T61.11
Scombroid fish poisoning, accidental (unintentional)
Clinical Classification Guidelines
Medical Intelligence & Overview
Scombroid fish poisoning, classified under ICD-10 code T61.11, is a foodborne illness caused by eating certain types of fish that have improperly stored or preserved. This condition results from the ingestion of histamine-rich fish, which can lead to allergic-like symptoms. It often occurs accidentally, making it a common concern for those consuming seafood, especially in unregulated or improperly handled seafood environments.
Causes & Symptoms
Clinical Causes: Eating improperly stored or spoiled fish, particularly species like tuna, mackerel, bonito, and other dark-meat fish. Failure to refrigerate fish promptly after catching or purchase, allowing bacteria to grow and convert histidine to histamine. Inadequate processing or handling of fish before sale or consumption. Consumption of fish that has experienced temperature abuse during storage or transportation.
Key Symptoms: Facial flushing and rash Headache or dizziness Nausea and vomiting Diarrhea Burning or peppery taste in the mouth Swelling or tingling sensation in the face or neck Abdominal cramps Palpitations or rapid heartbeat Difficulty breathing in severe cases
Diagnostic & Treatment
Diagnosis Path: Diagnosis of scombroid fish poisoning is primarily based on the patient's recent history of seafood consumption and clinical presentation. Laboratory testing of fish samples may reveal elevated histamine levels, confirming the diagnosis. Blood tests are generally supportive but are not routinely necessary. Healthcare providers may differentiate this condition from allergic reactions or other foodborne illnesses through patient history and symptomatology.
Treatment Protocols: Treatment mainly involves supportive care to relieve symptoms. Patients are advised to rest and stay hydrated. In more severe cases, antihistamines may be administered to counteract allergic-like symptoms such as rash, flushing, or difficulty breathing. In rare instances, corticosteroids and epinephrine may be used for severe reactions. Prevention strategies include proper handling, refrigeration, and avoiding fish that shows signs of spoilage.
