Why Health Experts Never Use Plastic In The Microwave

Could using plastics in the microwave be dangerous to your health? The answer is “yes,” according to important news from John Hopkins Bloomberg School of Public Health.

There have been many stories circulating about the safety of microwaves, heating, plastics and food. Some have focused on dioxin, a known carcinogen. Dioxin occurs in our environment, primarily from the incineration of waste materials, according to Dr. Rolf Halden, at John Hopkins Bloomberg School. People are exposed to dioxin mostly from eating meat and fish rich in fat. But it may not be the sole offender.

There are other concerns we should consider, according to Halden. There’s a group of chemicals called “phthalates” that have been added to some plastics to make them flexible and less brittle. If you heat these plastics, it can increase the leaching of phthalates from the containers into your food.

Many scientific studies have shown that when you heat up an object, the chemicals are more likely to release into the environment. This is the same with plastics...and possibly the plastic packaging in some microwave meals.

Another chemical, diethylhexyl adipate (DEHA), is also used to make plastics more flexible. DEHA exposure can occur when eating certain foods wrapped in plastics. “It’s true that substances used to make plastics can leach into food,” says Edward Machuga, Ph.D., a consumer safety officer in the FDA’s Center for Food Safety and Applied Nutrition. “But the levels are low.”

What should you do? People should use heat resistant glass, Corning Ware or ceramic containers for heating food in the microwave. Don’t use foam or plastic carryout containers from restaurants or margarine tubs in the microwave, according to the FDA. And never use plastic storage bags, grocery bags, newspapers or aluminum foil in the microwave.
