What is the minimum internal temperature for microwave foods?

• A. 165 degrees F
• B. 150 degrees F
• C. 160 degrees F
• D. 170 degrees F

Answer: (A)

Microwave reheating must bring the food to a safe internal temperature throughout to kill any harmful bacteria that could survive uneven heating. The minimum safe temperature for reheating is 165°F (74°C). Reaching this temperature in every part of the food ensures that all portions are heated enough, even if some areas heat more slowly in a microwave. To apply this, use a food thermometer to check the center and other spots, and stir or rotate the food as needed so every part reaches 165°F or higher. The other temperatures aren’t sufficient to guarantee safety in all cases—150°F and 160°F are below the required threshold, and 170°F, while safe, isn’t the minimum necessary and can affect texture without added safety benefit.
