Besides being convenient and effective, microwave ovens can be considered green because they operate much faster than a conventional oven and use much less energy. Generally, microwaves are great for reheating food or for food that cooks quickly. Trying to prepare a large dish solely by nuking it may not result in the best taste. For times when you do choose to use the microwave, however, make sure you’re not achieving eco-benefits at the expense of your health. The following are tips for safe microwave operation.
Keep a Safe Distance – Food in a microwave oven is cooked by passing microwave radiation through it, causing water molecules within the food to vibrate faster, thus causing friction that heats the food. New technology in door seal design effectively eliminates the danger of leaking radiation. Old, or faulty door seals, as well as a buildup of dirt could cause a small amount of radiation exposure. In theory, there could be small amounts of leakage through the viewing glass, but studies measuring this have found levels to be insignificant. Microwave radiation strength decreases rapidly with increasing distance from the microwave itself. So, the farther from the microwave you stand the less radiation you will be exposed to. At one meter away, the radiation level is nil.
Proper Cookware – Using plastic containers in the microwave, even if they say microwave safe, may not be the best way to go. Plastics can leach harmful chemicals when hot. Never use plastic margarine tubs or the like, or take-out cartons or plastic wrap in the microwave. Use glass or ceramic dishes that are labeled microwave safe. Never use aluminum foil or any form of metal in the microwave.
Avoid Foodborne Illness – If cooking meat or similar foods, make sure that a high enough temperature has been reached to kill harmful bacteria. Microwave ovens can cook unevenly, thus leaving ‘cold spots’ where bacteria can survive. Keep the oven clean to avoid a buildup of bacteria.
Cover Up – Cover food, but allow for steam to escape, when cooking to keep the microwave clean, for more uniform cooking, and to prevent particles of food from damaging exposed areas of the microwave and making it less efficient.
Don’t Get Burned – While the container you’ve used in the microwave may not be hot to the touch, be careful you don’t get burned by the contents, which can be very hot.
