Saudi Arabia: Warning about toxic types of potatoes spread in vegetable markets, and an expert explains how to differentiate them from healthy potatoes

The specialist warned Fahd Al-Saeed Avoid eating potatoes that have green spots on them, indicating that this is a sign of the presence of a toxic compound known as “solanine.” This compound occurs naturally in potatoes as a defense mechanism against fungi and insects, but it may pose a threat to human health when consumed in large quantities.

Al-Saeed explained that solanine is mainly concentrated in potato peels and sprouts, indicating that exposure to light stimulates its production. Therefore, it is recommended to avoid buying potatoes that appear to have any green spots, even if they are minor, and to make sure to store them in a dark, dry place to prevent the formation of this compound.

Al-Saeed pointed out that peeling potatoes and removing the sprouts helps get rid of 30 to 80% of solanine, stressing the need to avoid eating green potatoes completely, especially by children and the elderly, as they are more susceptible to its toxicity.

He added that the symptoms of solanine poisoning range from nausea, vomiting, diarrhea, and abdominal pain, and in severe cases, they may lead to nervous system disorders such as headache, dizziness, and hallucinations. In rare cases, poisoning may lead to coma or even death.

Al-Saeed called on consumers to ensure that they buy potatoes from reliable sources and handle them in a proper manner to maintain their safety and avoid the risks of food poisoning.
