Which of the following surfaces can typically just be cleaned and rinsed?

The correct answer indicates that walls can typically just be cleaned and rinsed. This is because walls in food preparation areas generally do not come into direct contact with food, as cutting boards and cooking utensils do. The primary purpose of cleaning and rinsing walls is to remove dust, grease, and other residues that could encourage pest infestation or provide a breeding ground for bacteria. Since walls are not surfaces that require sanitization in the same way that food contact surfaces do, a simple cleaning and rinsing is usually sufficient to maintain their cleanliness.

In contrast, cutting boards and cooking utensils are surfaces that come into direct contact with food and therefore require more than just cleaning and rinsing. They must be scrubbed thoroughly and sanitized to ensure that any harmful bacteria or contaminants are eliminated. Countertops, like cutting boards and utensils, are also food contact surfaces that must be cleaned and sanitized properly to prevent cross-contamination.
