In food prep and warewashing areas, what should floors, walls, and ceilings be made of?

Giải thích

In areas subject to moisture and food debris, floors, walls, and ceilings must be built of smooth, durable, nonabsorbent, and easily cleanable materials so they can be kept clean and do not harbor moisture or pests. Carpet soaks up spills, unsealed wood absorbs moisture through its grain, and cracked concrete holds debris where it cannot be reached — none of the three can be sanitized. Correct construction materials are a first-line defense against contamination and pests.
