> recent requirements to label foods containing sesame as an allergen led to more foods having sesame intentionally added, since it’s cheaper to add it intentionally and then label it than to prove the production facility and ingredients are 100% sesame free Why do they need to add the sesame? can't they just say "might contain sesame" without having to explicitly add it?
