Visible sprouts or “eyes” forming

A bitter taste or unusual odor

Even if the potato still feels firm, these indicators suggest it could be unsafe to eat. Never assume firmness equals freshness.

How to Reduce the Risk

Since solanine develops when potatoes are exposed to light or stored improperly, proper handling makes a big difference:

Store in a cool, dark, and dry place – Avoid direct sunlight, which accelerates sprouting. A paper or burlap bag is better than plastic, which traps moisture.

Don’t refrigerate – Cold temperatures convert potato starch into sugar, altering taste and texture without preventing sprouting.

Use potatoes quickly – Buy smaller quantities to avoid long storage periods. The longer they sit, the greater the chance of sprouting.

Cut generously if needed – If only small sprouts are visible, you can cut away the affected areas deeply. But if there are many sprouts or widespread green patches, it’s safer to discard the potato entirely.

Final Thoughts

Potatoes may seem harmless, but when they sprout, they carry a real risk. Solanine poisoning is rare but dangerous, especially for children and the elderly. By learning how to spot early warning signs and practicing safe storage, you can continue enjoying this beloved food without putting your health in jeopardy.
