Maciag MC, Sheehan WJ, Bartnikas LM, et al. - In this sub-study of the School Inner-City Asthma Study-II, researchers sought to compare the distribution of major food allergens in floor dust and table wipe samples from elementary schools, and dust samples from students’ homes. One hundred three table wipe samples and 98 floor dust samples from cafeterias and classrooms in 18 elementary schools were analyzed for milk, peanut, cashew, hazelnut, and egg by multiplex array. Food allergens were easily detectable on elementary school tables and floors, but at lower levels than in students' homes. Peanut-allergic students found detectable peanut levels in their schools to be no higher than in their homes. Due to the low levels of detectable food allergens in school environments, severe allergic reactions are unlikely.
