Ciguetera has been around for the longest time. It is a fish intoxication due to some algae that produce a very strong toxin that is not destroyed by cooking.
I got it from a snapper that I caught myself, this was about 25 years ago. Believe me if you get it it will not pass in 6/8 hours. I was paralyzed waist up for a week had diarrhea for 5 days and for 1 year I could no eat seafood and drink alcholic beverages of any type.
