What Happens if You Eat Sprouted Potatoes: A Guide

What Happens if You Eat Sprouted Potatoes?

If you eat sprouted potatoes, there is a potential risk of toxic effects due to the presence of solanine.

Solanine is a compound found in sprouted potatoes that can be toxic to humans if ingested in large quantities.

However, sprouted potatoes that are still firm, have small sprouts, and show no signs of wrinkling or shriveling are generally safe to eat.

It is important to cut off the sprouted parts and any soft spots before consuming sprouted potatoes.

Nevertheless, even with these precautions, there is still a chance of getting sick.

It is advised not to eat potato sprouts under any circumstances.

In cases where potatoes have become too spoiled to eat, they can be planted in a garden to yield fresh edible potatoes in the future.

To prevent potatoes from sprouting, store them in a cool, dark place, such as a paper bag to filter out light.

Additionally, sprouted potatoes may have a bitter taste due to the presence of glycoalkaloids.

Small sprouts can be removed, and the remainder of the potato can still be consumed.

However, large sprouts and growths should be discarded as they can be toxic.

If a potato has turned green beyond the skin, it should also be discarded.

Dark or discolored spots on the flesh can be cut out, and the rest of the potato can be safely eaten.

Severely blighted potatoes should always be thrown out to avoid potential illness.

Therefore, while precautions can be taken, it is best to avoid consuming sprouted potatoes to minimize any potential health risks.

Quick Tips and Facts:

1. Sprouted potatoes contain higher levels of solanine, a natural toxic compound that can cause symptoms such as nausea, diarrhea, and even hallucinations if consumed in large amounts.

2. If you eat sprouted potatoes that have turned green, you may experience a bitter taste due to the increased concentration of chlorophyll. This green color indicates an elevated presence of solanine as well.

3. Interestingly, the process of sprouting in potatoes is a defense mechanism against threats such as bacteria, fungi, and insects, as the sprouts contain higher levels of glycoalkaloids, including solanine, to deter these predators.

4. While some people suggest removing the sprouts from potatoes makes them safe to eat, it’s important to note that the solanine may have spread throughout the potato. Consequently, cutting off the sprouts may only reduce the concentration of solanine in the area where the sprouts were present.

5. The severity of solanine poisoning varies depending on several factors, including the individual’s sensitivity to solanine, the amount ingested, and the duration of exposure. While rare, severe solanine poisoning cases can lead to more severe symptoms such as difficulty breathing and even paralysis. Therefore, it is generally recommended to avoid consuming sprouted potatoes altogether.

Toxic Potential Of Sprouted Potatoes

Potatoes are a versatile and widely consumed staple food in many households. However, caution should be exercised when these tubers begin to sprout, as they have the potential to become toxic. Sprouting usually occurs at temperatures around 68 degrees Fahrenheit, triggering dormant buds to grow into shoots. While the sprouting process itself is natural, it can lead to the accumulation of a toxic compound called solanine.

Solanine is found in varying amounts in potato plants and acts as a defense mechanism against pests and insects. Although the concentration of solanine is usually low in mature and uncooked potatoes, sprouting can cause its levels to rise significantly. Ingesting large quantities of solanine can be toxic to humans, leading to symptoms such as nausea, vomiting, diarrhea, and even neurological issues in severe cases.


  • Toxins can build up in sprouted potatoes, making them potentially harmful if ingested in large quantities.
  • Sprouting occurs when dormant buds on potatoes start to grow into shoots, triggered by temperatures around 68 degrees Fahrenheit.
  • Solanine is a toxic compound found in varying amounts in potato plants, acting as a defense mechanism against pests and insects.
  • While solanine levels are usually low in mature and uncooked potatoes, sprouting can cause a significant increase in its concentration.

Safe Parameters For Consuming Sprouted Potatoes

While the toxicity of sprouted potatoes is a concern, all hope is not lost when you spot a sprout or two. Potatoes that are still firm, with relatively small sprouts and no signs of wrinkles or shriveling, are generally safe to eat. However, it is essential to take precautions before consuming them. To make sprouted potatoes safe for consumption, it is recommended to cut off the sprouted parts and any soft spots before cooking or eating them.

