Disadvantages

 Even though microwaves have advantages, it is important to know that they also have some disadvantages: 

• The radiation can be harmful in case someone is really close to the window.
• It can be harmful in case the food is overheated or under heated. 
• It can cause food poising as it doesn't kill bacteria. 
• When plastic is microwaved, dangerous chemicals like BPA and phthalates can leak into your food and beverages. Therefore, unless it is specifically labelled for this usage, you should avoid microwaving plastic.
• It's crucial to use caution when heating liquids because overheated liquids have a slim chance of bursting out of their containers and burning the person.
• Due to the possibility of scald burns, never reheat baby formula or any other food or drink marketed for young children in a microwave.
