Exposure to excessive light, especially direct sunlight, can trigger sprouting in potatoes and cause them to wrinkle and turn green. Provided they remain firm to the touch, aren’t excessively wrinkled, and the sprouts are small, potatoes are still safe to eat even after sprouting.

To prevent this, Lucia Washbrook, sales and marketing director at Branston , the UK’s largest potato supplier, has shared her expertise on proper potato storage.

Lucia claimed: “Potatoes stored in the fridge can last over three times as long compared with storing at room temperature.” This is supported by research from the Waste and Resources Action Programme, which suggests that storing potatoes in this way could potentially “save 100,000 tonnes of food waste per year”. Lucia added: “Storing potatoes in the fridge should be encouraged to prolong the lifespan and prevent Britons wasting over 5.
