Food Allergies

Children eating breakfast at school

Approximately six million children in the U.S. have one or more food allergies, and among children with food allergies, 16 to 18 percent have experienced a reaction at school. At any time, school staff may need to respond to a food allergy emergency — whether in the classroom or cafeteria, or on the playground, athletic field, or school bus. That’s why it’s important for educators to know about food allergies and understand their role in helping to prevent and respond to allergic reactions in schools.

Food allergy is an abnormal response to a food, triggered by the body’s immune system. In individuals with food allergies, the immune system mistakenly responds to a food (known as the food allergen) as if it were harmful, triggering a variety of negative health effects.

Nuts can cause allergic reactionsCommon food allergens found in the school environment include:

  • milk
  • eggs
  • peanuts
  • soy
  • wheat
  • tree nuts (e.g., almonds, walnuts, pecans)
  • fish
  • shellfish (e.g., crab, lobster, shrimp)

Non-food items can contain food allergens such as modeling clay and paper mache (may contain wheat), crayons (may contain soy), and finger paints (may contain milk or egg whites).

Allergic reactions vary from mild to severe and can appear within minutes to hours after exposure to a food allergen. Common symptoms include swollen lips/tongue/eyes, itchy/flushed skin, rash, hives, wheezing, coughing, and shortness of breath. More serious symptoms include pale or blue skin color, weak pulse, dizziness, fainting, confusion, shock, drop in blood pressure, and loss of consciousness.

Over one million students will experience food allergy reactions at school each year

Anaphylaxis is a severe allergic reaction that happens quickly and may cause death. It may cause a student to stop breathing or experience a dangerous drop in blood pressure. Epinephrine is the primary treatment for severe allergic reactions, and early administration improves the chances of survival and quick recovery. Further information on anaphylaxis can be found on our website here.

Health is a team effortManaging food allergies in schools is a team effort involving all school staff, parents/guardians, and health care providers. Each member of the school community should receive training on how to prevent and respond to food allergic reactions as part of the overall school safety training.

The Centers for Disease Control and Prevention (CDC) also has some great resources on food allergies, including their Tool Kit for Managing Food Allergies in Schools.
