What are the symptoms of food poisoning?

Symptoms of food poisoning can begin hours to days after consuming the contaminated food or drink. Timing depends in part on the cause of the food poisoning and the amount of food or drink consumed. Symptoms may include:

  • Abdominal pain
  • Diarrhea
  • Fever
  • Loss of appetite
  • Nausea
  • Vomiting
  • Weakness and fatigue

Food poisoning may affect just one person or a whole group of people exposed to the contaminated food or drink. It depends on how much of the germ or toxin each person consumed and how sensitive they are to it.

What are the symptoms of food poisoning from fish?

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. These symptoms are similar to other allergic reactions. However, getting scombroid poisoning does not mean you are allergic to fish.
