How To Tell If A Sweet Potato Is Bad

When it comes to enjoying sweet potatoes, freshness is key. However, it’s not always easy to tell if a sweet potato has gone bad. That’s why it’s important to know the signs of spoilage and how to properly store these nutritious tubers.

If you’re wondering whether your sweet potato is still good to eat, look out for these telltale signs of spoilage: oozing, softness, squishiness, discoloration, off-putting smell, and sprouts. Additionally, be sure to remove any moldy spots before cooking. A dry and oxidized interior is another indicator of a bad sweet potato. By knowing what signs to look for, you can ensure food safety and enjoy your sweet potatoes with peace of mind.

Key Takeaways:

  • If a sweet potato is oozing, soft, squishy, discolored, smelly, or has sprouts, it is time to discard it.

Visual Indicators of Spoilage

When it comes to determining if a sweet potato is bad, visual indicators play a crucial role. By closely inspecting the sweet potato, you can spot signs of spoilage that indicate it is no longer safe to consume.

Here are the key visual indicators to look out for:

  • Wrinkling: A bad sweet potato may display wrinkled skin, indicating that it has lost moisture and is dehydrated.

By keeping an eye out for these visual indicators, you can easily identify a bad sweet potato and avoid any potential health risks.
