As Captain Jeff said Ciguatoxin is location specific. It also seems that barracuda has gotten a bad rap as any reef fish living in the effected area can have the toxin. Maybe barracuda is more likely, but Snapper, hogfish, grouper, triggerfish, amberjack, etc have all been known to cause this type of food poisoning. In any case if your tounge/mouth start to tingle or go numb while you are eating don't finish your meal. Unless, of course, you are having Beliken or One Barrel for dinner.
