Back in January, a school in Whitehorse launched a rarely-seen policy, which would allow peanuts and tree nuts on the premises. The decision was made after a series of consultations with both staff and families, including those with food allergies. Here in Canada, hundreds of schools have banned the presence of these products in their classrooms, as more than 500,000 children are dealing with some sort of food allergy. However, recent research has questioned the effectiveness of blanket, site-wide food restrictions. Is it time for Canada’s schools to modernize their food allergy policies? Kristy Cameron digs deeper with Dr. Samira Jeimy, a London-based allergist with the Allergy and Immunology Program at St. Joseph's Health Care.
