Question

which of the following is an example of proper food storage?
bags of dried rice are stored on a shelf in a dry area of the storeroom
bags of red beans are stored on the floor in a dry area of the storeroom
bags of flour are stored on wooden pallets beneath a storeroom sewer pipe that shows no sign of damage
open bags of cornmeal are stored on storeroom shelves

Explanation:

Proper food storage involves keeping items dry, off the floor (to prevent moisture and pest access), and away from potential contaminants like damaged pipes. Storing bags of dried rice on a shelf in a dry area meets these criteria. Storing on the floor (as with red beans) is bad. Beneath a sewer pipe (cornmeal) risks contamination. Wooden pallets (flour) might not be as hygienic as shelves for dry - storage in some cases (though pallets are better than floor, shelves are often preferred for dry goods like flour for easier cleaning and less risk of moisture wicking).

Answer:

Bags of dried rice are stored on a shelf in a dry area of the storeroom.
