Every share is counted over the packs whose ingredient list Open Food Facts reads in full. A pack lists an allergen when Open Food Facts’ allergen field names it, or when one of its ingredients stands for it by the same two-of-three checks as the ingredient dictionary (tahini is sesame, a cheese is milk). A “may contain” line counts only for an allergen the pack does not list.
