What is the purpose of segregating allergenic foods during preparation?

The purpose of segregating allergenic foods during preparation is primarily to prevent cross-contact with non-allergenic foods. Cross-contact occurs when allergenic ingredients come into contact with foods that do not contain those allergens, potentially leading to an allergic reaction in sensitive individuals. By keeping allergenic foods separate from others, food handlers can significantly reduce the risk of unintended exposure to allergens, ensuring the safety of customers who have food allergies. This practice is crucial in maintaining food safety standards and protects those who are at risk of serious health reactions due to allergies.
