We all know leftovers are handy and save time. What could be easier than grabbing that plastic bowl from the fridge and tossing it in the microwave to heat up? In 30 seconds you’ve got hot food and minimal clean up. It sounds simple. But is it safe?
The questions about safety are regarding substances found in plastics such as diethylhexyl adipate (DEHA), and dioxins. DEHA is what makes plastic flexible, and dioxin is a substance found naturally in water, animal fats and soil and is known to cause cancer. The theory is that when plastic is heated in the microwave the heat actually leaches these substances into your food.
According to the FDA, any substances used to make plastics that touch food are classified as “food contact substances” and must be found safe before they can even be put on the market. While they do agree that the substances in plastics can leach into food, the levels of DEHA that might be consumed are well below any levels that warrant concern and were found to be safe in animal studies. The FDA carefully reviews how much leaching takes place and ensures that it stays within safe levels. As for dioxins, the FDA says there really is no evidence that plastic containers and plastic wrap would contain dioxins at all.
To put your mind at ease, there are a few simple rules to follow for safe microwaving.
- Only use plastic containers that are labeled as microwave-safe.
- Never use used sour cream containers, margarine tubs, or takeout containers to heat your food in.
- If something is not labeled as microwave-safe, don’t assume it is.
- If you are using cling-film, such as Saran Wrap, make sure it is labeled as micro-wave safe and do not let it touch your food in the microwave.
Be safe - and bon appetit!
