Final answer:
The minimal internal temperature for microwaved food to be considered safe is 165 degrees Fahrenheit, as this level is capable of killing harmful bacteria.
Step-by-step explanation:
The minimal internal temperature to which any food must be heated in a microwave to ensure it is safe to eat is 165 degrees Fahrenheit. This temperature ensures that harmful bacteria are killed, preventing foodborne illness. According to food safety guidelines, it is essential to use a thermometer to check that the food has reached this temperature. Temperature control is critical as bacteria can multiply rapidly at temperatures from 40 to 140 degrees Fahrenheit. Therefore, heating foods to at least 165 degrees Fahrenheit is necessary for food safety when microwaving.
