria)
- Portuguese man-of-war
- Sea anemones
- Seabather's eruption
- Phylum porifera (sponges)
- Bites
- Infections
Evaluation
- Based on symptoms plus history of shellfish ingestion
Management
- Supportive. Some cases may require intubation / mechanical ventilation
Prognosis
- Mortality up to 12% if untreated [3]
- Symptoms usually self resolved within hours to days
