There are two types of food poisoning you can get from eating fish. They are ciguatera poisoning and scombroid poisoning. The first symptoms of ciguatera poisoning include abdominal cramps, nausea, vomiting, and diarrhea. Symptoms can then progress to headache, muscle aches, and skin that is itchy, numb, or tingly. You may notice a change in your ability to feel hot or cold temperatures.
For example, you may think something feels hot when it is actually cold. Symptoms of scombroid poisoning will usually develop 20 to 30 minutes after you eat the affected fish. They can include flushing (turning red) of the face, nausea, vomiting, hives, and abdominal pain.
