Most burns associated with microwave ovens are preventable. Be careful when removing lids from micro waved foods. Puncture plastic wrap before heating foods in the microwave. Remember that the fillings in foods may become very hot, even though the outer portion remains only warm to the touch. Stir foods to distribute the heat.
Many microwave ovens heat from the outside edge toward the middle.
This can produce very hot food on the edge and cold food in the middle. Extreme caution should be exercised when heating baby bottles or baby food. Heating baby formula in a microwave is a dangerous practice and could result in a scald to the baby's mouth or throat. Even though a bottle might not feel warm, there may be hot spots within the formula. Hot spots are places where the microwaves have reached first or more efficiently, producing uneven heating.
