What is not allowed regarding the cleanliness of the establishment's areas?

Neglecting sanitation procedures is not allowed as it directly compromises the health and safety of both staff and patrons in an establishment. Maintaining cleanliness is crucial, especially in environments where food is prepared and served, or where public health is a concern. Regular cleaning and proper sanitation are mandated to prevent the spread of germs and contamination.

Regular cleaning of surfaces ensures that harmful bacteria and viruses are minimized. Using single-use items also plays a vital role in maintaining hygiene, as these items help reduce the risk of cross-contamination. Frequent handwashing is critical in keeping both workers and customers safe from potential infections and maintaining overall cleanliness within the establishment.

Therefore, neglecting sanitation procedures undermines all these important practices and poses a significant risk, validating why this option is the correct choice.
