Signs of a Bad Sweet Potato
It's essential to know the first signs of spoilage to avoid consuming rotten sweet potatoes.
The first thing to check is the skin of the sweet potato. Good sweet potatoes should have a firm skin without any cracks or brown spots. Any discoloration on the skin of sweet potatoes is a sign of spoilage. Additionally, the presence of white substance or white sap on the skin is a sign of harmful bacteria.
Here are some additional signs that indicate your sweet potato has gone bad:
- Softness: A spoiled sweet potato often becomes mushy or develops soft spots. If it feels mushy or has soft spots, it's a no-go.
- Wrinkles or Shrinking: Wrinkles or shrinkage are indications of dehydration or rotting.
- Discoloration: Spoiled sweet potatoes may develop dark or white spots or change color.
- Smell: A musty, rotten, or unpleasant odor is a clear sign of rotting. If it smells funky, toss it out.
- Mold or Weird Growth: Mold or unusual growths on the sweet potato are a definite sign of spoilage.
If your sweet potato exhibits any of these signs, it's safest to discard it to avoid the risk of food poisoning.
Black Spots or Wrinkly Ends
If your sweet potato has black spots or dark spots or lightly wrinkly ends, it may be a sign of mold or decay. It's best to cut off any affected areas and discard them. If the majority of the sweet potato is still good, you can still use the remaining parts.
However, it's important to check the rest of the sweet potato for any additional signs of spoilage, such as softness or a foul odor. It's always better to err on the side of caution and discard any sweet potatoes that show signs of spoilage to avoid getting sick. When in doubt, throw it out!

Sprouted Sweet Potatoes
If your sweet potato has sprouted, remove the sprouts before eating. They can taste bitter and may contain toxins.
What to Do With a Bad Sweet Potato
If you discover a spoiled sweet potato, discard it immediately. Never try to salvage parts of the sweet potato that show signs of spoilage. It's best to dispose of spoiled sweet potatoes in your trash or compost bin.
What Happens If You Eat a Bad Sweet Potato
Eating a bad sweet potato can lead to food poisoning, which isn't fun for anyone. Symptoms of food poisoning can emerge a few hours to several days after eating a spoiled sweet potato and may include nausea, vomiting, watery or bloody diarrhea, abdominal pain, cramps, and fever. In severe cases, symptoms might also include chills, weakness, muscle aches, and sweating. Not worth the risk!
While most people recover from food poisoning within a few days, in some severe cases, it might require medical attention or hospitalization. It's always best to seek medical advice.
All in all, the risk of potential illness and discomfort far outweighs the benefits of consuming a questionable sweet potato. It's always best to err on the side of caution and discard any sweet potatoes that show signs of spoilage.
Best Practises for Buying Sweet Potatoes
When buying raw sweet potatoes, look for sweet potatoes that are firm, smooth, and free from any bruises or blemishes. Avoid sweet potatoes that have any signs of mold or decay.
Best Ways to Store Sweet Potatoes
To prevent your sweet potatoes from going bad, it's important to store them properly. Here are some tips for storing fresh sweet potatoes:
- Dry Place: Store sweet potatoes in a cool, dry area away from direct sunlight and moisture. A pantry or cupboard is the best option.
- Paper Bag: To keep sweet potatoes fresh longer, store them in a paper bag. This allows for air circulation, which helps prevent moisture build-up.
- No Refrigeration: Sweet potatoes should not be stored in the refrigerator, as the cool temperature can alter their taste and texture.
- No Storing with Other Produce: Sweet potatoes should not be stored with other produce, as they release ethylene gas that can cause other produce to go bad more quickly.
- Do Not Wash: Do not wash sweet potatoes before storing. They should be kept dry until ready to use.
It's best to store sweet potatoes in a dry, cool, and dark place. The ideal temperature is between 55-60°F (12-15°C). This can be achieved by storing sweet potatoes in a pantry or cupboard away from direct sunlight.
Shelf Life
When stored correctly, sweet potatoes can have a relatively long shelf life. Whole sweet potatoes can last up to three to five weeks at room temperature. Cut sweet potatoes should be stored in an airtight container in the refrigerator and consumed within four days.
Moreover, organic sweet potatoes are the best quality and have a longer shelf life compared to conventional ones.
If you have excess sweet potatoes that you cannot consume within their shelf life, you can freeze them for later use. Freezing uncooked sweet potatoes is not recommended as they may lose their texture and flavor during the freezing process. However, cooked sweet potatoes freeze well and can be reheated for later use.
How To Freeze
To freeze sweet potatoes, cut them into small pieces and place them in a freezer-safe container. You can also add a squeeze of lemon juice to prevent discoloration. For best results, use the frozen sweet potatoes within six months.
Extra Tips for Using Up Sweet Potatoes
If you have sweet potatoes that are nearing the end of their shelf life, here are some tips for using them up:
- Roast Them: Roasting sweet potatoes brings out their natural sweetness and can be a delicious side dish or snack. Sweet potato fries are also a great way to use up sweet potatoes.
- Make Soup: Sweet potato soup is a comforting and nutritious meal that can be made with just a few ingredients.
- Bake Them: Sweet potatoes can be baked and topped with your favorite toppings for a tasty and filling meal.

By knowing how to spot a bad sweet potato and how to store them properly, you can enjoy their many benefits without worrying about spoilage. Remember, always discard any sweet potatoes that show signs of spoilage, and try to use your sweet potatoes before they go bad. Enjoy the versatile and nutritious sweet potato without waste or worry!
