You may possibly have heard that microwave ovens are harmful. Actually, most people’s fears are unfounded. To this day, no relationship between microwaves and cancer or any other disorder has been confirmed. Even the late 1980s study, which actually started many of the safety concerns, wasn’t decisive. Though there are a few safe practices that you need to observe in operating present day microwave ovens, the judgment of experts is that they are generally safe.

Microwaves Do Not Cause Cancer

No-one has ever caught cancer or another illness from the use of a microwave oven. Microwaves actually produce non-ionizing radiation, the opposite of other kinds of radiation and x-rays which are linked to cancer and other conditions. Nevertheless, even if radiation is crossed off the list, there are other safety issues pertaining to the use of microwaves that we really should be aware of. Microwaving has its dangers, just like any other food preparation technique .

Heating Liquids Requires Especial Care

Warming up liquids in a microwave container with a smooth surface can result in overheating. Paradoxically, they may well rise to a temperature higher than boiling point without actually boiling. When you disturb the liquid by adding other materials or by moving the container, they can begin to boil violently. This may bring about a sudden burst of water and steam, leading to scalding and burns. This is more likely to occur with distilled water, but superheating can also occur with other liquids, such as tea and coffee.

Be Sure Containers are Vented

There can also be danger in cooking various other types of food apart from liquids. There is a chance of explosion in microwaves when using containers that aren’t suitably ventilated, or foodstuffs with a skin or shell, such as potatoes and eggs. Steam can build up inside these foods or containers, with no way out, resulting in an explosion. At some point, the pressure may cause the food to explode. This often results in a big mess and possibly burns. Products that have been warmed up for long stretches of time can also catch fire.

Never Under Any Circumstances Put Metal in a Microwave

Most people know not to put metal into a microwave oven. Metal can cause sparks or arcing electricity, because the metal in the object vibrates, producing an electric charge. You really need to be careful with takeout foods – inadvertently microwaving a box with a metal handle, or a twist tie that has a wire inside, can cause fires. To avoid the possibility of fire, be sure to remove any metal before using the microwave.

Other Things to Bear in Mind

Never turn on a microwave oven that has nothing inside it. When microwaves are turned on with nothing inside to absorb the radiation, they will form a standing wave inside. This energy will be reflected between the tube and the cooking chamber, and can easily burn out your microwave. For the same reason food that is dried out or is inside a metal wrapper should never be microwaved. The wave will be reflected, rather than absorbed, by these materials.

If foods are arranged wrongly, they may arc. Grapes are an example of this. Fire inside the microwave could also produce a spark of electricity – never put anything that’s on fire inside your microwave. All foods should be carefully handled, even when they don’t look warm. They may be warmer than they seem, and liquids can be especially hazardous. Handling your microwave with care will enable you to produce tasty, safe food. So, the bottom line is that you can prepare food with a microwave oven with the knowledge that it will present no dangers when used correctly. Just bear in mind the points mentioned in this article, as microwaves need a few special precautions, just like any other cooking method.
