Which of these foods contains a Big 9 allergen that may be hidden and surprise an allergic guest?
a.A whole apple (rinsed and sliced)
b.Plain white rice (steamed in water)
c.Bottled spring water (sealed bottle)
d.Soy sauce (contains wheat and soybeans)
Explanation
Brewed soy sauce is made from both wheat and soybeans, two of the Big 9 allergens, and guests rarely expect the wheat, so it is a classic hidden source in marinades, dressings, stir-fries, and dipping sauces. Managers and servers must know the hidden allergens in every sauce on the menu. A rinsed and sliced apple, plain white rice steamed in water, and sealed bottled spring water contain none of the Big 9, which is why they are safe answers to give a guest.
