What is a major food allergen?

A major food allergen is a food substance that can trigger allergic reactions in susceptible individuals. The eight primary allergens recognized in many countries include milk, eggs, peanuts, tree nuts, fish, shellfish, soy, and wheat. These allergens can cause symptoms ranging from mild discomfort to severe anaphylaxis. Due to their prevalence, food labeling laws often require clear identification of these allergens in food products.
