Trays which overhang shelving
- A.
Can become contaminated.
- B.
Are ok for rigid containers, but not for flat wrapped trays.
- C.
Is the appropriate way to store trays as it allows for the use of proper body mechanics when lifting heavy trays.
- D.
None of the above.
Correct Answer
A. Can become contaminated.Explanation
The correct answer is "can become contaminated." This is because when trays overhang shelving, there is a risk of them coming into contact with dirt, dust, or other contaminants, which can contaminate the food or items placed on the trays. It is important to ensure that trays are properly stored and protected to maintain hygiene and prevent contamination.Rate this question:
