What Happens if You Eat a Bad Potato?
If you eat a bad potato that contains high levels of solanine, a toxic compound found in potatoes, you may experience symptoms of solanine poisoning.
These symptoms can include vomiting, diarrhea, and other signs of food poisoning.
While recorded cases of solanine poisoning are rare, there have been documented cases of solanine toxicity resulting in deaths.
It is important to note that potatoes naturally produce solanine as a defense mechanism against insects and disease.
Potatoes that have turned green or have been stored for extended periods of time have increased solanine levels and should not be eaten in large quantities.
Additionally, it is advised not to eat green potatoes below the skin, as 30-80% of the solanine in potatoes develops in and close to the skin.
To reduce the risk of solanine toxicity, peel potatoes before cooking and avoid consuming potatoes that exhibit signs of spoilage.
Quick Tips and Facts:
1. The green tint on a potato is caused by a chemical called solanine, which develops when potatoes are exposed to sunlight. Consuming green potatoes can lead to symptoms such as stomach cramps, headaches, and even paralysis if ingested in large quantities.
2. Historically, potatoes were blamed for the outbreak of the infamous ‘Potato Blight’ in Ireland during the mid-19th century. The blight, caused by a fungus known as Phytophthora infestans, destroyed the potato crops, leading to widespread famine and the loss of millions of lives.
3. Contrary to popular belief, potatoes are not root vegetables but underground stems known as tubers. This distinction places them in the same family as plants such as tomatoes and peppers.
4. Potatoes were the first vegetable to be grown in space. NASA successfully grew potatoes aboard the International Space Station in 2015, as part of ongoing research into sustainable food production for long-duration space missions.
5. In 1995, a potato became the first vegetable to be grown from seed in space. This milestone was achieved on the space shuttle Columbia, where astronauts used a specialized growth chamber to cultivate the plant.
Solanine Content In Potatoes And Factors That Increase It
Potatoes are a delicious and versatile vegetable that we often include in our meals. However, it is essential to be aware of the potential risks associated with consuming bad or spoiled potatoes. One of the main concerns is the presence of solanine, a toxic compound that can be found in potatoes.
Solanine is a naturally occurring glycoalkaloid that acts as a defense mechanism for the potato plant against insects and disease. When potatoes undergo stress or damage, such as mechanical injury or being stored for extended periods of time, their solanine content tends to increase. This means that old or damaged potatoes are more likely to contain higher levels of solanine.
It is important to note that solanine is primarily concentrated in and around the skin of the potato. Therefore, removing the skin before cooking can significantly reduce the glycoalkaloid intake. In fact, approximately 30-80% of the solanine develops close to the potato skin. This is a crucial factor to consider when preparing potatoes to minimize the risk of solanine poisoning.
Effects Of Cooking Methods On Solanine Levels In Potatoes
Now that we have discussed the factors contributing to higher solanine content in potatoes, it is important to understand how various cooking methods can affect solanine levels. While boiling, cooking, and frying have minimal impact on solanine levels, microwaving can actually reduce the alkaloid content by approximately 15%.
However, the effect of deep frying on solanine content varies based on the temperature and duration of frying. Deep frying at 150 °C (302 °F) does not result in any measurable change in solanine levels. On the other hand, deep frying at 210 °C (410 °F) for 10 minutes leads to a significant loss of approximately 40% of solanine present in the potato.
This information is valuable for choosing an appropriate cooking method to minimize solanine intake.
- Boiling, cooking, and frying have minimal effects on solanine levels.
- Microwaving can reduce solanine content by approximately 15%.
- Deep frying at 150 °C (302 °F) does not affect solanine levels.
- Deep frying at 210 °C (410 °F) for 10 minutes can cause a 40% decrease in solanine content.

Microwaving And Deep Frying: Their Impact On Solanine Content
Microwaving potatoes can reduce the solanine content by around 15%. This is good news for those who prefer to use their microwaves to prepare their potatoes. However, it is important to note that microwaving alone may not eliminate all potential risks associated with solanine.
Deep frying potatoes can have varying effects on solanine content depending on the temperature. Deep frying at 150 °C (302 °F) does not result in any measurable change in solanine levels. However, deep frying at 210 °C (410 °F) for 10 minutes can cause a significant reduction of approximately 40% of the solanine present in the potato. Therefore, if you choose to deep fry potatoes, ensuring that they are cooked at the appropriate temperature and duration can help reduce solanine intake.

The Role Of Potato Peeling In Reducing Glycoalkaloid Intake
Peeling potatoes before cooking them significantly reduces the intake of glycoalkaloids, including solanine. A significant amount of solanine is concentrated in and near the potato skin. Therefore, removing the skin can greatly decrease the potential risk of solanine poisoning.
However, it is important to note that even after peeling, residual solanine may still be present in the potato. Therefore, it is essential to ensure that the potato is properly cooked at suitable temperatures to further reduce any remaining solanine content.
- To reduce glycoalkaloid intake, peel potatoes before cooking.
- Concentrated solanine is found in and near the potato skin.
- Proper cooking at suitable temperatures reduces solanine content.

Notable Cases Of Solanine Poisoning And Symptoms
While recorded human poisonings from solanine poisoning are rare, it is important to note that there have been documented cases throughout history that highlight the potential dangers. Between 1865 and 1983, approximately 2000 cases of solanine poisoning were reported, resulting in 30 deaths.
One notable case occurred in Germany, where soldiers fell ill after consuming potatoes. Although there were no fatalities, this incident demonstrates the potential risks associated with solanine poisoning. Additionally, in Scotland in 1925, a tragic incident took place where a five-year-old child and two family members died after consuming green potatoes, which have elevated solanine levels.
In 1979, there was a mass solanine poisoning incident that occurred in the U.K. when 78 boys at a boarding school exhibited symptoms after consuming improperly stored potatoes. Seventeen of them were hospitalized, highlighting the importance of properly storing potatoes to prevent solanine poisoning. Similarly, in 1984, there was another incident in Canada where 61 schoolchildren and teachers experienced symptoms of solanine toxicity after consuming baked potatoes with high levels of solanine.
Symptoms of solanine poisoning include vomiting and diarrhea, which resemble food poisoning. This similarity in symptoms makes it possible that there are undiagnosed cases of solanine toxicity. It is important to note that fatalities from solanine poisoning have been documented, particularly in undernourished individuals.
Warning Signs And Precautions: Green Potatoes And Other Nightshade Plants
Potatoes that have turned green in color should not be eaten in large quantities, as this is an indication of elevated solanine levels. When potato tubers are exposed to light, they undergo a natural process that causes them to turn green and increase solanine production. Therefore, it is important to keep potatoes stored in a cool, dark place to prevent them from becoming green and toxic.
It is also worth noting that other plants belonging to the nightshade family, such as the berries of Solanum dulcamara, can also contain solanine and pose a risk if consumed in large quantities.
In conclusion, consuming a bad or spoiled potato that contains high levels of solanine can lead to solanine poisoning. Understanding the factors that increase solanine content in potatoes, the effects of different cooking methods on solanine levels, and the precautions to take can help mitigate the risk. Caution should be exercised when consuming green potatoes or other nightshade plants, and if symptoms of solanine poisoning occur, seeking medical attention is crucial to ensure proper diagnosis and treatment.
