How Can You Tell If Sweet Potatoes Are Bad?

As sweet potatoes are a delicious and nutritious root vegetable, they are widely used in various dishes around the world.

Therefore, it is essential to know how to tell if your sweet potatoes have gone bad before you consume them.

Signs that Your Sweet Potatoes Have Gone Bad

  1. Mushy Texture: One of the most significant signs that your sweet potato has gone off is its texture. If it feels soft and mushy when touched or squeezed gently, then it’s no longer good for consumption.

  2. Wrinkled Skin: The skin of a fresh sweet potato should be firm and smooth without any wrinkles or cracks in it. However, if you observe wrinkles on its surface or find cracks extending deep into the flesh inside while peeling them off during preparation – then these may indicate spoilage.

  3. Discoloration: Freshly harvested tubers have vibrant orange color skin from outside with cream colored flesh inside; usually turning pale yellow after cooking due to chemical changes occurring during heating process – however older ones may turn brownish black with spots all over which suggest rotting already taking place within spoiling cells under skin tissue layer too!

  4. Foul Odor: Another straightforward way of telling whether your sweet potatoes have spoiled is by smelling them! If they give out an unpleasant odor resembling moldy earthiness mixed with sweetness – discard immediately as otherwise could lead down path towards food poisoning symptoms.

Do Not Eat Spoiled Sweet Potatoes

You should avoid consuming spoiled vegetables such as rotten or mold-infected foods at all costs. Eating spoiled sweet potatoes can lead to severe health problems, such as food poisoning and gastrointestinal issues.

The toxins produced by the bacteria that cause spoilage can be harmful to human health. Therefore, it's always best to err on the side of caution when dealing with questionable produce.

How To Store Sweet Potatoes?

Knowing how to store your sweet potatoes correctly is essential in extending their shelf life and preserving their quality. Here are some tips on how you can do so:

  1. Keep them in a Cool Place: The ideal temperature range for storing sweet potatoes is between 50-60°F (10-15°C). Avoid keeping them at room temperature or above because higher temperatures promote bacterial growth, leading to spoilage.

  2. Avoid Moisture: Excess moisture causes mold growth that ruins these roots quickly; keep them dry throughout storage duration after harvest until time of preparation – ideally within sealed plastic bags which absorb any excess humidity while allowing airflow inside for longer-lasting freshness!

  3. Do Not Refrigerate: Do not store raw sweet potatoes in the refrigerator – they are more susceptible towards cold injuries resulting from chilling injury due prolonged low temperatures like those experienced inside refrigerated compartments which could result cells rupturing causing softening and rotting eventually!

  4. Inspect Regularly: Regularly inspect your stored sweet potato tubers for signs of decay or damage – remove any damaged ones immediately before they start spoiling good ones nearby.


Sweet potatoes are a great vegetable with many benefits, but it’s important to know when they have gone bad before consuming them – especially if you want zero risks associated with consuming toxic substances generated within spoiling cells under skin tissue layer too!

In conclusion: Look out for mushy texture, wrinkled skin patches/spots/darkening colors/discoloration changes foul odor as clear indicators signifying spoilage has occurred already taken place; store your tubers properly by keeping them cool, dry and inspecting them regularly. By following these tips, you can safely enjoy the sweet goodness of your potatoes while avoiding any health risks associated with consuming spoilt produce.
