Tyler Edwards, 12, of Hendersonville, Tenn., carries this epinephrine auto-injector with him because of his allergies. On Wednesday, Oct. 30, 2013, the federal government issued its first guidelines to schools on how to protect children with food allergies. The voluntary guidelines call on schools to take such steps as restricting nuts, shellfish or other foods that can cause allergic reactions, and to make sure emergency allergy medicine — such as EpiPens — are available.
