Can you eat 2-day old pizza?

In this brief study, we will answer the question, “can you eat 2- day old pizza?” and we will also discuss the storage of pizza at different temperatures.

Can you eat 2-day old pizza?

Yes, you can eat a 2- day old pizza but only if it has been stored in the refrigerator. If the pizza has been left at room temperature it may get spoiled in a few hours.

What is the maximum amount of time that leftover pizza is edible?

In today’s fast-paced world, it is common for us to disregard food safety warnings. It is recommended that any leftover pizza be wrapped or sealed and refrigerated or frozen within a certain time; otherwise, it should be discarded.

The following are the USDA’s guidelines for reheating leftover pizza:

  •         Room temperature pizza above 90 °F (32 °C): 1 hour
  •        Room temperature pizza below 90 °F (32 °C): 2 hours
  •         The refrigerated pizza below 40 °F (4 °C): 3 to 4 days
  •         The frozen pizza below 0°F (-18 °C): 1 to 2 months

Pizza left at room temperature

According to the United States Department of Agriculture, all perishable products, including pizza, are not safe to eat after being left at room temperature overnight for an extended time (USDA). This rule applies regardless of whether or not your pizza has any meat on it. 

Temperatures between 40 to 140 degrees Fahrenheit are considered “risk zones” by the USDA for perishable products stored at these temperatures. When a meal is left out in the “risk zone” for more than 20 minutes, the likelihood of contracting a food-borne illness more than doubles.

Pizza stored in the refrigerator

According to the USDA, pizza that has been chilled at a temperature below 40 degrees Fahrenheit is safe to eat for up to four days after it has been prepared and frozen. The average slice of pizza may be consumed after five days in the refrigerator; but, after four days, the likelihood of getting a food-borne illness increases, and no one wants that. It would be much more prudent to just order another pizza.

How to reheat leftover pizza?

When reheating pizza, the best technique is not to use the microwave, but rather to place it on a pan and hover it over a flame for about one minute. After that, place the pizza in the oven and warm it for five to eight minutes at 400 degrees. As a consequence, you’ll have delicious leftover pizza that tastes just as good the second time around.

Is it possible to store leftover pizza in the freezer?

Yes, it is possible to do so. Wrapping food tightly or storing it in a shallow meal prep container can help to prevent freezer burn and food from drying out completely.

Pizza leftovers should be eaten within one to two months after being stored in the freezer. They can be securely stored for a longer time, but the risk is that the food will continue to dry up and lose its flavor.

Why does pizza taste better the next day?

Soups, stews, curries, and pizzas all benefit from cooling and resting in the refrigerator for a few hours or overnight. Oil and water do not mix, which is beneficial to cold pizza since it improves the flavor of the dish. As the oil cools, it forms a barrier that helps to keep the moisture and flavor of the pizza intact. In the oven, the melted cheese solidifies on top of the dough, forming a protective shell around the spicy purée.

It is because the fat does not flow out of the crust and dough that it gets contained inside and adds to the overall taste of the pie. It is the concentrated fats and flavors that make leftover pizza taste so much better the next day, rather than the fresh ingredients.

If the pizza is heated, does it destroy the germs on the surface?

If you leave pizza out overnight, it becomes a breeding ground for food-borne pathogens. Bacteria reproduce and multiply at a fast pace, contaminating food in a short amount of time.

Toxins generated by the bacteria may pose a threat to those who already have weakened immune systems. Even after the meal has been heated to 165°F, the toxins produced by bacteria remain on the surface.

Even though the bacteria will die, their toxic metabolites will continue to exist. The pizza must be adequately cooked to 165°F, which is not always easy to do when making pizza from scratch.
