Final answer:
Tableware and utensils should be stored 6 inches off the floor to maintain sanitation and prevent contamination.
Step-by-step explanation:
In order to maintain proper sanitation and prevent contamination, tableware and utensils should be stored a minimum of 6 inches off the floor.
This is to ensure that they are not in contact with any dirt, dust, or other potential sources of contamination that may be present on the floor.
By storing tableware and utensils at this height, it helps to maintain cleanliness and reduce the risk of bacterial growth or cross-contamination.
