Is your microwave a ticking time bomb? 10 things to avoid

The microwave is a modern marvel that has revolutionised cooking, making it faster and more convenient than ever before. However, not everything is suitable and some items can pose serious risks to your health and safety.

In this article, we’ll explore ten things you should never put in the microwave to keep yourself and your loved ones safe.

Chili Peppers: A Microwave Hazard

Chili peppers contain capsaicin, a compound that gives them their signature kick. When heated in the microwave, capsaicin vaporises into the enclosed air, releasing fumes that can irritate and burn your lungs, throat, eyes, and nose. To avoid this, roast, sauté, or grill peppers instead.

Hard-Boiled Eggs: A Potential Explosion

Heating hard-boiled eggs in the microwave, whether in the shell or peeled, can cause them to explode due to the buildup of steam inside the egg. When you cut or bite into the egg, the steam is released instantly, potentially causing burns.

To safely heat hard-boiled eggs, slice them into fourths before microwaving or let them sit in a cup of hot water for 3 to 5 minutes.

Styrofoam: A Chemical Concern

Food-safe foam, a type of plastic, can release harmful chemicals into your food and the air when heated in the microwave. Styrofoam is also not heat-stable and may melt or warp when exposed to microwaves.

Always transfer food to a glass plate or safe container before heating.

Takeout Containers With Handles: A Fire Risk

Takeout containers with metal handles can spark and cause a fire in the microwave.

To avoid this, empty leftovers onto a microwave-safe container or plate, cover with a paper towel, and heat normally.

Mug of Water: A Superheating Danger

Heating water by itself in the microwave can lead to superheating, where the water becomes extremely hot without showing signs of boiling.

When disturbed, the water can suddenly erupt, causing burns. To avoid this, use a kettle to heat water safely.

Grapes: A Plasma Hazard

Grapes can become superheated in the microwave, with their sugary pulp turning into molten plasma. They may explode in the microwave or when you take a bite, sending ultra-hot fruit flying.

If you want to heat grapes, consider roasting them in the oven or sautéing them in a skillet.

Leftover Potatoes: A Botulism Risk

Potatoes can house Clostridium botulinum, the botulism bacteria. If cooked potatoes are not immediately stored in the fridge, spores of the bacteria can multiply.

Microwaving won’t kill the bacteria, so reheated potatoes could cause an upset stomach. Move cooked potatoes to the fridge quickly and reheat them in the oven for safety.

Processed Meats: A Health Concern

Heating processed meats like bacon, hot dogs, lunch meat, and sausages in the microwave can lead to the formation of cholesterol oxidation products (COPs), which have been linked to coronary heart disease, inflammation, and plaque buildup in the arteries.

Baking or sautéing these meats may be safer options.

Tomato Sauce: A Splattering Mess

Heating tomato sauces in the microwave often results in splatters due to the buildup of steam that struggles to escape through the thick sauce. This can lead to burns and stained clothes.

To avoid this, heat sauces in a small pan on the stove, allowing for even heating and easy stirring.

An Empty Microwave: A Fire Hazard

Never start an empty microwave oven. Without food or a container to absorb the microwaves, the beams are bounced back to the magnetron, potentially damaging the machine and even starting a fire.

Always double-check that you’ve put food in the microwave before pressing start.

By being aware of these dangers and following the proper heating methods, you can ensure that your microwave remains a safe and convenient tool in your kitchen.
