For how long should microwaved foods be cooked at the proper temperature?

When heating food in a microwave, it is vital to ensure that it reaches a safe internal temperature to eliminate any harmful bacteria that can lead to foodborne illness. The guideline of cooking for 15 seconds at the proper temperature usually pertains to reheating or bringing food to a safe temperature, which in many cases means reaching at least 165°F (74°C).

This brief burst of reheating is especially relevant when dealing with ready-to-eat foods or leftovers that have been refrigerated and need to be heated quickly to a safe temperature. Cooking for this duration helps ensure that the food is adequately heated without overcooking or drying it out.

In practical terms, 10 seconds may not be sufficient for most foods, and durations longer than 15 seconds, such as 30 seconds or 1 minute, often exceed what might be necessary to achieve the proper temperature while keeping the food palatable. Thus, the correct answer emphasizes achieving safety while considering quality.
