What is the minimum safe internal temperature for reheated leftovers?

• A. 135°F (57°C).
• B. 145°F (63°C).
• C. 180°F (82°C).
• D. 165°F (74°C).

Answer: (D)

Reheating leftovers safely means heating every part of the dish to a high enough temperature to kill any bacteria that could have grown while the food was cooling. The minimum safe internal temperature for reheated leftovers is 165°F (74°C). Reaching this temperature ensures that common foodborne pathogens, including Salmonella and Campylobacter, are destroyed, and holding the food at that temperature or above for a short time (about 15 seconds) helps ensure the heat penetrates to all portions.

The other temperatures don’t serve the same safety purpose: 135°F is a hot-holding temperature used when keeping food warm for serving, not for reheating; 145°F is a cooking guideline for certain raw meats and does not address reheating leftovers; 180°F is higher than necessary for safety and can degrade quality without adding safety benefits.
