Risks of Microwaving Plastics

The original information states that you risk your health if you microwave food in plastic containers. Dioxins are chemicals that are produced from several materials when subjected to heat. These materials include plastic, metal, wood, and more. Therefore, if you do not microwave your food in plastic, you do not risk contamination by dioxins. 

Plastics are created using a number of organic and inorganic compounds. The substances added are often to help alter the shape or stabilize the plastic. Two substances often added to plastics include:

  • Bisphenol-A – Also known as BPA. This substance is added to make hard and clear plastic material. 
  • Phthalates – This substance works differently because it makes plastic soft and flexible. 

When these two substances find their way in the tissues of a being, they tend to replicate the hormones, which is not a good thing. 

Once you wrap food in a plastic that contains either of the substances above and microwaves it, there are high chances of BPA and Phthalates leaking into the food. 

Risks are that BPA can affect the endocrine system, as well as the brain, especially in children.

Once the FDA recognized the potential for these chemicals to leak in food, they put up regulations that required companies to test their plastic containers before moving them to the market. They use tests used to provide FDA with information to help determine if the products can be allowed into the market. 

FDA tests will several aspects. For instance, there are tests that will determine the migration of certain substances and chemical elements at certain temperatures. For a plastic to be approved for microwave use, the FDA will determine how long the plastic might be in the microwave, the likelihood for a person to eat directly from the plastic, and the temperatures that the food might reach when heated in the microwave.

In addition, the FDA determines the elements that might migrate into food and the speed at which they do the same. Tests in labs, using lab animals, will help determine the allowable amount. If the amount is 100 to 1000 times less than the amount that can harm a lab animal, the plastic passes the test and is allowed into the market. 

An approved plastic should have a notification that it is microwave safe. 


The hardening element shifted from the known Bisphenol A to Bisphenol B. 

It is important to note that glass and ceramic containers are much safer than plastic containers. It is advisable to refrain from using plastic containers in heating your food.
