How To Tell If a Potato Is Not Bad

It may seem difficult to tell whether a potato is bad or not, but there are certain symptoms to look for that can indicate that your potato is in danger. These include green spots, sprouts, and a musty smell. These symptoms may indicate a more severe problem, such as mold.


There is a simple way to determine if a potato has sprouted. Potatoes will typically turn green when exposed to light. This is an indication of increased levels of toxins in the potato. To avoid consumption of this type of potato, you should remove the green tint using a paring knife. The sprouted potato can still be eaten or cooked if it is not wrinkly. However, if you do notice a green tint, it is best to throw it out.

Sprouts are a sign that the potato is nearing the end of its shelf life. If the potato has green skin under the peel, it is likely past its prime. This is also a sign that it is soft and wrinkly. Depending on the size and location of the sprouts, you can easily remove them. If they are small, you can simply remove them with a potato peeler. Otherwise, you can plant the sprouted potato in your garden.

Although potato sprouts may contain glycoalkaloids, which are toxic to humans, these sprouts can be fine to eat if you remove them before cooking. Sprouts also contain solanine, which is a digestive irritant that can be poisonous to small children. A small child exposed to these toxins can suffer vomiting and paralysis. If you do choose to eat a sprouted potato, make sure to remove the sprouts as soon as possible.

Musty smell

Is there a way to get rid of the musty smell of a potato? The smell of rotten potatoes can be difficult to get rid of, but there are a few things you can do. First, you can clean the cabinet with a mixture of dish soap and water. Make sure to ventilate the cabinet afterward. You should also discard the old potato.

If a potato has a musty smell, it probably means it’s spoiled. This happens when the food was stored improperly. This isn’t always immediately apparent, but it’s a sign that a potato is going bad. Often, the smell isn’t as strong as it is with other foods, but it can still be an indicator of rotting.

Fresh potatoes have an earthy, nutty aroma, and they smell like fresh soil. However, rotten potatoes have an unpleasant musty odor that makes them unfit for eating. In addition, rotten potatoes will leak liquid and lose their shape. If you notice any of these symptoms, you should discard the potato as soon as possible.

Green Spots

Green spots on a potato are a warning sign that it is rotten. Potatoes that develop green spots should be thrown away. The spots are caused by a mild toxin, called solanine. The spots are harmless if they are small, but if they are large, they should be thrown out immediately.

Potatoes can get green spots naturally because they are exposed to sunlight, but these spots are also caused by high solanine levels. While solanine is not toxic in small amounts, eating too much of it can make you sick. The substance is especially harmful to children. It can cause physical symptoms and even death. So, when buying potatoes, you should make sure to look for green spots on them.

If you see a small green spot, it is likely to be spoiled. It can also smell moldy and bitter. In addition, the spots may be green in color. In such cases, you should throw the potato. The green spots on a potato indicate that it contains toxic solanine.


One of the easiest ways to tell if a potato is bad is by looking at its wrinkles. Potatoes age just like human skin, and this causes them to wrinkle. Wrinkled potatoes are not good to eat. If you see any wrinkling, throw it away right away. Other symptoms include mushy insides. If you still want to eat a potato, try cooking it first and then checking for wrinkles.

A wrinkled potato will have a mushy inside. It will also have a bad smell. If it has a musty smell, discard it immediately. While wrinkles do not affect the taste, they can be a warning sign that a potato is going bad. You may also notice sags or spots on the surface. If these signs are present, throw away the potato.

Potatoes with wrinkles are bad because they contain toxins known as glycoalkaloids. Although these compounds have a small amount of antibiotic and health benefits, they are toxic to humans if consumed in large amounts. While you can eat a potato with wrinkles if it still looks healthy, don’t eat one that is sprouted or wrinkly.

Longer Than 5 Inches

If you’ve ever wondered how to tell if a potato is bad, you’ll be pleased to know that there are some simple ways to make sure your potatoes remain tasty and safe. One of the most important ways is to keep them stored properly. It is essential to store your potatoes in cool, dry, dark places. This will help preserve their freshness and reduce food waste. Proper storage can also help prevent food-borne illnesses and food poisoning.

Too-warm storage conditions and direct sunlight drastically reduce a potato’s shelf life. In addition, potatoes stored in plastic packets won’t have adequate air circulation and will turn brown sooner than they should. A bad potato will have green skin and sprout “eyes.” It will also look wrinkled and feel mushy, and it will smell rotten.

Green Spots – Toxic

Potatoes with green spots are tainted with solanine, a toxic substance. This substance is produced when the potato is exposed to too much light, and when the potato is stored in an insufficient way. In addition, potatoes can be damaged during harvesting or post-harvest processing. They may also be exposed to extreme temperatures or sunlight. Because of this, it’s a good idea to peel potatoes before cooking them. However, you should avoid potatoes that are emerald green.

To protect your potatoes from solanine, store them in a cool, dark area. You can use a solution of dishwasher detergent and water. To use the solution, add 2 tablespoons to a quart of water. The solution will protect your potatoes for two to 10 days. Then, refrigerate them to keep them fresh longer. In order to store potatoes safely, make sure to check them frequently.

Potatoes with green spots are toxic. They contain high levels of solanine, which is produced by exposure to sunlight. Solanine is a bitter toxin that can cause vomiting and diarrhea if consumed in large doses. While small green spots on potatoes can be removed without causing any harm, larger patches should be discarded immediately.

Green Spots – Sign of Spoilage

If you notice green spots on your potatoes, it’s probably time to throw them out. This is an early sign of spoilage because the potatoes contain a toxin called solanine. This substance makes the potatoes sour and bitter. Organic potatoes, however, often sprout after they’re harvested.

While green spots on potatoes are an early sign of spoilage, they’re not the only sign of aging. You can also smell solanine from potatoes. It’s not poisonous in small amounts, but in large amounts, it can make you sick. Luckily, you can avoid solanine by peeling them before cooking.

Another sign of spoilage is a musty or moldy smell. While a pungent, earthy smell is an indication of a fresh potato, a musty or moldy smell signals that the potato is past its prime. You can smell the difference by using your nose. If the potato has a foul smell, you know it’s time to throw it away.
