Green potatoes can give you stomach problems – news Oslo og Viken – Local news, TV and radio

Potato farmer Sven Nesset holds a green potato in his hand. It contains the toxin solanine, which can make you sick. – You will in any case have stomach problems, discomfort and a bad experience, says Nesset. The farmer from Ørje in Østfold believes that Norwegian stores do not take good enough care of the potatoes. – They are put out in non-covering boxes, preferably also in lamplight and with a high temperature in the room. It is the potato’s worst enemy for losing quality. Potatoes should be in a bag, preferably dark and slightly cool, he says.

Communications manager for group, finance and sustainability in Norgesgruppen, Ingrid Solberg Gundersen, says high circulation speed and good operations are the best measures to avoid green potatoes. – We have carried out research projects to gain more knowledge about the effect of various solutions.

That’s what senior advisor in the chemical food safety section at the Norwegian Food Safety Authority, Cecilie Svenning, says. – Green potatoes and sprouting potatoes contain more solanine, both the chlorophyll and the solanine are usually just under the skin. Intake of large amounts of solanine can cause poisoning, she says. Cecilie Svenning, senior advisor in the chemical food safety section at the Norwegian Food Safety Authority.

If you peel away the green on the potatoes before you cook the potatoes, 90 per cent of the solanine will also disappear, says Svenning.
