Is it Safe to Eat 5-Day-Old Refrigerated Pizza?

It is generally safe to eat 5-day-old refrigerated pizza, as long as it has been stored properly. Pizza stored in the refrigerator should be kept at 40 °F or lower to slow down the growth of bacteria. It is important to check for any signs of spoilage, such as a sour smell or off-color appearance, before consuming the pizza.

To ensure safety, reheat the pizza to an internal temperature of 165 °F before eating. However, it is always best to use your own judgment and discard it if any doubts arise about its safety.

How to Properly Store Pizza in the Refrigerator 

To properly store pizza in the refrigerator, it’s indispensable to make sure it’s stored in an airtight container or wrapped tightly in plastic wrap to prevent it from drying out. Place the pizza in the refrigerator as soon as possible after it has cooled down to room temperature.

It’s best to store the pizza on a plate or in a shallow container to catch any potential drips from the toppings. When stacking multiple slices, it’s a good idea to separate them with parchment paper to prevent sticking.

It’s recommended to consume the leftover pizza within 3–4 days for the best quality, as the toppings and crust can start to deteriorate over time. If you have a large pizza, consider cutting it into smaller slices before storing it to make reheating individual portions easier.

When reheating, using an oven or toaster oven is preferable to maintain the crispiness of the crust. By following these steps, you can ensure that your leftover pizza stays fresh and delicious for as long as possible. 

Potential Health Risks of Eating Old Pizza 

Eating old pizza can pose potential health risks due to the growth of harmful bacteria such as Salmonella, Listeria, and E. coli. When pizza is left at room temperature for too long, bacteria can multiply quickly, leading to foodborne illnesses.

Additionally, the ingredients of the pizza, particularly the dairy and meat toppings, can spoil and cause food poisoning if consumed past their expiration date. Mold can also develop on old pizza, which can cause allergic reactions and respiratory issues in some individuals.

To avoid these health risks, it is important to consume pizza within a safe timeframe and properly store any leftovers in the refrigerator. 

Tips For Determining If Refrigerated Pizza is Still Safe to Eat

There are a few ways to determine if refrigerated pizza is still safe to eat. 

  • First, check the expiration date on the packaging. If it has passed, it’s best to toss the pizza.

  • Next, inspect the pizza for any signs of spoilage, such as mold, strange odors, or an off-color appearance. If the pizza looks or smells bad, it’s best to err on the side of caution and throw it away.

  • Additionally, if the pizza has been stored in the refrigerator for more than 3–4 days, it’s likely best to discard it to avoid any potential foodborne illness. When in doubt, it’s always safer to throw it out and opt for a fresh pizza. 

Reheating Methods For Old Refrigerated Pizza

There are several effective methods for reheating old refrigerated pizza to ensure it tastes just as delicious as when it was first made.

One popular method is to reheat the pizza in the oven. Preheat the oven to 375 °F and place the pizza slices on a baking sheet. Let them cook for about 10–15 minutes, or until the cheese is bubbly and the crust is crispy.

Another common method is to use a skillet on the stovetop. Simply heat a non-stick skillet over medium heat and place the pizza slices in the skillet. Cover the skillet with a lid and let the pizza cook for 4–5 minutes, or until the cheese is melted and the crust is crispy.

If you’re in a hurry, the microwave can be a quick and convenient option. Place the pizza slices on a microwave-safe plate and heat them for 30–45 seconds, or until the cheese is melted.

Regardless of the method you choose, it’s important to monitor the pizza closely to prevent it from burning or becoming too dry. With these reheating methods, you can enjoy your old refrigerated pizza as if it were freshly made. 

How to Tell if Your Pizza Has Gone Bad (5 Signs) 


It can be disappointing to open up your fridge and find that what was once a delectable pizza now looks suspect. But how do you really know if your pizza has gone bad?

There are a few telltale signs to look out for.

First, take a good whiff. If the pizza smells off or sour, it’s probably best to toss it. Next, check the texture. If the crust has become too soft or soggy, that’s another indication that the pizza is no longer good to eat.

Another sign of spoiled pizza is mold. If you see any green or white fuzz growing on the pizza, it’s time to say goodbye to that pie.

Additionally, if the toppings look discolored or overly greasy, that’s a surefire sign that the pizza is past its prime.

Lastly, if there are any signs of unusual sliminess or an excessively oily appearance, these are all clear indicators that your pizza has gone bad and should be thrown away. When in doubt, it’s best to err on the side of caution and avoid consuming questionable pizza to avoid food poisoning. 

Creative Ways to Repurpose Old Refrigerated Pizza 

Instead of throwing away old, refrigerated pizza, you can repurpose it in several creative ways

One option is to use the pizza as a base for a new dish, such as a pizza-inspired casserole. Simply chop up the pizza into bite-sized pieces and mix it with other ingredients like vegetables, cheese, and eggs before baking it in a casserole dish for a delicious and easy meal.

Another idea is to use the pizza as a stuffing for other foods, such as peppers or mushrooms. Simply remove the original filling and replace it with pieces of the pizza before baking for a fun twist on stuffed vegetables.

You can also turn the pizza into a savory bread pudding by tearing it into chunks and soaking it in a mixture of eggs, milk, and herbs before baking it in a dish for a unique and flavorful dish.

These creative repurposing ideas can give new life to old refrigerated pizza and prevent food waste. 

Nutritional Implications of Consuming Old Refrigerated Pizza

Consuming old refrigerated pizza can have several nutritional implications.

As the pizza sits in the refrigerator, the moisture from the toppings and dough can lead to the growth of bacteria and mold, potentially causing foodborne illnesses.

Additionally, the fat in the cheese and pepperoni on the pizza can become rancid over time, which may have negative effects on cardiovascular health. The process of reheating the pizza may also lead to the formation of harmful compounds such as acrylamide, a potential carcinogen.

Furthermore, the longer the pizza is stored in the refrigerator, the more likely it is to lose its nutritional value. The vitamins and minerals in the toppings, such as vegetables and meats, may degrade over time, diminishing the overall nutritional content of the pizza.

Moreover, when pizza is left in the fridge for an extended period, there is a risk of cross-contamination if it comes into contact with other foods or spills in the refrigerator. This can introduce harmful bacteria and lead to foodborne illnesses.

Overall, consuming old refrigerated pizza may put individuals at risk of ingesting harmful bacteria, mold, rancid fats, and potentially carcinogenic compounds.

It is important to consume perishable foods such as pizza within a safe timeframe to minimize the risk of foodborne illness and to ensure that the nutritional value of the pizza is preserved. 

Addressing Common Myths and Misconceptions Related to Refrigerated Pizza Safety 

There are several common myths and misconceptions related to refrigerated pizza safety that need to be addressed. Some people believe that pizza can be left out for long periods of time without refrigeration because it contains preservatives.

Additionally, there is a misconception that reheating pizza to a high temperature will kill any bacteria present. While reheating can help reduce the risk of foodborne illness, it is not a foolproof method for eliminating all bacteria.

It’s important to follow proper food safety guidelines and refrigerate pizza promptly to ensure it stays safe for consumption.
