'Sesame is the ninth most common food allergy among children and adults in the U.S. According to the National Institutes of Health (NIH), sesame allergy is considered common among children who already have other food allergies. According to research reported by NIH’s National Institute of Allergy and Infectious Diseases (NIAID), a study found that approximately 17 percent of children with food allergies also are allergic to sesame.'

I'm not sure whether 17% of child food allergies counts as an edge case? Food allergies are serious stuff.
