When Potatoes Turn Toxic
Most people don’t think twice about leaving potatoes in the pantry for weeks—or months.
But letting them sit too long can actually make them dangerous to eat.
Potatoes naturally contain solanine, a toxin that protects them from pests.
In high amounts, solanine can cause nausea, headaches, and even more serious issues. “Those innocent spuds sitting in your pantry could make you sick.”
Warning Signs Your Potatoes Are Bad
Several clear signs can help you spot when a potato has gone from safe to sketchy:
- Green Tint: “If the whole thing is looking like the Grinch, toss it.” Green coloring means too much light exposure and rising solanine levels.
- Sprouts: “If your potato looks like it’s trying to grow arms? Get rid of it.” Sprouts also increase toxins like chaconine.
- Wrinkled or Soft: A fresh potato should feel firm. “Who wants to eat a sad, wrinkly potato anyway?”
- Foul Smell: A musty or sour odor means bacterial rot. “Do not—I repeat, do not—try to cook it.”
- Mushy or Wet: If it feels squishy or leaks, throw it out.
How to Keep Potatoes Fresh
To prevent spoilage, store potatoes in a cool, dark, dry place—never the fridge. “Cold temps actually turn the starches into sugar, which messes with their taste and texture.” Use them within a few weeks and avoid sealed plastic bags that trap moisture.
