Can microwave kill if used for heating food always?

Microwave ovens are designed to heat food by agitating water molecules, which generates heat. While they are generally safe when used properly, there are risks associated with improper use, such as overheating liquids that can lead to burns or explosions. Additionally, microwaves do not kill bacteria or pathogens effectively if food is not heated to the appropriate temperature. Therefore, while they are safe for heating food, caution is necessary to prevent accidents or foodborne illness.
