Can a Sweet Potato Go Bad?
Yes, a sweet potato can go bad.
It can spoil quickly if not stored properly due to its high moisture content.
Signs of a bad sweet potato include a soft, mushy texture, discolored skin with sprouts or mold, and a foul smell.
Mold on the skin, especially black, yellow, or orange mold, indicates that the sweet potato is rotten.
Consuming a spoiled sweet potato can lead to food poisoning symptoms such as nausea, vomiting, diarrhea, and stomach cramps.
Therefore, it is important to properly store and inspect sweet potatoes to ensure they are not spoiled before consuming them.
Quick Tips and Facts:
1. Contrary to popular belief, sweet potatoes do not technically go bad. They may, however, become softer and develop an unpleasant taste and odor over time.
2. Sweet potatoes are an ancient crop, believed to have been cultivated for over 5,000 years. They were first domesticated in Central and South America.
3. Sweet potatoes are not related to regular potatoes. They belong to the morning glory family and are, in fact, more closely related to flowers than to traditional tubers.
4. The orange-fleshed sweet potatoes commonly consumed today were developed in the early 20th century by a botanist named George Washington Carver, who was also known for his work with peanuts.
5. Despite their name, sweet potatoes are not actually potatoes. Potatoes belong to the nightshade family, while sweet potatoes are part of the morning glory family.
Signs Of A Bad Sweet Potato
Sweet potatoes, with their high moisture content, can spoil quickly if not stored properly. It’s essential to know the signs of a bad sweet potato to avoid consuming spoiled food. One of the most noticeable signs is a soft and mushy texture. When you squeeze a sweet potato, it should feel firm and have a slight resistance. However, if it feels squishy or collapses under pressure, it is most likely spoiled.
Another visual indicator of a bad sweet potato is discolored skin. Look for any sprouts or mold on the skin, as this suggests that the sweet potato has gone rotten. Mold comes in various colors, and black, yellow, or orange mold indicates spoilage. Additionally, a spoiled sweet potato may have a darker green, gray, or black skin that appears dull and wrinkled. These changes in color and texture are clear indications that the sweet potato should be discarded.
Furthermore, pay attention to the smell of the sweet potato. A fresh sweet potato should have a neutral smell. If you detect a foul odor coming from the sweet potato, it is most likely spoiled. Trust your sense of smell and discard any sweet potatoes with an off-putting scent.
Identifying Rotten Sweet Potatoes
Identifying whether a sweet potato has gone bad requires careful observation of its exterior and interior. The skin of a spoiled sweet potato may show signs of mold, liquid seeping out, and a soft, mushy texture. Mold growth, especially black mold, indicates that the sweet potato is no longer safe to consume. Any liquid oozing out of the sweet potato is not a good sign and suggests spoilage. Additionally, a soft and mushy texture is a clear indication of decay.
It is important to note that not all discoloration indicates spoilage. Superficial dark spots on the skin are generally safe to eat. However, if the discoloration runs deep into the sweet potato, it could be a result of fungal infestation, and it is advisable to avoid consuming it.
When cutting open a sweet potato, inspect the flesh for signs of mold, liquid, and texture. Mold growth on the inside, especially if it is black, is a definite sign that the sweet potato has gone bad. Excessive liquid with a foul smell is also an indicator of spoilage. In terms of texture, if the sweet potato feels overly soft and mushy, it has likely started to rot.

Proper Storage Of Sweet Potatoes
Proper storage is crucial for maintaining the freshness and quality of sweet potatoes. Here are some tips to keep in mind:
-
Raw sweet potatoes should be stored in a cool, dark, and well-ventilated space, such as a pantry. Make sure the area is dry to prevent spoilage caused by moisture.
-
When storing raw sweet potatoes, it’s best to brush off any dirt instead of washing them. Washing can introduce moisture, which speeds up spoilage. However, if you peel or cut the sweet potatoes, you can store them in cold water for up to a day to prevent browning.
-
To maximize the shelf life of cooked sweet potatoes, it’s recommended to store them in an airtight container or bag in the refrigerator. This helps preserve their moisture and prevents bacterial growth. Remember to consume cooked sweet potatoes within 3-5 days for freshness and safety.
-
If you have excess cooked sweet potatoes and don’t plan to consume them within the recommended time frame, freezing is an option. Frozen cooked sweet potatoes can last 6 to 12 months if properly frozen. Store them in airtight containers or freezer bags to prevent freezer burn and preserve their quality.
Remember, proper storage is essential for maintaining the taste, texture, and nutritional value of sweet potatoes.
Handling Sprouted Sweet Potatoes
Discovering sprouts on sweet potatoes does not necessarily mean they are no longer usable. If you notice small sprouts in a confined area and the sweet potato is still firm, you can salvage it by simply cutting off the sprouted part. However, it is crucial to discard a sweet potato with extensive sprouting or when the texture feels soft and mushy. These signs indicate spoilage and make the sweet potato unfit for consumption.
When handling sprouted sweet potatoes, it’s important to inspect the rest of the tubers. Discard any sweet potatoes showing signs of spoilage, such as mold or a foul odor, even if they do not have sprouts. It’s best to err on the side of caution and prioritize your health and safety.
- Cut off small sprouts on firm sweet potatoes.
- Discard sweet potatoes with extensive sprouting or soft texture.
- Check for signs of spoilage like mold or foul odor.

Freezing And Refrigerating Cooked Sweet Potatoes
Proper storage techniques for cooked sweet potatoes can extend their freshness and usability. To refrigerate cooked sweet potatoes, transfer them to an airtight container or bag. This prevents moisture loss and the absorption of odors from other foods in the refrigerator. Cooked sweet potatoes refrigerated in this manner can last up to a week.
If you have surplus cooked sweet potatoes that you do not plan to consume within a week, freezing is an excellent option. Before freezing, ensure the sweet potatoes are completely cooled. Place them in airtight containers or freezer-safe bags, removing as much air as possible to prevent freezer burn. Properly frozen cooked sweet potatoes can maintain their quality for up to six months in the freezer.

Frequently Asked Questions
Is a sweet potato bad if it’s white inside?
A white inside of a sweet potato does not indicate that it is bad or unsafe to consume. In fact, the white liquid that may be present is simply a mixture of carbohydrates and sugars within the potato. This phenomenon is perfectly normal and poses no harm to your health. Enjoy your sweet potato without any concerns!
How do you know if a sweet potato has gone bad?
To determine if a sweet potato has gone bad, it is important to inspect it thoroughly. Check for soft spots or indentations on the potato, as these may indicate rot. Additionally, keep an eye out for any discoloration such as black spots or patches, as this may be a sign of spoilage or mold. Finally, pay attention to the smell of the sweet potato – if it emits a foul or musty odor, it is likely spoiling.
How long does it take for a sweet potato to go bad?
The shelf life of sweet potatoes can vary depending on how they are stored. If kept at room temperature in a pantry, sweet potatoes can typically last between 3 to 5 weeks. However, for lasting freshness, it is recommended to store them in the refrigerator where they can remain good for about 2 to 3 months. Another option for extending their longevity is freezing them, which can further extend the storage time.
Do sweet potatoes turn white when bad?
No, sweet potatoes do not turn white when they are bad. In fact, the presence of a milky substance on sliced sweet potatoes does not indicate spoilage but rather the release of sap. This sap, which is a combination of sugar and starch mixed with moisture, escapes through the knife cuts on the vegetable. Rather than signaling decay, the sap is an indicator of the natural sweetness of the sweet potato.
