This can cause an allergic reaction called anaphylaxis, which is when the body releases chemicals to fight off the food. One of these chemicals is histamine. Histamine causes the body to release hives. Hives can take up to an hour to develop after consuming a food allergen, but they usually appear within 30 minutes.
