Final answer:
Refrigerated food prepped on-site can be kept in a vending machine for a maximum of seven days, as long as it is stored at temperatures at or below 4 degrees C (40 degrees F).
Step-by-step explanation:
The maximum amount of time that refrigerated food that was prepped on-site can be kept in a vending machine is one day. Perishable foods should be refrigerated as soon as possible and any perishable leftovers left at a temperature between 40 and 140 degrees F for more than two hours should be thrown out to prevent the growth of bacteria.
The maximum amount of time that refrigerated food that was prepped on-site can be kept in a vending machine is seven days. The food must be stored at or below 4 degrees C (40 degrees F) to prevent bacterial growth. Keep in mind that if perishable foods are left at a temperature between 4 and 60 degrees C (40 and 140 degrees F) for more than two hours, they should be discarded as they may no longer be safe to consume.
