Introduction to Potato-Borne Diseases
Potatoes are one of the most widely consumed foods globally, and they’re a staple in many cuisines. While they’re generally considered safe to eat, there are certain risks associated with consuming old or poorly handled potatoes. The main culprit behind these risks is a group of toxins and pathogens that can develop in potatoes as they age. These toxins and pathogens can cause a range of diseases, from mild gastrointestinal issues to life-threatening conditions.
The Science Behind Potato Toxicity
To understand the diseases that can be contracted from old potatoes, it’s essential to grasp the science behind potato toxicity. Potatoes contain a range of compounds, including glycoalkaloids, which are naturally occurring toxins that can be harmful to humans. The two main glycoalkaloids found in potatoes are solanine and chaconine. While these compounds are generally present in small amounts, they can increase significantly as potatoes age or become damaged.
Glycoalkaloids and Their Effects on Human Health
Solanine and chaconine are both toxic to humans, and consuming high amounts can lead to a range of symptoms, including nausea, vomiting, diarrhea, and abdominal pain. In severe cases, glycoalkaloid poisoning can cause more serious health issues, such as respiratory failure, cardiac arrest, and even death. The risks associated with glycoalkaloids are particularly high in certain populations, including pregnant women, young children, and individuals with compromised immune systems.

What diseases can you get from eating old potatoes?
Eating old potatoes can lead to various health issues, primarily due to the presence of toxic compounds that develop as the potatoes age. One of the main concerns is the production of solanine, a glycoalkaloid that can cause a range of symptoms, from nausea and vomiting to headaches and diarrhea. Solanine is produced naturally by potatoes as a defense mechanism, but its concentration increases when potatoes are exposed to light, become green, or start to sprout.
The consumption of old potatoes containing high levels of solanine can lead to solanine poisoning, which, in severe cases, can cause more serious health issues, including neurological problems and even death in extreme cases. It’s also worth noting that while solanine is the primary toxin associated with old potatoes, other pathogens such as bacteria and molds can also develop on improperly stored potatoes, leading to additional health risks. Therefore, it’s crucial to carefully inspect potatoes before consumption and avoid eating any that show signs of aging, such as sprouting, green skin, or an off smell.
How do old potatoes become contaminated with diseases?
The contamination of old potatoes with diseases can occur through several routes. One common way is through the invasion of bacteria, fungi, or other pathogens when the potato’s skin is damaged. This can happen during the harvesting process, storage, or handling. Moisture, improper storage conditions, and physical damage can all facilitate the entry and growth of these pathogens. For instance, if potatoes are stored in a humid environment, they become more susceptible to fungal infections, such as those caused by Phytophthora infestans, which is responsible for potato blight.
In addition to external pathogens, the internal environment of an aging potato can also become conducive to the growth of harmful bacteria and molds. As potatoes age, their cellular structure breaks down, leading to an increase inwater content and a decrease in their natural defense mechanisms. This can create an ideal environment for the proliferation of Clostridium botulinum, for example, which can produce a toxin leading to botulism in humans if ingested. The risk of disease from old potatoes can be minimized by ensuring they are stored in well-ventilated, cool, and dry conditions, away from direct sunlight and moisture.
What are the symptoms of disease from eating old potatoes?
The symptoms of disease or poisoning from eating old potatoes can vary depending on the type and amount of toxin or pathogen consumed. For solanine poisoning, common symptoms include gastrointestinal issues such as nausea, vomiting, diarrhea, and abdominal pain. These symptoms can range from mild to severe and typically appear within 24 hours after consumption. In more severe cases, solanine poisoning can lead to neurological symptoms, including dizziness, confusion, and in extreme cases, paralysis or respiratory failure.
It’s essential to recognize these symptoms early and seek medical attention if they persist or worsen over time. If the disease is caused by bacterial or fungal infections, the symptoms can be broader and may include fever, chills, and in severe cases, life-threatening complications. For example, botulism from contaminated potatoes can cause muscle weakness, drooping eyelids, facial weakness, and difficulty swallowing or speaking, requiring immediate medical intervention. The diverse range of potential symptoms underscores the importance of handling and consuming potatoes safely.
Can you prevent disease from old potatoes by cooking them?
Cooking old potatoes can reduce the risk of disease to some extent, but it’s not a foolproof method for eliminating all toxins. For example, heat can denature some proteins and kill certain pathogens, such as bacteria and viruses, making cooked potatoes safer to eat than raw ones. However, solanine, the toxin associated with green or sprouting potatoes, is heat-stable and cannot be completely removed by cooking. This means that even thoroughly cooked old potatoes can still pose a health risk if they contain high levels of solanine.
It’s also important to note that the effectiveness of cooking in reducing disease risk depends on the cooking method and the temperature achieved. Boiling or baking can kill many pathogens, but if the potatoes are not heated evenly or to a sufficient temperature, some bacteria can survive. Furthermore, if the cooking water is not discarded (in the case of boiling), toxins like solanine can leach into the water and still cause poisoning. Therefore, while cooking can make potatoes safer, it’s crucial to select potatoes that are fresh, have not sprouted, and show no signs of greening or rot to minimize health risks.
How can you identify if a potato is old or contaminated?
Identifying old or contaminated potatoes is critical to avoiding disease. Visible signs of aging or contamination include sprouting, green skin, soft spots, mold, or an off smell. Potatoes that have begun to sprout or have green skin may contain higher levels of solanine and should be avoided. Similarly, any potato with visible mold or a sour smell is likely contaminated with fungi or bacteria and should be discarded. The skin of fresh potatoes is typically smooth and firm, so any potato with wrinkled or soft skin should be suspected of being old.
Regular inspection of stored potatoes is also advisable, as potatoes can deteriorate over time. Checking for any signs of moisture, which can accelerate rot and the growth of pathogens, is crucial. Potatoes should be stored in a cool, dark place with good ventilation to slow down the aging process. Before purchasing potatoes, especially from markets or farms, it’s a good idea to inspect them carefully for any signs of damage or aging. By being vigilant and choosing potatoes wisely, consumers can significantly reduce the risk of disease associated with eating old potatoes.
What should you do if you suspect you have eaten an old potato and feel unwell?
If you suspect you have eaten an old potato and are feeling unwell, it’s essential to monitor your symptoms closely and seek medical attention if they worsen or if you experience severe symptoms such as difficulty breathing, severe abdominal pain, or signs of neurological impairment. Mild symptoms like nausea or diarrhea might resolve on their own, but it’s always better to err on the side of caution, especially if you’re unsure about the potato’s quality or if you have a weakened immune system.
In cases where solanine poisoning is suspected, medical professionals may administer treatments aimed at managing symptoms and supporting the body’s functions until the toxin is cleared. This can include hydration, medication for nausea or vomiting, and in severe cases, hospitalization for close monitoring and treatment. It’s also a good idea to report the incident to your local health department, especially if the potato was purchased from a store or restaurant, to help prevent others from getting sick. Prompt action and seeking medical advice can help mitigate the effects of eating an old potato and ensure the best possible outcome.
