Peanuts

Peanut allergies are common, especially in children. The allergic reaction can range from a mild annoyance to a severe anaphylaxis reaction. Some sufferers are so sensitive to peanuts that air travel is out of the question because of the likelihood of being exposed to peanut dust from the snacks given in flight. People who have had a mild reaction should take precautions, as subsequent exposure can trigger more severe reactions.
