FAQs: Using Plastics in the Microwave

Is It Ever Safe to Use Plastic in the Microwave?

Plastics intended for food storage or preparation are analyzed by the Food and Drug Administration (FDA) before they ever hit the market. If the product is intended for use in the microwave, it must undergo additional testing. Those deemed microwave safe have been seen to withstand microwave heating without warping, melting, or other damage.

How Do I Know Which Products Are Microwave Safe?

Check item packaging for care and use instructions. Those deemed safe for microwave use will be clearly marked as such. If packaging is no longer available, check the item itself. 

If you can't find a "microwave safe" label or symbol on the product or its packaging, it is advisable to opt against using that product in the microwave. Unmarked items are not necessarily unsafe; it simply means that the product was not tested or approved for microwave use.

I've heard that microwaving plastic releases toxic chemicals. Is it true?

A group of chemicals known as dioxins are usually the culprit in such claims. However, most plastics lack the chemical compounds needed to form dioxins. Also, these chemicals typically form at temperatures over 700 degrees Fahrenheit - much hotter than the inside of your kitchen microwave. The FDA states: "With regard to dioxins, we have seen no evidence that plastic containers or films contain dioxins and know of no reason why they would."
