After eating a problem food allergen, how long does it take to show up in body symps? and how long does it take to exit system? thanks dr!

2 hours: Most allergic responses occur within 2 hours although reaction to red meat may not come on until 3-6 hours later. Most allergic responses from food should subside in less than a day. As for how long traces of the food may remain in your body, it would depend on the kind of food.
