Illinois just took a big step towards protecting the 0.2% of people allergic to sesame. On July 26, Gov. J.B. Pritzker signed HB 2123, which mandates that any packaged foods indicate the presence of sesame on their labels. 

Around 150,000 children have an allergy to sesame, a study from Northwestern University shows. A proposal at the Illinois Statehouse could help parents and children avoid foods with the ingredient.
