How to Tell If Potatoes Are Bad

Must read

If you are looking to buy potatoes, there are a few things you should look for. These include Earthy smells, soft and wrinkled skin, and a green sprout. You should also check to see if the potato is fresh or has been rotten. Also, watch for solanine poisoning.

Green sprouts

If you find green sprouts on potatoes, it may be time to discard them. They contain glycoalkaloids, a natural toxin, and are harmful to your health.

Sprouts can be found on potatoes both raw and cooked. You can easily remove them with a paring knife.

Potatoes love to sprout when they are exposed to warm temperatures. They will begin to produce chlorophyll, a green pigment, which adds a bitter taste to mashed potatoes.

Besides chlorophyll, potatoes also produce a natural toxin called solanine. Solanine is a neurotoxin that can cause gastrointestinal symptoms and even headaches. The best way to remove these toxins is to peel the potatoes.

Alternatively, you can use a vegetable peeler. Most vegetable peelers have a nub at the end of their blade that you can use to dig out sprouts.

Sprouts are easy to remove from potatoes, especially when you are cleaning them. Just make sure to rinse them under running water to get rid of any bacteria.

Another way to determine if a potato is bad is to check for signs of mold or rot. Rotten potatoes have a smell that can be very unpleasant. Also, rotten potatoes can be very hard to cut in half.

Generally, you should throw away potatoes that have long green shoots. However, if you can only see a small sprout, it is still safe to eat.

While potatoes are not usually toxic when they are harvested, they can become spoiled if they are not stored correctly. Toxins are typically concentrated in the peel and around the sprouts.

Green potatoes can be harmful to your health, but they are not dangerous to eat. When you notice the appearance of green sprouts on your potatoes, it is a good idea to discard them immediately.

Soft and wrinkled

When you buy potatoes at a store, you may wonder if they’re safe to eat. While they may be delicious, you don’t want to eat a potato that is soft or wrinkled. If you’re not careful, you could end up with a rotten potato. Not only are they mushy, they can also be contaminated with toxins. This could cause food poisoning or even hospitalization.

The best way to avoid consuming soft and wrinkled potatoes is to cook them immediately. You can also try eating them with sprouts. Although it’s not the healthiest option, they are still safe. However, be aware that if you store sprouted potatoes too long, they will turn into mush.

Wrinkled potatoes are not always bad. Some potatoes, such as sweet potatoes, can be eaten while shriveled. Still, you’ll want to make sure to get them off your plate before they go mushy.

There’s no need to throw out a perfectly good potato, though. Even a slightly soft potato can be useful in mashed potatoes or other recipes. That’s because they’re not as mushy as their aging counterparts.

Green or yellow potatoes are not necessarily bad. These are just signs that your potatoes have been exposed to too much light. If you’re unsure of their condition, you can peel them to find out.

Moldy and sour cooked potatoes should be thrown out. Their smell is an indication that they’ve gone off. They also look foul.

One of the signs that you’re dealing with a bad potato is a green tinge to their skin. If your potato has green spots, you should cut them out. Of course, if you have no green spots, the rest of the potato is fine to eat.


Potatoes are a popular vegetable in many countries. However, this food item can also go bad. To avoid wasting your money, it’s important to know how to tell if potatoes are moldy. Moldy potatoes are extremely unhealthy. They can cause your stomach to ache and even make you feel sick.

The best way to tell if potatoes are moldy is to look for small bumps. These bumps can be a sign of early blight, which causes the potato to soften. Sprouts are another indicator of premature spoilage.

Another sign of rot or mold is a foul odor. If the potatoes smell sour or have an earthy, moldy scent, they are probably spoiled.

You can find mold on cooked and raw potatoes. It can appear in different colors, such as grayish white, bluish grey, or reddish brown.

If you see a green spot, it’s a sign of a toxin, which may be present in the potato. This toxin may be dangerous. Solanine is a poison that can cause serious health problems.

If you don’t see any signs of rotting, it’s safe to assume that you have a good potato. There are some things you can do to extend the life of your potato. First, you should store it in a cool and dry place. Second, you should use a breathable container.

The best way to keep your potatoes fresh is to store them in a well ventilated location, such as a basement or pantry. Store them away from other fruits and vegetables that can cause the potatoes to ripen prematurely.

A wrinkly skin will not change the taste of a potato, but it can be a sign of rot. Rotted potato is hard to cut in half, and the insides may be soft and mushy.


Potatoes give off an earthy smell. This is because they contain geosmin, an organic compound that is also found in the soil. It is not only an odor, but it is a molecule that gives the potato its flavor.

The same molecule is responsible for the sour smell that is present in spoiled cooked potatoes. While it isn’t necessarily harmful to your health, it isn’t something to enjoy.

Solanine, the chemical that produces the earthy smell, is actually a poison. When it gets into your system, you may experience diarrhea, fever, abdominal cramps, dizziness, headaches, and even unconsciousness.

You can prevent the smell from forming by storing your potatoes in a cool, dry, and dark place. Store the potato in a breathable bag to increase its shelf life.

Potatoes with soft spots, wrinkled skin, or a foul odor are likely rotting. They are not safe to eat and can lead to mold. If you do find a bad potato, the University of Illinois Extension recommends throwing it out.

To remove the earthy smell from your potatoes, Idaho Potato suggests putting 1 tablespoon of lemon juice into a gallon of water. This will ward off the fungus, thereby preventing the rotting process.

Potatoes have a natural toxin called solanine. It is only a small amount that causes adverse reactions. Symptoms of solanine poisoning include nausea, stomach cramps, headaches, dizziness, and unconsciousness. However, this does not mean that you should avoid potatoes altogether.

As a rule of thumb, potatoes with green spots should be discarded. These spots will not cause you to vomit, but they will definitely turn your potatoes green.

If you are unsure of the best way to discard your rotting potatoes, ask a trusted friend or a family member. You can also check the label on the potato to see if the tainted part has been removed.

Solanine poisoning

If you are not careful when eating potatoes, you can get solanine poisoning. This is a very dangerous occurrence. It can cause a range of symptoms from headaches to drowsiness. In some cases, it even causes loss of consciousness. You should always take immediate medical help if you suspect you have solanine poisoning.

Solanine is an alkaloid found in potatoes. The concentration is higher in green tubers than in ripe ones. To minimize the likelihood of solanine poisoning, you should store the potatoes properly. Ideally, it should be stored in a cool, dry place with low humidity.

During the growth period, solanine accumulates in potato tubers. When it gets too high, it is toxic. Generally, the amount increases three to four times in spring. Symptoms of solanine poisoning include headache, stomach pain, vomiting, nausea, weakness, dizziness, and confusion.

People with solanine poisoning should avoid eating any unripe or unwashed potatoes. Similarly, people should not eat tomatoes that are not fully ripe.

Potatoes have solanine in their peels and under the peel. However, it is not found in the center of the potato. Instead, it is found in the upper one-eighth of the skin. A large baked potato weighs about a pound.

To reduce the amount of solanine in your potatoes, peel them thoroughly. Never thin the peel. Also, keep your potatoes in a cool, dry, dark place to prevent their solanine from accumulating.

To avoid solanine poisoning, you should never eat potatoes with green pigment. Whenever you notice the green tint, you should discard it.

Solanine is a plant alkaloid that affects the nervous system, kidneys, urinary tract, and respiratory system. Moreover, it can also cause joint disease.
