Lifting the cup from the microwave with your bare hands can result in burns.
BPA and Plastic CupsBPA is a material that is commonly used in the manufacture of plastic serving kitchenware. They are used for the manufacture of most items that are used in the kitchen, feeding bottle, plastic cups, plastic plates e.t.c.It is usually added to these utensils to harden them as well as line cans and medical equipment. A person will usually get exposed to BPA and its accompanying risks when they use these BPA based containers in extreme heat. The heat activates the poison in the BPA causing it to leech harmful chemicals into the cup or food.Unfortunately, this means that most of these utensils are not safe for use in your microwave. In addition, over the years, the presence of BPA in kitchenware has been discovered to cause a lot of harm to the body including heart and reproduction issues.Ingesting BPA in your diet once doesn’t necessarily expose you to harm. Usually, you will pass any BPA out as liquid waste when consumed. On the other hand, continuous exposure to BPA is very dangerous to the health.
