For potatoes, the official window only makes sense when you pair it with how the item was actually stored, handled, and served at home. Warm exposure, repeated opening, contamination, and missing open dates can matter just as much as the printed date.

Signs potatoes should be discarded or replaced

When to set a reminder in ShelfDate
- Set one reminder 30 days before the printed date.
- Set another reminder on the day you open it.
- Use a shorter reminder anchored to the FoodKeeper after-opening window if one is listed.
- Add a one-off reminder if the item is left warm or the fridge loses power.
