The following foods can't be put in the microwave oven.

1. Don't heat the meat half-cooked. Because bacteria will still grow in semi-cooked food, because the time is short, it is impossible to kill all bacteria by microwave heating for the second time. Frozen meat must be thawed in the microwave oven before it is heated and cooked. ?

2. Avoid freezing the meat thawed in the microwave oven again: Because the meat has been thawed in the microwave oven, the outer layer has actually been heated at a low temperature, and bacteria can reproduce at this temperature. Although freezing can prevent its reproduction, it can't kill the living bacteria. If the meat thawed in the microwave oven is frozen in the refrigerator again, it must be heated until it is fully cooked.

3, avoid fried food: because high-temperature oil will splash and cause fire. In case of accidental fire in the furnace, don't open the door, turn off the power first, and then open the door to cool down after the fire is extinguished.
