Milk is the common allergen in yogurt because yogurt is made from milk. Milk contains proteins that can trigger allergic reactions in people with a milk allergy, so the allergen is present in the product regardless of flavor or added ingredients. The other options—eggs, wheat, and tree nuts—are not ingredients typically found in standard yogurt. Remember, in a kitchen or facility that handles multiple allergens, cross-contact is a separate risk to manage, but the direct allergen in yogurt itself is milk.
