Which does not require sanitizing? Knives Plates Walls Tongs

Walls do not typically require sanitizing in the same way that knives, plates, and tongs do. In a kitchen or food preparation environment, utensils and dishes that come into direct contact with food need to be sanitized to prevent contamination and ensure food safety. Walls, while they should be kept clean, do not usually come into direct contact with food and therefore do not require the same level of sanitization.
