Are Potatoes Safe to Eat After They Sprout?
No, potatoes that have sprouted are not safe to eat.
Sprouting indicates that the potato has higher levels of toxins called solanine and chaconine, which can cause symptoms such as vomiting, abdominal pain, diarrhea, and even death.
Green spots on potatoes also indicate higher toxin levels, so it is best to toss out any potatoes with sprouts or green patches.
Cooking does not destroy these toxins, so it is not advisable to prepare or eat potatoes with sprouts or green parts.
To prevent sprouting, it is recommended to store potatoes in a cool, dark, and well-ventilated place away from onions.
Quick Tips and Facts:
1. Ancient Egyptians worshipped potatoes as symbols of fertility and prosperity. They believed that eating sprouted potatoes would bring good luck and abundance.
2. The green color that sometimes appears on the skin of sprouted potatoes is caused by a buildup of solanine, a natural toxic chemical. While small amounts of solanine are harmless, consuming large quantities can cause nausea, vomiting, and even paralysis.
3. Potatoes that have sprouted tend to have a slightly sweeter taste due to the conversion of starches into sugars. This sweetness can be desirable in certain dishes, such as desserts or mashed potatoes.
4. If you find your potatoes have sprouted, you can prevent further sprouting by storing them in a cool, dark place with good ventilation. Avoid storing them near onions, as the gases released by onions can accelerate the sprouting process.
5. Contrary to popular belief, removing the sprouts and the eyes of a potato does not make it safe to eat. The toxic solanine can still be present in other parts of the potato, so it’s better to dispose of the entire potato if it has sprouted extensively or has a bitter taste.
Toxic Compounds In Potatoes: Solanine And Chaconine
Potatoes, a staple food for many, are generally safe and nutritious. However, it’s crucial to be aware that they contain natural toxins called solanine and chaconine. These toxins, belonging to the glycoalkaloid class of compounds, are most concentrated in the eyes, green skin, and sprouts of the potato.
Solanine and chaconine serve as natural defense mechanisms, protecting the potato from pests and diseases. Although usually present in small amounts and unlikely to cause harm, high levels can be risky to human health.
Avoidance Of Green Color In Potatoes
Green color in potatoes is a visible sign of excess glycoalkaloid concentration and should be avoided. When potatoes are exposed to light, chlorophyll pigments are produced, indicating the presence of increased levels of solanine and chaconine.
To minimize the risk of consuming toxic potatoes, it is advised to discard those that exhibit a greenish hue. While it may be tempting to simply remove the green parts, it is important to note that these toxins can penetrate the entire potato and are not easily eliminated through surface removal.
Sprouting And Green Spots As Indicators Of Toxicity
Sprouting and the presence of green spots on potatoes serve as clear indicators of higher toxin levels. When a potato sprouts, it means that it is undergoing a natural process of growth, leading to an increase in glycoalkaloid content. The same applies to the green spots, as discussed earlier.
It is crucial to understand that consuming sprouted or green potatoes can result in the ingestion of elevated levels of solanine and chaconine, thereby increasing health risks.
Symptoms Of Consuming Toxic Potatoes
Consuming toxic potatoes can have adverse effects on the human body. Symptoms may include vomiting, abdominal pain, irregular bowel movements, diarrhea, headache, brain fog, redness, confusion, or fever. In severe cases, death from toxic potato consumption has been documented.
If you experience any of these symptoms after consuming potatoes, especially sprouted or green ones, it is important to seek medical attention immediately.
Importance Of Discarding Sprouted Or Green Potatoes
To protect yourself and your loved ones from the potential risks associated with toxic potato consumption, it is best to discard potatoes that have sprouts or green patches. Tossing them out ensures that you do not expose yourself to elevated levels of solanine and chaconine.
While it is possible to remove sprouts and green parts with a sharp paring knife, this method is not foolproof and leaves room for the unintentional consumption of toxins. Therefore, it is not recommended.
Tips For Preventing Potato Sprouting And Preserving Freshness
To prevent potatoes from sprouting, it is advisable to buy them as needed, rather than in bulk. Storing potatoes in a cool, dark, and well-ventilated place away from onions helps maintain their freshness and reduces the likelihood of sprouting.
Refrigeration or freezing of potatoes before cooking should be avoided, as this can cause a buildup of solanine. Instead, keep potatoes loose and unwashed until ready to cook in order to preserve their freshness and minimize the risk of toxin accumulation.
In conclusion, while potatoes are generally safe to eat, it is important to be aware of the potential risks associated with sprouting and green patches. By understanding the toxic compounds present in potatoes, recognizing the indicators of toxicity, and following proper storage and preparation practices, you can ensure the safety of your potato consumption.
- Being well-informed and cautious is crucial when it comes to enjoying this versatile and delicious staple food.

Frequently Asked Questions
Can you still eat a potato that has sprouted?
Yes, you can still consume a potato that has sprouted, provided that it is firm, displays small sprouts, and doesn’t exhibit signs of shriveling or wrinkles. In such cases, removing the sprouted parts and any soft spots will render the potato safe for consumption. However, it’s crucial to note that even with these precautions, there is still a potential risk of getting sick. In contrast, if your potato has sprouted extensively and shows signs of shriveling, it is best to discard it as it has deteriorated beyond consumption.
When should you not eat potatoes?
It is advisable to not eat potatoes that have soft spots, dark spots, sprouts, or a green color. If any of these characteristics are present on a potato, it is best to remove them before preparing the potato for your dish. If the potato has long sprouts, feels soft, appears wrinkled, or contains numerous dark spots, it is recommended to discard it entirely.
Can I boil a sprouted potato?
Yes, you can boil a sprouted potato after cutting off the sprouts and ensuring they are not overly mushy. However, if the potato has turned fully green, it is advisable to purchase a fresh one instead. Green potatoes may indicate the presence of solanine, a toxic compound that can cause nausea and other adverse effects if consumed in large amounts.
Is solanine destroyed by cooking?
Solanine, a toxic compound found in green potatoes, is not eliminated by boiling but can be effectively destroyed through frying. Fortunately, solanine poisoning is quite rare as people generally avoid consuming green potatoes due to awareness of this issue. Additionally, consuming up to 5 grams of green potato per kilogram of body weight per day does not seem to result in immediate illness.
