Which of the following is NOT a major allergen listed in common guidelines?

• A. Milk.
• B. Corn.
• C. Soy.
• D. Wheat.

Answer: (B)

Major allergens are the specific foods that regulations require to be clearly labeled and carefully managed because they commonly trigger severe reactions. In most guidelines, the eight recognized major allergens are milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, and soy. Corn isn’t included in that official list, so it isn’t treated as a major allergen in standard guidelines. That’s why corn is the correct choice here. Milk, soy, and wheat are all major allergens, which is why they fit the guidelines.
