Potatoes that have turned green due to increased chlorophyll and photosynthesis are indicative of increased light exposure and are therefore associated with high levels of solanine. [20] Synthesis of solanine is also stimulated by mechanical injury because glycoalkaloids are synthesized at cut surfaces of potatoes. [ 18 ]
The presence of more than 20 mg/100g tuber glycoalkaloids is toxic for humans. [5] There have been instances of fatal poisoning cases from potatoes with high glycoalkaloid content. [6] However, such cases are rare. [7] Some research shows teratogenic effects on humans, but epidemiological investigations have produced conflicting research, as ...
Dirt protects the potatoes from premature spoiling, and storing moist potatoes could lead to mold Store potatoes in cool but not cold temperatures; between 45°F and 55°F is ideal.
The concentration of glycoalkaloids in wild potatoes is sufficient to produce toxic effects in humans. The toxin affects the nervous system, causing headaches, diarrhea and intense digestive disturbances, cramps, weakness and confusion, and in severe cases coma and death. Poisoning from cultivated potatoes occurs very rarely, however, as toxic ...
False, raw eggplants are not poisonous. However, the leaves and flowers of the plant can be toxic. Plants in the nightshade family -- which includes eggplants, potatoes, peppers, tomatoes and ...

Black nightshades (many species in the Solanum nigrum complex, Solanum sect. Solanum) have varying levels of toxins and are considered too toxic to eat by many people in North America and Europe, but young stems and leaves or fully ripened fruit of various species are cooked and eaten by native people in North America, Africa, and Asia.
Only good-quality seed potatoes and tomatoes obtained from certified suppliers should be planted. Often discarded potatoes from the previous season and self-sown tubers can act as sources of inoculum. [45] Compost, soil or potting medium can be heat-treated to kill oomycetes such as Phytophthora infestans. The recommended sterilisation ...
