How it works in the kitchen
US food labels name the major allergens in the ingredients or in a "Contains" line. A checker can only read the words it is given: it cannot see "may contain" warnings, factory traces or ingredients hidden inside other ingredients. Always read the full label and talk to the person with the allergy.
