Can you leave plates of food to be eaten later on-top a microwave if the is used in mean time will it not keep reheating on top microwave?

No, it is not safe to leave plates of food on top of a microwave if the microwave is being used. Even though microwaves are designed to heat food from the inside out, they can still generate enough heat to cause the food on top of the microwave to become warm or even hot. This can pose a food safety risk, as bacteria can grow rapidly in warm or hot environments. Additionally, the heat from the microwave can cause the food to dry out or become tough.

It is best to store plates of food in a safe place, such as the refrigerator or a food storage container, when they are not being eaten. This will help to keep the food fresh and safe to eat.
