A recent survey has determined that children and teens who suffer from severe, food-related allergies may feel that they are in danger at school.

Dozens of students interviewed by Canadian researchers indicated that they worried about their schools’ level of knowledge about food allergies, as well as about what administrators had or had not done to address the issue. Their fears were published in a recent issue of the journal Risk Analysis.

All participants had allergies to common foods like eggs, peanuts, shellfish and milk, for which they constantly carried portable epinephrine injectors in case of a sudden and severe reaction.

The majority of those surveyed said that what frightened them most was the thought of people not knowing how easily food allergies can make a common situation into a life-threatening one.

The study’s authors concluded that findings like these should be accounted for when creating public school food policies.

According to data published in the study, an estimated 200 children in the U.S. die from food allergies every year.

More than 12 million Americans have food allergies, the Food Allergy and Anaphylaxis Network states.
