However, new findings published in Clinical and Translational Allergy discovered that children who are allergic to peanuts are actually much more likely to be exposed to peanuts in their own home than at school.
Researchers at the University of Montreal followed 1,941 children of all ages who were already diagnosed with a peanut allergy. These children were examined for an average of 2.9 years and during the observational period 567 unintended exposures occurred in 429 of the participants.
Of the accidental exposures, 37 percent happened in the child's own home. Other people's homes (14.3 percent) and restaurants (9.3 percent) also accounted for a portion of the exposures.
The number of exposures that happened at schools or daycares, on the other hand, were much fewer: just 4.9 percent occurred at peanut-free facilities and 3 percent happened where peanuts are allowed. Researchers believe there was little difference between schools that prohibit peanuts and those that don't because schools that allow peanuts have an increased awareness of the issue. Furthermore, according to the study, "peanut-free policies may create a false sense of security and foods brought to such facilities may inadvertently contain peanuts and children who are allergic may believe that it is safe to share foods as they believe they are guaranteed to be peanut free."
