A 28-year-old female presents with a headache, dizziness, and a tingling sensation in her mouth and extremities 24 hours after eating grilled fish. What is the most likely cause, and what are the next steps?
This patient's symptoms suggest ciguatera poisoning, a type of food poisoning caused by eating certain types of reef fish contaminated with ciguatera toxins. There's no specific antitoxin for ciguatera, and management is largely supportive, focusing on symptom relief. It's also crucial to report the incident to local health departments to prevent a larger outbreak.
