What should be done with leftover pizza?

Leftover pizza should be cooled rapidly and refrigerated within 2 hours to ensure food safety. This practice is essential to minimize the risk of bacterial growth that can occur when food is left at room temperature for an extended period. The temperature danger zone, defined as between 40°F and 140°F, is where harmful bacteria can multiply rapidly. To safely store leftover pizza, it should be placed in the refrigerator as soon as possible after it has cooled down to avoid lingering in the danger zone.

Refrigeration slows down the growth of bacteria, thus preserving the food quality and safety for future consumption. Additionally, reheating the pizza properly before serving can further ensure that any potential pathogens are killed, making it safe to eat again. This method reflects best practices in food handling by prioritizing safety and reducing food waste.
