When immediate care is needed
Fast facts
The immune system normally protects people from germs. In people with food allergies, the immune system mistakenly responds to food as if it were harmful.
The symptoms and severity of allergic food reactions can differ among people. Symptoms and severity can also be different for one person over time.
Early and quick recognition and treatment can prevent serious health problems or death. Eight foods or food groups account for most serious allergic reactions in the United States:
- Milk
- Eggs
- Fish
- Crustacean shellfish
- Wheat
- Soy
- Peanuts
- Tree nuts
Responding to food allergy emergency
It is not always easy or possible to avoid certain foods. Staff in schools, out-of-school time, and early care and education programs (ECE) should develop plans for food allergies. The plans should outline how to prevent an allergic reaction and respond to a food allergy emergency, including anaphylaxis.
What CDC is doing
CDC along with the U.S. Department of Education, several federal agencies, and many stakeholders developed Voluntary Guidelines for Managing Food Allergies in Schools and Early Care and Education Programs. The guidelines have information and recommendations for five priority areas. Each priority area should be addressed in each school’s or ECE program’s Food Allergy Management Prevention Plan:
- Ensure the daily management of food allergies in individual children.
- Prepare for food allergy emergencies.
- Provide professional development on food allergies for staff members.
- Educate children and family members about food allergies.
- Create and maintain a healthy and safe educational environment.
