Which of the following materials is not allowed as a floor covering in food preparation areas?

Carpet is not allowed as a floor covering in food preparation areas because it creates a challenging environment for hygiene and cleanliness. Unlike hard surface materials such as tile, ceramic, or vinyl, carpet can trap food particles and moisture, making it difficult to clean thoroughly. This can lead to the growth of bacteria and other pathogens, which pose a significant risk in food safety. In areas where food is prepared, it is essential to maintain a sanitary environment to prevent contamination, which is effectively supported by hard surface flooring materials that can be easily and regularly cleaned and sanitized.
