Can a Potato Go Bad?
Yes, a potato can go bad.
Uncooked potatoes can last anywhere from 1 week to a few months, depending on how they are stored.
Signs of spoilage include softness, mushiness, musty or moldy odor, and foul smell.
Cooked potatoes can also spoil, with a strong odor or visible mold as indicators.
Spoiled potatoes can harbor harmful bacteria and may cause foodborne illness.
To minimize spoilage, potatoes should be stored in cool, dark places with proper air circulation.
Quick Tips and Facts:
1. A potato can indeed go bad, but before it does, it can sprout a unique green shoot that contains the toxin solanine. Consumption of high levels of solanine can cause nausea, headaches, and even paralysis.
2. Potatoes were not always a staple food in Europe. They were introduced to Europe from the Americas in the late 16th century, but many Europeans initially rejected them due to misconceptions that they caused diseases and were poisonous.
3. The world’s largest potato weighed in at a whopping 18 pounds and 4 ounces (8.3 kilograms)! This giant spud was grown in the United Kingdom in 1795 and would have made a considerable amount of fries.
4. Potatoes played a significant role during the Gold Rush in the mid-1800s. Miners in California discovered that potatoes were an excellent source of Vitamin C, preventing scurvy and helping to sustain their health in the absence of fresh fruits and vegetables.
5. In 1995, potatoes became the first vegetables to be grown in space! NASA’s Space Shuttle Columbia carried a small crop of potato plants as part of an experiment to understand how plants could be cultivated in space for future long-duration missions.
Origins And Cultivation Of Potatoes
Potatoes, scientifically known as Solanum tuberosum, have a rich history deeply intertwined with the native peoples of the Andes mountains in South America. Dating back thousands of years, these indigenous communities were the first to cultivate this versatile crop. From the fertile soils of Peru and Bolivia, potatoes made their way across the globe through various explorations and trade routes.
Today, thousands of potato varieties are cultivated worldwide, each with its unique taste, texture, and culinary applications. From the classic russets to the vibrant purple Peruvian potatoes, these tubers have become a staple in many cuisines. Whether it’s the creamy texture of Yukon Gold or the waxy texture of red potatoes, there is a potato variety to suit every taste preference.
Storage Duration For Uncooked Potatoes
The storage duration of uncooked potatoes largely depends on how they are stored. Ideally, uncooked potatoes should be stored in a cool, dark, and dry place away from direct sunlight. Cooler temperatures, such as a cellar or pantry, help extend their shelf life compared to storing them at room temperature.
Under proper storage conditions, uncooked potatoes can last anywhere from one week to a few months. However, it’s important to note that different potato varieties have varying storage capabilities. Some varieties, like the new potatoes, are more perishable and should be consumed within a week of purchase or harvest. On the other hand, starchy potatoes, such as russets, have a longer storage life and can last several months if stored correctly.
Shelf Lives Of Different Potato Types
Different potato types have different shelf lives. Here is a general guideline for the shelf lives of common potato varieties:
-
Russet Potatoes: These starchy potatoes are excellent for baking and have a long shelf life. When stored properly, russet potatoes can last up to several months.
-
Yukon Gold Potatoes: Known for their creamy texture, Yukon Gold potatoes can last up to a few months if stored in cool and dry conditions.
-
Red Potatoes: With their thin, delicate skin, red potatoes are more perishable compared to other varieties. They typically have a shelf life of a few weeks to a couple of months.
-
New Potatoes: These are young potatoes harvested early in the season. New potatoes have a shorter shelf life than mature potatoes and should be consumed within a week of purchase or harvest.
It’s important to note that these shelf lives are estimates, and proper storage conditions greatly influence the longevity of potatoes.

Signs Of Spoilage In Potatoes
Potatoes, like any other food item, can go bad if not stored or handled correctly. There are several signs to look out for to determine if a potato has spoiled. These signs include:
- Softness: If the potato feels soft or mushy when touched, it is likely spoiled and should not be consumed.
- Odor: Potatoes that have a musty or moldy odor indicate spoilage and should be discarded.
- Foul Smell: If the potato emits a foul smell, it is a clear indication of spoilage.
- Sprouts: While sprouted potatoes are still safe to eat, it is advisable to remove the sprouts, as they contain toxic glycoalkaloids. Consuming large quantities of these compounds can be harmful.
- Green Parts: Potatoes with green spots or green skin should be cut away before consumption. The green color indicates the presence of a toxic substance called solanine, which can cause illness if ingested in large amounts.
Risks And Precautions For Cooked Potatoes
While cooked potatoes may not show obvious signs of spoilage, it is important to be aware of the potential risks associated with consuming them. Cooked potatoes, particularly if stored for a long period or at incorrect temperatures, can contain harmful bacteria like salmonella, listeria, botulism, and staphylococcal food poisoning.
To minimize the risk of foodborne illness, it is crucial to follow these guidelines:
- Consume cooked potatoes within four days.
- Always reheat them to an internal temperature of 165°F (74°C) to kill any bacteria that may be present.
- Discard any cooked potatoes that have a strong odor or visible mold immediately.
In case of spoiled potatoes causing foodborne illness, symptoms may include fever, stomach cramps, muscle aches, nausea, vomiting, and diarrhea. If you experience any of these symptoms after consuming improperly stored or spoiled potatoes, seek medical attention promptly.
- Consume cooked potatoes within four days.
- Reheat cooked potatoes to an internal temperature of 165°F (74°C) to eliminate bacteria.
- Discard cooked potatoes with a strong odor or visible mold immediately.
“If in doubt, throw it out.”
Best Practices For Storing Potatoes
To ensure the longevity and quality of potatoes, it is essential to follow proper storage practices. Here are some best practices for storing potatoes:
-
Raw potatoes should be stored in a cool, dark, and dry place, preferably at temperatures between 45°F (7°C) and 50°F (10°C). Avoid storing them on the counter or in open areas exposed to light and heat.
-
Use a container that allows for air circulation, such as a breathable paper bag or a mesh vegetable storage bag, for storing uncooked potatoes. Avoid sealing them in airtight bags or containers, as this can lead to excess moisture and spoilage.
-
Fresh potatoes should not be stored in the refrigerator or freezer as the low temperatures can negatively impact their texture and flavor.
-
Always separate potatoes from other produce to minimize exposure to ethylene gases, which can accelerate sprouting or spoilage. This can be done by storing potatoes in a separate drawer or away from fruits and vegetables that produce ethylene gas.
By following these storage practices, you can prolong the shelf life of your potatoes and reduce the risk of spoilage-related issues.
