T61.8

Clinical Causes: Consumption of seafood contaminated with toxins produced by certain algae (e.g., ciguatoxins, saxitoxins). Ingestion of improperly stored or handled seafood containing bacteria or toxins such as histamines (scombroid poisoning). Eating seafood that has accumulated pollutants, heavy metals, or chemical contaminants. Consumption of seafood that is not fresh or has been stored at incorrect temperatures increasing toxin production. Contact with seafood that has been exposed to environmental toxins during harvesting or processing.

Key Symptoms: Nausea and vomiting Diarrhea or abdominal cramps Headache and dizziness Sensory disturbances like tingling or numbness, especially around the lips and tongue Muscle weakness or coordination problems Flushing or a rash (particularly in scombroid poisoning) Respiratory difficulties in severe cases Severe cases may involve neurological symptoms such as confusion or vision disturbances

Diagnosis Path: Diagnosis typically involves reviewing the patient's recent seafood consumption history and presenting symptoms. Healthcare providers may perform physical examinations and request laboratory tests to identify specific toxins or bacteria in the blood, stool, or leftover seafood. In some cases, specialist tests like toxin assays or histamine level measurements are used to confirm the cause.

Treatment Protocols: Treatment aims to alleviate symptoms and prevent complications. Supportive care is the primary approach, including maintaining hydration with fluids, managing nausea and vomiting, and monitoring for neurological symptoms. In cases of severe allergic reactions or toxin exposure, hospitalization may be required, and specific medications like antihistamines or anti-toxin agents might be administered. Prevention includes proper seafood handling, storage, and sourcing from reputable suppliers to reduce risk.
