Myth: Microwaving plastic containers and wraps release harmful, cancer-causing substances into food.

Fact: Microwave-safe plastic containers and wraps are safe to use in the microwave.

But plastic containers not intended for use in the microwave could melt and potentially leak chemicals into your food. So avoid microwaving containers that were never intended for the microwave, such as margarine tubs, takeout containers or whipped topping bowls.

You should always check to see that any container you use in the microwave is labeled as microwave-safe.
