How To Tell If A Sweet Potato Is Bad? Sweet potatoes are not only delicious but also packed with nutrients, making them a popular choice for many dishes. However, like any perishable food item, sweet potatoes can go bad if not stored or handled properly. In this article, we will explore the signs of a bad sweet potato, how to store them correctly to prolong their freshness, and what happens if you accidentally consume a spoiled one.
Signs of Freshness in Sweet Potatoes
What a Fresh Sweet Potato Should Look Like?
- Firm Texture: Fresh sweet potatoes should feel firm to the touch, without any soft or mushy spots.
- Vibrant Skin Color: Look for sweet potatoes with a vibrant, consistent skin color, free from dark spots or blemishes.
- Lack of Visible Blemishes: Inspect the skin for any cuts, bruises, or blemishes. Fresh sweet potatoes should be smooth and unblemished.
How Freshness Impacts Taste and Nutrition
Fresh sweet potatoes not only taste better but also retain more of their nutritional value. They’re richer in vitamins and minerals, making them a healthier choice for your meals.
How Long Before Sweet Potato Goes Bad?
The shelf life of sweet potatoes depends on several factors, including how they are stored, the temperature, and the initial quality of the potato. On average, sweet potatoes can last anywhere from 2 to 4 weeks when stored in a cool, dry place. However, by following proper storage guidelines, you can extend their freshness for several months.
How To Tell If A Sweet Potato Is Bad?
Appearance
One of the most obvious signs of a bad sweet potato is a change in its appearance. A healthy sweet potato should have smooth, firm skin without any wrinkles or soft spots. If you notice any of these issues, it’s a sign that the sweet potato is past its prime.
Smell
Fresh sweet potatoes have a slightly sweet and earthy aroma. If your sweet potato emits an unpleasant, musty, or moldy smell, it’s an indication that it has gone bad. Trust your nose; if it doesn’t smell right, don’t use it.
Texture
When you touch a sweet potato, it should feel firm and dense. A bad sweet potato will become soft and spongy. Press your fingers gently against the skin; if it leaves an indentation, the potato is no longer good to eat.
Mold and Sprouts
Mold and sprouts are clear signs of a sweet potato that has gone bad. If you notice any fuzzy green or white patches on the skin, it’s mold. Moldy sweet potatoes should be discarded immediately. Additionally, if the sweet potato has sprouted, it’s an indication that it’s past its prime. While you can remove the sprouts and still consume the potato, the quality may have deteriorated.
Color
Color can be a useful indicator as well. While sweet potatoes come in various shades, such as orange, purple, and white, the color should be vibrant and uniform. Any signs of discoloration, especially dark spots or patches, could mean the potato is no longer good to eat.
Taste Test
Sometimes, appearance and smell may not provide definitive answers. In such cases, a taste test can be helpful. If you cook or bake a sweet potato and it tastes off, has an unusual bitterness, or a strange aftertaste, it’s a sign of spoilage. Trust your taste buds; they can often detect subtle changes.
How To Store Sweet Potatoes The Right Way?
1. Temperature
Sweet potatoes are sensitive to temperature fluctuations. Store them in a cool, dark place with a temperature range of 55-60°F (13-15°C). Avoid refrigeration, as temperatures below 50°F (10°C) can cause the potato’s starches to convert to sugar, resulting in an unpleasant taste.
2. Humidity
Maintaining the right humidity level is crucial. Aim for a humidity level of around 75-80% to prevent the sweet potatoes from drying out or sprouting.
3. Avoiding Moisture
Excess moisture can lead to rot. Keep sweet potatoes dry and avoid placing them in plastic bags, as they can trap moisture. Instead, store them in a breathable container or a perforated plastic bag.
4. Proper Ventilation
Ensure good air circulation around your sweet potatoes. Use a mesh or wire basket to store them, allowing air to flow and preventing the buildup of moisture.
5. Keep Away from Ethylene-Producing Fruits
Ethylene gas can speed up sweet potato spoilage, so store them away from fruits like apples and bananas.
What Happens If You Eat A Bad Sweet Potato?

Even if the sweet potato isn’t severely spoiled, it may still cause gastrointestinal discomfort, such as bloating, gas, or indigestion.
