And because we all like to eat a lot of fish, I know more and more people with very high mercury levels in their systems these days. The doctors blame it on all the raw tuna we eat, along with a few nice chunks of swordfish and tilefish too. And don’t forget about when they pass around those fish sticks in the Bahamas, Belize, Mexico or offshore hot spots; you never know what you are getting. It could be barracuda, giant grouper or big hogfish — all species that are known to carry ciguatera. That is how I caught it, and I know quite a few other fishermen who got it too. It’s not something you want to “catch” because there is no cure, and the doctors really don’t know much about it.
