Leaving our pizza out and eating it at another time is something we've all been guilty of at some point or another. But is pizza actually safe to eat after it's been sitting out for a while? Well, it depends on how its been stored.

If your pizza has been sitting at room temperature...

According to the U.S Department of Agriculture (USDA), all perishable foods, including pizza, are not safe to eat after sitting at room temperature overnight. This rule holds true whether your pizza has meat on it or not. By leaving your pizza out at room temperature, you are increasing your risk of being contaminated by food borne illnesses.

The USDA indicates a "danger zone" for perishable foods stored at temperates between 40 degrees Fahrenheit and 140 degrees Fahrenheit. The number of food borne illnesses can double every 20 minutes that a food is left out in the "danger zone."

According to the USDA, if your pizza has been refrigerated at a temperature lower than 40 degrees Fahrenheit, it's safe to eat up to four days. If you want to eat a slice that's been sitting in the fridge for five days, it's generally okay too—but after four days your risk of getting a food borne illness increases and who wants that? It's much safer to just order another pizza.
