You shouldn’t eat the sprouts because they contain solanine, chaconine, and other toxic glycoalkaloids. These compounds can have serious side effects, including neurological and digestive symptoms like headaches, vomiting, and diarrhea ( 6 , 7, 8 , 9 ).
Is it safe to eat sprouted potatoes?
Ultimately, the best way to protect yourself is to toss out potatoes containing green patches or sprouting. However, if you do notice sprouting or a green tint in some areas, you can try and remove them with a sharp paring knife and still cook with the rest of the potato (although this isn’t recommended).
Can you get sick from eating sprouting potatoes?
Large sprouts, growths, and roots will not only be unpleasant to eat, but, in the worst cases, can also make you really sick. Symptoms of poisoning from solanine (the specific type of those harmful compounds found in spoiled potatoes) include everything from a fever and headache to a severely upset stomach.
How long can solanine poisoning last?
Symptoms may last for 1 to 3 days, and hospitalization may be necessary. Death has been reported, but is rare. DO NOT touch or eat any plant with which you are not familiar. Wash your hands after working in the garden or walking in the woods.
When should you not eat potatoes?

How much solanine is toxic?
It is suggested that doses of 200–400 mg for adult humans can cause toxic symptoms (20–40 mg for children). Most commercial potatoes have a solanine content of less than 0.2 mg g−1. However, potatoes that have been exposed to light and have started to turn green can show higher concentrations.
What does solanine smell like?

CONSTITUTION: Solanin is removed from potatoes by dipping the potatoes in vinegar of 30-60 deg. C, containing 0.3-1.0 vol% of acetic acid, for 2-5 minutes.
How do you test for solanine?
The evaluation of solanine was done by standard chemical tests. The later process performed was thin layer chromatography which was performed by using chloroform: Menthol: Ammonia (7:3:0.5) solvent system for the analysis of glycoalkaloid solanin. IR graph of solanine resembling various peaks was obtained.
Can you cook sprouted potatoes?
Green spots and sprouts contain more toxins than the potato itself, according to Kim. “These toxins cannot be destroyed by cooking but eliminated by removing” the green or sprouted portions before cooking, Kim says. Keep in mind that you would have to consume large amounts of these toxins to experience ill effects.

How do I know if my potatoes have solanine?
If potatoes aren’t stored properly and have been exposed to light then they will often turn green due to the production of chlorophyll. If they are green this will also be an indicator of an increase of toxins, like solanine, in the potato.

Specifically, the color green. The presence of chlorophyll in a potato means that a glycoalkaloid poison named solanine is also present.
Is it OK to cut mold off potatoes?
Fruits and vegetables, FIRM
Cut off at least 1 inch around and below the mold spot (keep the knife out of the mold itself so it will not cross-contaminate other parts of the produce). Small mold spots can be cut off FIRM fruits and vegetables with low moisture content. It’s difficult for mold to penetrate dense foods.
How common is botulism in potatoes?
Cases of botulism from foil-wrapped baked potatoes are rare, but they do occur. One example occurred in El Paso, TX, in 1994, the largest botulism outbreak since 1978.
What type of poisoning is solanine?
Solanine is a toxic glycoalkaloid known to accumulate under certain conditions in potato plant, sprouts and tuber in levels which, if ingested, may cause poisoning in humans and farm animals.
How much raw potato is poisonous?
The normal amount of solanine in a potato’s peel means a 200-pound person would have to eat 20 pounds of potatoes to experience a toxic level, according to the University of Nebraska. However, exposure to light can increase solanine levels up to 10 times.
