Can a microwave kill germs like flu viruses, coronaviruses, and harmful bacteria? The short answer is yes, but not evenly and maybe not in the way you think. Unfortunately, there's no standard set of guidelines for exactly how to kill the different types of germs you might be concerned about on foods, does microwave kill germs, medical devices, and other objects.

Microwave ovens produce radio-frequency waves that cause the water molecules in an object to vibrate. This vibration causes friction, which allows the object to heat up to a temperature that can kill germs. That's why microwaves are sometimes used to disinfect items such as a household sponge, as they are a hotbed for viruses and bacteria. However, research has found mixed results on whether a microwave can effectively kill germs on a sponge, or even in food. Here's what you need to know.

For many households, using a microwave for making popcorn in minutes with little mess, heating leftovers, and keeping the coffee steaming are part of everyday life. What is less likely thought about it how food must be heated to a safe internal temperature to kill bacteria and any potential pathogens to achieve food safety with all cooking methods, including microwaved foods. Because microwave ovens may cook unevenly and leave cold spots, harmful food-borne-illness-causing pathogens may survive. The USDA has recommended temperatures to ensure food safety when microwave cooking. For those of us in the food industry, microwave food has compelling benefits and challenges. Moreover, newer microwave technologies create intriguing opportunities to promote food safety, such as exploring microwave-assisted drying methods Zielinska et. When food is heated in a microwave, the water content in the food is heated, which in turn cooks the food ingredients. Microwaves produce very low-energy electromagnetic radiation, and these waves do not have enough energy to break chemical bonds. Instead, the electromagnetic waves excite electrons in water molecules, causing them to vibrate. According to the Food and Drug Administration FDA , microwaves cause water molecules in the food to vibrate, producing heat that cooks the food. The FDA describes radiation of visible light, radiofrequency, and microwaves as being on the spectrum of non-ionizing electromagnetic radiation. Ionizing radiation such as x-ray or ultra-violet light can damage cells and alter atoms and molecules.

According to one study observing the effect of short-time microwave exposures on Listeria does microwave kill germsmicrowaving proved to be a cost-effective, practical, and safe method of decontaminating foods. In fact, it is not only the temperature, which is important in eliminating the presence of pathogens and infections in the food, but the fact that heating in a microwave does not disinfect evenly and can leave behind pathogens.

Most foods should be microwaved to a temperature of degrees Fahrenheit to kill bacteria. This article answers whether a microwave can kill bacteria, among other topics like How do microwaves work, Can bacteria survive in microwave? How long a microwave takes to kill bacteria, among others. A microwave contains magnetrons that create wave energy which vibrates water molecules in the food to produce heat. Microwaves consist of magnetrons responsible for the creation of radio wave energy.

However, non-ionizing microwaves are low-energy electromagnetic radiation that does not break elemental bonds. Currently, there is no evidence showing that eating microwaved food has any detrimental effects on humans or animals. However, chemical and physical changes occur in foods at high heat. There's no doubt that heat can help destroy some germs like bacteria and viruses. This is how Shilpa Shetty lost 32kgs: Simple tips to follow. The short answer is yes, but not evenly and maybe not in the way you think. Microwaves Kill With Heat, Not Actual Microwave Radiation Over time, researchers have learned that it is the heat, not the actual microwaves, that can disinfect an item. Items should air dry completely before they are reused or put into storage. The CDC warns that microwaving your toothbrush could actually damage it. While cooking food conventionally by baking or frying as well as microwaving, bacteria and viruses in foods are destroyed.
