An allergy chart tells the reader what commonly served foods contain allergens. For example, the North Tonawanda City Schools department, New York, allergy chart shows the foods found in its cafeterias and the allergens, such as milk, eggs, peanuts, tree nuts and soy, they contain.
Some other food allergy charts from Chipotle and Moe's Southwest Grill show menu items and the allergens they contain. For example, the soft flour tortilla from Chipotle contains gluten and sulphites, while the sour cream contains milk. This chart also shows the items on the menu that are vegan and vegetarian. The food allergy chart shows that the restaurant uses no eggs, peanuts, tree nuts, shellfish or sesame in its food, notes Chipotle.
