So let’s get rolling!

First, let’s discuss the perils of eating spoiled potatoes.



Did you know that cooked potatoes are a great risk of getting spoiled?

If you eat a cooked potato that has turned stale, then there is a high chance of food poisoning.

Once the potatoes are cooked, they begin to harbor bacteria and pathogens that can cause severe sickness like staphylococcal food poisoning, botulism, listeria, salmonella, and much more.

Well, if you keep them in the pantry at the right temperature, it will last up to three to five weeks.

Potato shelf life depends on various factors such as the humidity of your climate, type of potato, the preparation method (boiled, fried, or cooked), selling date, and much more.

Suppose you just bought potatoes and didn’t use them for a week, it will still be edible. Yes, they are good for your health even if the selling date has lapsed.

Now, the main question arises, “How do you know when potatoes go bad?

In the next section, find the red flags to know the potatoes quality is deteriorating.



Even after keeping the shelf life of potatoes in mind, you will still have to keep an eye on these veggies for any kind of spoilage.

It completely normal for spuds to smell nutty or earthy, but a moldy, foul, or musty odor is a sign of spoilage.

And sometimes, a spud may look fresh from the outside but on the inside, it may have a bad spot or a blemish.

A weird smell coming out of a fresh-looking spud is a clear warning too!

So here is how to determine whether the potato had gone bad or still edible:

1. Wrinkly Surface

Want to know the very first sign of your potatoes turning stale?

Well, the wrinkly surface is the first stage!

You might notice its skin turning soggy and mushy. If that is the case, we suggest you throw the spud right away because keeping them with the other potatoes might contaminate the fresh ones.

These signs are noticeable, so if you notice the fresh spuds are still free from blemishes or bruises and are frim, they are edible.

If not, then it is time to throw them away.

2. Molds

The potatoes should be kept in a proper place because mold tends to grow on the surface when they are exposed to humidity.

You might also notice discoloration.

What to do when it happens?

First of all, you will have to check the other areas of mold. You must also inspect if the mold has reached the insides of this vegetable. 

If you find a mold growing into multiple molds, then they are no longer fresh to consume. So it is best to throw them.

3. Sour or Musty Scent

Generally, fresh potatoes have an earthy smell. On the other hand, the spoiled ones have a strange, moldy, or musty odor. 

Sometimes, the potatoes will look fresh, but don’t get fooled. Even the fine-looking ones from the outside, which do not have a wrinkly surface, can turn stale once it starts to smell foul.

Even fuzzy or bluish-grey, white, red, black, brown spots on the potatoes are clear indications of your potatoes have gone bad.

So the best thing to do here is to discard them as they are no longer edible.

4. Spuds Begin to Sprouts

If the potatoes are kept in the humid climate for too long, they will begin to develop new white sprouts with tiny green leaves at the top.

Later on, the fresh spuds will no longer remain fresh and lose their vitamins, minerals, and nutrients.

However, green sprouts do not necessarily mean they are spoilt. It indicates that their quality is deteriorating.

They may lack some nutrients, but they are still edible. So it is best to use them immediately before their quality drops even further.

But if they are already ruined, get rid of them already and plant the new sprouts.

5. Green Spots

Sometimes, the potatoes get exposed the direct sunlight or very cold temperature for an extended amount of time, and that develops a green tinge on their surface.

But that is completely normal!

So what should you do?

If you notice a green spot, you can cut off that part, and you are good to go. Later, you can use the rest of the potato for cooking.

Wondering, “How long do potatoes last at room temperature or in the fridge?”

Then let’s uncover it in the next section!



1. Storing Potatoes at room temperature

The best way to keep the raw and uncooked potatoes is by storing them at room temperature.

When you keep them in a dark and cool place (cooler than room temperature by warmer than the fridge), the bag of potatoes can last up to two months.

Fascinating, right?

But if you don’t have an unheated basement, you will probably have to stick to the room temperature.

So at room temperature, the fresh spuds will remain fresh for two weeks.

Here is how to store them:

Keep the potatoes loosely covered in a cardboard box, mesh bag, or paper bag for proper air circulation.

Now, do you want to know how long can cooked potatoes last in the fridge?

Then, let’s unearth the alternative to room temperature, which is the fridge in the next sub-topic.

2. Storage of Potatoes in Fridge

Keeping potatoes in the fridge is not the right place to store fresh spuds, but sometimes, we don’t have any choice. 

Humidity, hot conditions, and lack of pantry space are the main reasons you want to refrigerate your potatoes. 

For whatever reason, you have decided to store them in the fridge; it will last for three weeks.

But storing them in the fridge will cause the starch in the potatoes to turn sweet, and you don’t want your spicy food to taste sweet, now do you?

Seven Simple and Easy Ways to Store a Bag Full of Potatoes

Potatoes, onions, and garlic have a longer shelf life than other vegetables.

However, the spud’s life also depends on how you store it. The procedure might help them to delay the spoilage and last longer.

Below, we have shown the seven best ways to store the potatoes or any starchy vegetables so they can stay fresh and tasty for a longer period.

2. Keep potatoes in a humid, cool, and dark place. 

You need to provide the right environment and temperature for potatoes.

Experts reveal that the ideal temperature for storing them is between forty-five to fifty degrees F.

The other factors that play important roles are light, humidity, and temperature.

Generally, it is best to store these produce in a dark, dry, and cool place such as a pantry or a cupboard.

It will keep them fresh for up to three to five weeks.

Looking for another great option?

You can place the potatoes in your dry and well-ventilated basement. But make sure to protect it from heavy exposure to light, be it artificial or natural because they may develop green spots.

3. Avoid storing potatoes in the fridge. 

We recommend you avoid storing raw potatoes in the refrigerator.

As we said before, the extra-cool temperature turns its starch into sugar and shortens the shelf-life.

So keep them in the fridge is not a great idea.

4. Keep them away from onions, bananas, or apples.

Another helpful tactic to preserve the potatoes is by keeping them away, and by “away” we mean far away from apples, bananas, and onions.
