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.