Nevertheless, it is important to note that even with these precautions, there is still a chance of getting sick. Cutting off the sprouted parts may reduce the solanine content, but it does not eliminate it entirely. Therefore, it is crucial to exercise caution and moderation when consuming sprouted potatoes, particularly if the sprouts are large or the potato exhibits signs of decay.

  • Cut off the sprouted parts and any soft spots
  • Exercise caution and moderation when consuming sprouted potatoes

Precautions When Eating Sprouted Potatoes

It is crucial to emphasize that under no circumstances should one consume potato sprouts. The sprouts themselves contain higher concentrations of solanine, rendering them more toxic than the rest of the potato. It is always best to remove the sprouts entirely before cooking or consuming the potato. Additionally, if the potato has turned green due to exposure to light, it is recommended to discard it if the green color extends beyond the skin.

Furthermore, any dark or discolored spots on the flesh of the potato should be cut out before consumption. The remaining flesh can still be eaten without fear of toxicity. However, if the potato is severely blighted or shows signs of rot, it is best to discard it entirely to avoid potential illness.

  • Remove potato sprouts before cooking or consuming
  • Discard green potatoes if the green color extends beyond the skin
  • Cut out dark or discolored spots on the flesh of the potato

Disposing Of Unfit Sprouted Potatoes

If the sprouted potatoes are too far gone to be consumed safely, all is not lost. These potatoes can actually be repurposed by planting them in a garden to grow fresh and edible potatoes in the years to come. By planting sprouted potatoes, you can transform them into productive assets rather than waste them.

However, if you do not have the means or desire to plant the sprouted potatoes, it is essential to dispose of them properly. This prevents any accidental consumption by yourself, pets, or wildlife, which could lead to potentially harmful effects. Properly dispose of unfit sprouted potatoes by placing them in a sealed plastic bag and discarding them in the trash.

Preventing Potato Sprouting

To prevent the sprouting of potatoes, it is crucial to store them in a cool and dark environment. A temperature of around 45 to 50 degrees Fahrenheit is ideal for minimizing sprouting. Storing potatoes in a paper bag can help filter out light, which further reduces the chances of sprouting.

Light exposure causes potatoes to produce chlorophyll, leading to the development of green coloration and increased solanine content. By properly storing potatoes and limiting their exposure to light, you can prolong their shelf life and reduce the risk of sprouting.

  • Store potatoes in a cool and dark environment.
  • Maintain a temperature of 45 to 50 degrees Fahrenheit.
  • Use a paper bag to filter out light and reduce sprouting.

Avoiding sprouting in potatoes is best achieved through prevention rather than dealing with a surplus of sprouted potatoes. By following proper storage techniques and minimizing light exposure, you can extend the shelf life of potatoes and reduce the risk of sprouting.

Handling Discoloration And Blight In Potatoes

Potatoes are prone to discoloration and blight, which can affect their safety for consumption. If you come across dark or discolored spots on the flesh of your potatoes, it is best to remove them by cutting them out. The remaining unaffected flesh can still be consumed safely.

Severely blighted potatoes, on the other hand, must be discarded promptly. Blight is a plant disease caused by various fungi and bacteria, which can compromise the quality and safety of the potato. Consuming severely blighted potatoes can lead to illness, making it imperative to remove and dispose of them to prevent any potential harm.

In conclusion, sprouted potatoes possess the potential to be toxic due to the solanine content they accumulate during the sprouting process. While sprouted potatoes with small sprouts and no signs of decay can still be consumed by cutting off the sprouted parts, caution should be exercised. Potato sprouts should never be eaten, and any signs of discoloration, blight, or decay should prompt their removal or disposal. By taking proper precautions and storing potatoes under the right conditions, you can enjoy the goodness of potatoes while minimizing the risk of toxicity.
