Ciguatera fish poisoning

Ciguatera fish poisoning is when you eat a fish that has poison in it. The poison is made by tiny organisms called algae that the fish eats. When you eat the fish, the poison can make you feel sick.

The poison can cause lots of different symptoms like feeling tired, vomiting, aching all over, or even feeling itchy. Some people might also feel like things taste funny or like they have a tingly feeling in their mouth.

The funny thing about ciguatera is that you can't tell which fish have the poison in them just by looking at them. The only way to really be sure is through special tests that scientists can do.

To avoid getting ciguatera, it's a good idea to only eat fish that you know are safe. If you're not sure, it's better to be safe than sorry and avoid eating it.
