The inner flesh generally contains much lower levels.
Consuming large amounts of these toxins may cause symptoms such as:
Nausea
Vomiting
Diarrhea
Stomach pain
Headache
Fever
Most cases are mild, but higher exposures can lead to more serious symptoms.
Does Cooking Remove the Toxins?
Unfortunately, no.
Boiling, baking, frying, or roasting may reduce some toxin levels, but cooking does not completely eliminate solanine and chaconine.
That’s why it’s important to remove sprouts, eyes, and green areas before cooking a lightly sprouted potato.
Raw sprouted potatoes should never be eaten.
What About Green Potatoes?
A green potato isn’t necessarily toxic because of its color.
The green pigment comes from chlorophyll, which is harmless. However, chlorophyll often develops under the same conditions that increase solanine and chaconine levels—primarily exposure to light.
If only a small area is green, you can cut it away.
If a large portion of the potato is green, it’s safest to discard it.
How to Prevent Potatoes From Sprouting
Proper storage can significantly extend the life of your potatoes.
Store Them in a Cool, Dark Place
Ideal storage locations include:
A pantry
A cupboard
A basement storage area
Avoid direct sunlight and excessive heat.
Keep Potatoes Away From Onions
Onions release gases that can accelerate sprouting. Store them separately whenever possible.
Use Breathable Containers
Potatoes need airflow to stay fresh.
Good storage options include:
Mesh bags
Cotton bags
Wire baskets
Avoid sealed plastic bags, which can trap moisture and encourage spoilage.
Buy Only What You’ll Use
Buying in bulk may seem economical, but purchasing more potatoes than you can reasonably use often leads to waste.
Other Signs a Potato Has Gone Bad
Sprouting isn’t the only indication that a potato should be discarded.
Throw away potatoes that are:
Soft or Mushy
Fresh potatoes should feel firm and solid.
Deeply Wrinkled
Significant shriveling is a sign of age and moisture loss.
Moldy or Covered in Dark Spots
Mold growth, extensive bruising, or dark discoloration indicates spoilage.
Bad-Smelling
Fresh potatoes have a mild, earthy scent.
If a potato smells musty, moldy, or unpleasant, discard it immediately.
