Which of the following is NOT a common allergen?

Tomatoes are not classified as one of the common allergens. The list of common allergens typically includes foods that are most frequently associated with allergic reactions, and these are often referred to as the "Big Eight," which include peanuts, tree nuts, milk, eggs, fish, shellfish, soy, and wheat.

Peanuts and shellfish are well-known for causing severe allergic reactions in susceptible individuals, while wheat is also on the list due to gluten allergies, such as celiac disease. Tomatoes, on the other hand, while they can cause reactions in some individuals, are not among the top allergens recognized in food safety regulations and guidelines.

This understanding is crucial in food service and safety to ensure that individuals with food allergies are protected and informed about what foods may trigger their allergies.
