Marine Ingested Poisons and Infections

Scombroid is a condition resulting from ingesting improperly preserved fish like tuna or mackerel, causing symptoms such as facial flushing, severe headache, and metallic taste. On the other hand, ciguatera is caused by fish consuming toxic dinoflagellates, with barracuda being a common source. Symptoms include GI and neurologic issues, marked by temperature reversal, perioral peristhesias, and burning feet. While scombroid is treated with antihistamines, ciguatera management focuses on supportive care for neuro symptoms.
