FALCPA (Food Allergen Labeling and Consumer Protection Act of 2004) requires that the label of a food that is fabricated from two or more ingredients declare each ingredient by its common or usual name. It can do this either in the ingredient listing or it can highlight the allergens included in the product with a "Contains" statement. However, FDA provided further guidance that if the company chooses to use the "Contains" statement, all major allergens in the product must be listed. (FDA referenced documents below).
So in this case, while the ingredient egg was in the ingredient listing, it was missed in the "Contains' statement.
