Final answer:
Potentially hazardous food in a vending machine must be stored at 21°C (70°F), removed from their wrapper before being put in the machine, and dispensed in their original containers or wrappers. It is not necessary to wrap the food in metal foil.
Step-by-step explanation:
When it comes to the storage and handling of potentially hazardous food in a vending machine, there are several guidelines that should be followed:
Stored at 21°C (70°F): Packaged potentially hazardous foods, such as a wrapped sandwich to be microwaved, should be stored at a temperature below 21°C (70°F) to prevent the rapid multiplication of bacteria.
Removed from their wrapper before being put in the machine: The packaged food should be removed from its wrapper before being placed in the vending machine. This is to ensure that the food can be properly heated or cooled, depending on its intended temperature.
Dispensed in their original containers or wrappers: The food should be dispensed in its original packaging, such as a box or wrapper, to maintain its integrity and prevent contamination.
Not wrapped in metal foil: There is no requirement to wrap the food in metal foil. Wrapping the food in metal foil may affect the heating or cooling process, and it is not necessary for the safe storage and handling of the food in the vending machine.
