Why this reading matters

For covered US labels, major allergen sources can be identified in the ingredient names or a nearby Contains statement. Precautionary cross-contact statements are voluntary; their absence is not proof of absence. US Food and Drug Administration.

What the label cannot settle

A label check cannot rule out undeclared milk or cross-contact. For a milk allergy, use your care plan and ask the maker about unresolved details.

Put the check to work

Compare the exact words and amounts on your package with the example. If a panel is missing, a photo is unreadable or the manufacturer has not disclosed a detail, keep that detail as unknown. A different flavor, shade or formulation needs its own check.

For names used in this check, read whey. For the full reading method, use our food label guide. The food allergies guide adds context for your needs.
