FoodKeeper-based refrigerated planning reference
How long do bananas last in the fridge?
Well Stockd’s curated reference uses about 5 days refrigerated for bananas, assuming a refrigerator kept at 40°F (4°C) or below. This is a planning estimate drawn from the app’s FoodKeeper/FSIS-based catalog, not a package date or a safety guarantee.
Unopened, opened, and frozen
The single fridge number above is a planning figure. Most of the questions people actually ask about bananas turn on whether the package has been opened, so those windows are listed separately here.
- Unopened
- Ripen on the counter in 2 to 5 days; once ripe, the fridge holds them 5 to 7 more days, though the peel blackens
- Opened or cut
- Peeled or cut banana browns within an hour; toss with lemon juice and eat the same day
- Freezer
- About 90 days at best quality. Frozen food stays safe indefinitely at 0°F; the window is about texture and flavour.
- How to store it
- Counter until ripe, away from other fruit unless you want to speed those up — bananas give off a lot of ethylene. Refrigerate only once ripe; cold stops the ripening for good. Peel and freeze in chunks for smoothies and banana bread.
How to tell if bananas has gone bad
Dates are estimates; these are the checks that actually decide it. When more than one of these is present, throw it out rather than tasting to find out.
- Mushy, weeping flesh under the peel
- Fermented or alcoholic smell
- Mould at the stem
- Fruit flies gathering on the bunch
How to use this window
A weekly kitchen review is frequent enough to surface this item before the catalog window passes.
Well Stockd does not know when this food was harvested, packed, purchased, opened, prepared, or moved between storage locations. Record the relevant opened, prepared, or refrigerated date, follow package directions, keep your refrigerator at 40°F or below, and use the official item listing when food safety is in question.
Primary sources and limits
The repository catalog identifies USDA FoodKeeper and FSIS typical refrigerated storage guidance as its source. FoodKeeper explains that storage times are guidelines and that actual quality varies with growing, handling, distribution, and storage conditions.
