Well...the DR is ripe with wives tales. I was told the wives tale was "don't eat oysters in months with the letter "r"." That said, CIGUATERA is a reef (hence TROPICAL sea) disease ...and there's no OYSTERS growing in the DR....
Tell ya what, let's try it...next month is MAY, go eat a large Dominican reef caught PARROTFISH and let me know how you make out.
