Microwave oven usage taboo: what foods can't be heated in the microwave oven
Nine taboos of microwave oven:
1. Do not heat the meat until it is half cooked and then heat it in a microwave oven:

2. Avoid refreezing meat thawed in microwave oven:
Because after the meat is thawed in the microwave oven, the outer layer has actually been heated at a low temperature. At this temperature, bacteria can reproduce. Although re freezing can stop their reproduction, it can not kill the living bacteria. Meat that has been thawed in the microwave oven must be heated until fully cooked if it is frozen in the refrigerator.
3. Avoid fried food:
High temperature oil will splash and cause fire. In case of fire in the furnace caused by carelessness, do not open the door, but turn off the power supply first, and then open the door to cool down after the fire is extinguished.
