What is the main purpose of changing gloves during sandwich preparation?

The main purpose of changing gloves during sandwich preparation is to prevent cross-contamination. This practice is crucial in maintaining food safety standards and ensuring that different types of food do not come into contact with each other, which could lead to allergic reactions or the spread of harmful bacteria. For instance, if a worker uses the same gloves after handling raw meat and then prepares vegetables for a sandwich, there is a risk of transferring harmful pathogens to the vegetables. Keeping gloves clean and changing them between tasks helps to protect customer health and uphold hygiene protocols in food preparation environments. This practice is a key component of food safety training and is emphasized to prevent foodborne illnesses, ensuring a safe eating experience for customers.
