Answer :
Final answer:
Option a. Walls must be cleaned and rinsed but do not require sanitizing since they do not come into direct contact with food, unlike stockpots, utensils, and glasses which must be sanitized to ensure a safe level of microbial load for direct consumption.
Explanation:
Among the items listed, walls must be cleaned and rinsed but NOT sanitized. Walls, unlike stockpots, utensils, and glasses, do not come into direct contact with the food being served and thus do not require the same level of microbial load reduction. For example, while glasses used to serve beverages need to be sanitized to prevent the spread of germs to consumers, walls only need to be kept clean to maintain a tidy appearance and avoid the accumulation of dirt and dust. Sanitizing, which goes beyond mere cleaning by reducing or eliminating pathogens to safe levels, is reserved for items with which food or drink comes into direct contact.
