ICD-10: T61.01

Ciguatera fish poisoning (CFP) is a foodborne illness caused by the consumption of fish contaminated with toxins produced by marine dinoflagellates, primarily Gambierdiscus toxicus. This condition is classified under the ICD-10 code T61.01, which specifically denotes accidental (unintentional) ciguatera fish poisoning.

Clinical Description

Etiology

Ciguatera fish poisoning occurs when individuals consume fish that have accumulated ciguatoxins through the marine food web. These toxins are not destroyed by cooking or freezing, making the consumption of contaminated fish a significant health risk. Common fish species associated with CFP include barracuda, grouper, snapper, and amberjack, which are often found in tropical and subtropical waters.

Symptoms

The symptoms of ciguatera fish poisoning can vary widely and may appear within a few hours to several days after ingestion. Common clinical manifestations include:

• Gastrointestinal Symptoms: Nausea, vomiting, diarrhea, and abdominal pain are frequently reported.
• Neurological Symptoms: Patients may experience tingling or numbness in the extremities, muscle weakness, and in some cases, temperature reversal (where hot feels cold and vice versa).
• Cardiovascular Symptoms: Bradycardia (slow heart rate) and hypotension (low blood pressure) can occur, leading to further complications.
• Other Symptoms: Headaches, fatigue, and joint pain may also be present.

Diagnosis

Diagnosis of ciguatera fish poisoning is primarily clinical, based on the history of fish consumption and the presentation of symptoms. Laboratory tests are not routinely used for diagnosis, but they may help rule out other conditions.

Treatment

There is no specific antidote for ciguatera fish poisoning. Treatment is supportive and may include:

• Symptomatic Relief: Antiemetics for nausea, intravenous fluids for dehydration, and pain management.
• Monitoring: Patients may require monitoring for severe symptoms, especially cardiovascular and neurological complications.
