Which surfaces must be both cleaned and sanitized? Cutting boards Garbage containers Storage shelves Walls

The correct answer is:<br /><br />**Cutting boards**<br /><br />### Explanation:<br />Cutting boards come into direct contact with food, making them a critical surface for both cleaning and sanitizing. Cleaning removes visible dirt and debris, while sanitizing reduces harmful bacteria to safe levels. This dual process helps prevent cross-contamination and ensures food safety.<br /><br />Other surfaces like garbage containers, storage shelves, and walls may only require cleaning unless they are in direct contact with food or pose a contamination risk.
