How To Tell if Leftover Pizza is Bad

Bad pizza due to melted toppings and grease

When trying to decide whether food has gone bad, your senses are your best judge. Here are the telltale signs that your pizza has gone bad, from the way it looks to the way it can taste.

Rancid Smell

Even if it might still look edible on the surface, you need to trust your sense of smell. If it stinks, it's time to throw it away. One of the appetizing qualities of pizza is its smell, so it would be a disservice for you to still

Mold on the surface

This one is a no-brainer. Once you notice mold starting to coat the surface of your food, you throw it away! Mold is not only disgusting, but it can also be dangerous for your health.

A hard and dry crust

This may not be a dealbreaker for some people, but a hard crust means that your pizza is halfway to becoming spoiled, if not way past its freshness.

A hard and dry crust could also mean that it has not been stored well, and there are already risks from that alone. There may be bacteria starting to grow on the surface, so it is best to stay on the safe side and get rid of it.

Bad sour and bitter taste

If the pizza appears edible, the crusts are not that hard, and it does not smell bad, you might think it is safe for consumption. However, a spoiled pizza will have the obvious sign that it has expired: if it tastes awful.

No one wants to eat an awful-tasting pizza, so do yourself a favor and do not eat it.

Liquified toppings

If the toppings no longer look fresh and they appear to be melting on the surface, it means bacteria have started growing underneath. It is time to get rid of it to prevent health risks and rid yourself of the horrible-looking food.

Freezer burns

Freezer burns indicate that your pizza has not been properly stored and sealed. Contaminants might have started growing on the pizza without you noticing, and it might already be unsafe for consumption.

Freezer burns happen if the food loses its moisture, but outside air manages to seep in. If air still managed to seep in, then bacteria might also have found their way.

Why You Should Never Eat Expired Pizza

If you insist on eating that leftover pizza because it doesn't look or taste bad, there are risks that can compromise your health. Here are the reasons why you should never try to eat spoiled pizza, or any food for that matter.

Food Poisoning

Expired frozen pizza is linked to E. Coli, the bacteria that causes food poisoning. This is why you should eat frozen pizza right away once you have thawed or heated it in the microwave.


Salmonella is found on bad chicken and meat, which are typically on pizza toppings. You can suffer from stomach cramps and fever from consuming pizza with expired toppings.


Diarrhea is one symptom of both food poisoning and salmonella. This happens when the bacteria has found its way to your digestive system. This is the last thing you want after a day of eating out.

Final Thoughts
