How accurate is the allergy checker?

The checker matches ingredient text against our allergen database and your saved profile. It works best with complete ingredient lists. Always verify with the original product label and consult a medical professional for severe allergies.

Can the allergy checker detect cross-contamination risks?

The checker can flag 'may contain' and 'shared facility' warnings when that information is included in the ingredient text. Cross-contamination risk that isn't disclosed in the label cannot be detected.
