Avoid These Poisonous Fish
United States health officials are highlighting a type of food poisoning that is going unreported these days. It involves predatory fish that swim in tropical waters, such as barracuda and grouper. If you eat these fish regularly, you are at risk of “ciguatera poisoning.”
Toxins called “CTX” build up naturally in many coral reef fish, such as surgeonfish, amberjack, and snapper. The problem is that small fish eat microalgae that might have CTX on their surface. As the bigger fish eat the smaller fish, the level of toxins grows.
