Can I cook potatoes that have been halved and then wrapped in foil and left on the countertop for 8-10 hours on a hot summer day?
No! We receive many similar questions about prepared potatoes, asking if they are safe when left out of the safe temperature holding zones (‘safe’ is cooked potatoes either held at 140 degrees F serving temperature after preparation - OR prepared potatoes, cooked then allowed to cool briefly and then held in refrigeration) . Wrapped or otherwise, if cooked potatoes are left at room temperature for longer than two hours then discard and do not consume. Food safety is imperative, so it’s always best to err on the side of caution.

Established in 1937, the Idaho Potato Commission (IPC) is a state agency that is responsible for promoting and protecting the famous "Grown in Idaho®" seal, a federally registered trademark that assures consumers they are purchasing genuine, top-quality Idaho® potatoes. Idaho's ideal growing conditions, including rich, volcanic soil, climate and irrigation differentiate Idaho® potatoes from potatoes grown in other states.
