Typically, the cooking process requires low temperatures to thaw food, and longer temperatures to cook it. However, some foods cannot be cooked from frozen and must be completely thawed before use.
What happens when you heat up frozen food?
During thawing, the microwave oven raises the temperature of the food, entering the danger zone of 40 to 140 degrees Fahrenheit, where bacteria begin to grow and multiply. Remember, frozen foods contain bacteria, even though they are inert. As the temperature of the food rises, the bacteria re-activate.
