Symptoms of ciguatera poisoning can appear within hours of consumption and may include gastrointestinal issues such as nausea, vomiting, and diarrhea. Neurological symptoms can also occur, including tingling sensations, temperature reversal (where hot feels cold and vice versa), muscle pain, and even hallucinations. In severe cases, cardiovascular symptoms such as a slow heart rate and low blood pressure may develop. It is important to note that there is no specific antidote for ciguatera poisoning, and treatment focuses on symptom management.
