With food allergies on the rise, and 15 million Americans allergic to one or more foods, chances are good that someone you work with, go to school with or are friends with will have a food allergy. According to the Centers for Disease Control and Prevention, food allergies are a growing food safety and public health concern that affects between 4 and 6 percent of young people in the U. S. Allergic reactions can be life threatening and have far-reaching effects on the individual and their families, as well as the school, college or university they attend.
