What neurological symptom is characteristic of Ciguatera Fish Poisoning (CFP)?

Hot things feeling cold and vice versa

Ciguatera Fish Poisoning (CFP) is a foodborne illness stemming from toxins accumulated by reef fish that prey on smaller organisms carrying the toxic compound. While the illness often begins with gastrointestinal distress, such as nausea and vomiting, a highly specific and notable effect involves neurological disruption. This manifests in sensory reversals, most distinctly experienced as temperature dysesthesia, where objects or sensations that should feel hot are perceived as cold, and conversely, cold sensations are interpreted as hot. Because no established cure exists for CFP, prevention through limiting intake of known carrier species like Grouper is emphasized.
