How Long Is Pizza Good for Left Out?
Pizza that has been left out overnight is not safe to eat.
Leaving pizza out can cause bacteria to grow and can lead to foodborne illnesses.
Bacteria grow on food in the “Danger Zone” between 40°F and 140°F, so perishable foods like pizza should be kept at 40°F or below.
If pizza has been at room temperature or in the danger zone for more than two hours, it should not be consumed.
Perishable food should not sit out for more than an hour if the temperature is above 90°F.
Bacteria on leftover pizza can double in number in as little as 20 minutes, increasing the risk of exposure to foodborne pathogens.
Therefore, if pizza has been left out overnight, it is recommended to throw it away to avoid the risk of foodborne illness.
Quick Tips and Facts:
1. Contrary to popular belief, pizza left out at room temperature should not be consumed after two hours. Bacteria can multiply rapidly on pizza, especially if it contains perishable toppings like meat or dairy.
2. It is generally recommended to refrigerate leftover pizza within two hours of it being served. While refrigeration slows down bacterial growth, it does not completely eliminate it. Therefore, it is advisable to consume refrigerated pizza within three to four days.
3. Freezing is an effective way to extend the lifespan of leftover pizza. When properly stored in an airtight container or freezer bag, pizza can last in the freezer for up to two months without significant quality loss.
4. It is important to keep in mind that the texture and taste of leftover pizza may change slightly after being refrigerated or frozen. The crust may become softer, and the toppings may not retain their original freshness and crunch.
5. Reheating pizza in the oven or on a stovetop pan is generally preferred over using a microwave. This method helps to rejuvenate the crust’s crispiness and maintain a more even distribution of heat throughout the slice.
Safety Risks Of Eating Leftover Pizza
According to food safety experts from the USDA and the Cleveland Clinic, consuming leftover pizza that has been left out overnight is not safe. Pizza is classified as a perishable food and can spoil rapidly if not stored correctly. Leaving pizza at room temperature creates an ideal environment for bacteria to thrive and can significantly raise the chances of developing foodborne illnesses like Staphylococcus aureus, E. coli, and Campylobacter.
Bacteria Growth On Pizza Left At Room Temperature
To understand the dangers of eating pizza that has been left out overnight, it is essential to comprehend how bacteria grow on perishable foods.
Bacteria thrive in environments between 40°F and 140°F, known as the “Danger Zone.” When pizza is left at room temperature, it quickly reaches or exceeds this temperature range, providing an ideal habitat for bacteria to multiply. The longer pizza remains in the danger zone, the greater the chances of harmful bacteria contaminating the food.
It is for this reason that perishable foods, including pizza, should always be kept at 40°F or below.
- Bacteria grow on perishable foods in the temperature range between 40°F and 140°F, known as the “Danger Zone”.
- Room temperature allows pizza to quickly reach or exceed the Danger Zone, providing a favorable environment for bacterial growth.
- The longer pizza stays in the Danger Zone, the higher the risk of harmful bacteria contaminating the food.
- Perishable foods, such as pizza, should always be stored at or below 40°F.
Keeping perishable foods, like pizza, at or below 40°F is crucial to prevent harmful bacterial contamination.
Time Limits For Leaving Pizza In The “Danger Zone”
According to food safety guidelines, pizza that has been left in the danger zone for more than two hours should not be consumed. However, it is important to note that the time limit may vary depending on certain factors, such as the ambient temperature. In warmer climates or if the temperature is above 90°F, perishable foods should not sit out for more than an hour.
This is because bacteria on leftover pizza can double in number in as little as 20 minutes, significantly increasing the risk of exposure to foodborne pathogens.

- Bacteria on leftover pizza can double in number in 20 minutes, increasing the risk of foodborne pathogens.
Increased Bacterial Numbers On Leftover Pizza
The growth of bacteria on leftover pizza is a significant concern due to the rapid increase in bacterial numbers. When pizza sits out at room temperature, any bacteria present on the food start to multiply. In just a short period, the number of bacteria can double or even triple, leading to a higher concentration of harmful microorganisms. Consuming pizza with this increased bacteria load can greatly heighten the risk of developing foodborne illnesses. Therefore, it is crucial to exercise caution when considering eating leftover pizza that has been improperly stored.
- Leftover pizza can experience a rapid growth in bacterial numbers when left at room temperature.
- Improperly stored pizza can have a higher concentration of harmful microorganisms.
- Consuming such pizza greatly heightens the risk of developing foodborne illnesses.
Note: Always store leftover pizza properly to avoid bacterial growth.
Symptoms And Risks Of Foodborne Illness
Consuming pizza that has been left out overnight can increase the risk of foodborne illnesses. These illnesses can cause various symptoms, including cramping, stomach pain, diarrhea, nausea, vomiting, and fever. Most of the time, these symptoms are mild and typically go away within a few days. However, it’s important to note that severe cases may require medical attention. If symptoms persist for more than 24 hours, individuals, especially those at higher risk, such as children, pregnant women, older adults, and those with weakened immune systems, should seek immediate medical attention if they suspect food poisoning.
Proper Storage And Reheating Of Leftover Pizza
To minimize the risk of foodborne illnesses, it is essential to store leftover pizza properly. Here are some guidelines to follow:
Store pizza in an airtight container or wrap it tightly in aluminum foil or plastic wrap before placing it in the refrigerator. This prevents bacteria from contaminating the food and slows down their growth.
Leftover pizza can be safely stored in the refrigerator for three to four days, and it is recommended to consume it within this time frame.
Alternatively, pizza can be frozen. While it remains safe indefinitely, it is optimal to consume it within three months for the best taste.
When reheating leftover pizza, it is important to ensure food safety by reaching the appropriate internal temperature. Aim for an internal temperature of 165°F to eliminate any remaining bacteria and reduce the risk of foodborne illness.
Note: If pizza has been left out overnight, it is strongly recommended to discard it instead of trying to salvage it. The potential for bacterial contamination is significant, and the health risks associated with eating such pizza outweigh the convenience of saving a few slices. Always prioritize food safety and opt for freshly made or properly stored pizza instead.
