Opened prunes last 1 month in the pantry and 6 months in the fridge. Unopened, they keep 6 months in the pantry.
USDA FoodKeeper has no separate entry for prunes. It is covered by “Fruits, dried (raisins, apricots, mangoes, cranberries, etc.)” (dried fruit), so this page uses that entry’s storage times.

About prunes
Prunes belong to our pantry staples category. USDA FoodKeeper has no separate entry for prunes. It is covered by “Fruits, dried (raisins, apricots, mangoes, cranberries, etc.)” (dried fruit), so this page uses that entry’s storage times. According to USDA FoodKeeper, they keep 6 months in the fridge and 1 month in the pantry. They are not a high-risk perishable food, so the main concern is quality rather than safety. Where to keep them: ready-to-eat and cooked food goes on the upper shelves, above anything raw.
Dry pantry staples last a long time because microbes need water to grow. Their enemies are moisture, heat, light, air and pantry pests. Most of them do not become unsafe after their best-by date; they slowly lose flavour, aroma and texture. Whole-grain products and anything containing natural oils are the exception, because those oils can go rancid.
Prunes storage times by method
| Method | Duration | Temperature | Container | Notes |
|---|---|---|---|---|
| Pantry / counter (opened) | 1 month | 68–72°F | Airtight, dry | cool, dry place |
| Refrigerator (opened) | 6 months | ≤ 40°F / 4°C | Airtight, dry | at or below 40°F (4°C) |
| Pantry / counter (unopened) | 6 months | 68–72°F | Airtight, dry | cool, dry place |

Prunes shelf life, answered
How long do prunes last in the fridge?
6 months at 4°C (40°F) or colder (opened). Keep it sealed so it does not pick up moisture or odours.
How long do prunes last in the freezer?
Not listed. FoodKeeper gives no freezer time for prunes.
How long do prunes last at room temperature?
1 month in a cool, dry place.
How long do prunes last after opening?
6 months in the fridge, or 1 month in the pantry once opened. The printed date stops applying the moment you break the seal.
How long do unopened prunes last?
6 months in the pantry, if the seal is intact and it is stored as the label says.
How long is prunes good for past the expiration date?
FoodKeeper gives unopened prunes 6 months in the pantry, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
How can you tell if prunes are bad?
Musty, sour or rancid odour. Clumping from moisture, or a damp feel. Webbing, holes, or tiny insects in the bag.
Signs prunes have gone bad
Smell
Musty, sour or rancid odour.
Texture
Clumping from moisture, or a damp feel.
Pests
Webbing, holes, or tiny insects in the bag.
Flavour
Flat, stale or bitter taste — quality is gone even if it is safe.
Nothing ticked? Good sign. Still check how long it has been stored: the bacteria that cause food poisoning are invisible.
Any of these means it has gone bad. Throw it out — don't taste it to check.
Why prunes go bad
In dry foods, quality declines through oxidation and moisture rather than bacteria. Oils in whole grains, nuts and seeds slowly oxidise and turn rancid, giving a bitter, paint-like smell. Moisture lets mould grow and makes powders clump, and warm storage invites pantry moths and beetles.
Common prunes storage mistakes
- Storing it above the stove, kettle or dishwasher, where heat and steam speed spoilage.
- Leaving bags open instead of transferring to airtight containers.
- Mixing new stock into old so the oldest never gets used.
- Scooping with a damp spoon.
Can you freeze prunes?
- 1Step 1
Freezing is optional for dry goods; it mainly stops pests and rancidity.
- 2Step 2
Use an airtight container or a well-sealed freezer bag.
- 3Step 3
Let it come to room temperature before opening to avoid condensation.
Prunes left out overnight
Prunes are shelf-stable until opened. A night on the counter is fine — keep them cool, dry and away from sunlight.
Best-by and use-by dates on prunes
Unopened
FoodKeeper gives unopened prunes 6 months in the pantry, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
Opened
Once opened, the printed date no longer applies. Count 6 months in the fridge or 1 month in the pantry from the day you open it.
How to store prunes
- Store in an airtight container in a cool, dark, dry place.
- Keep away from the stove and dishwasher, where heat and humidity speed spoilage.
- Write the opening date on the pack.
How to pick fresh prunes
- Check packages for holes, webbing or clumping.
- Buy whole-grain flours and nuts in quantities you will use within a few months.
- Look for the latest best-by date.
Prunes: use them up in time
- Keep older stock at the front so it is used first.
- Freeze whole-grain flours and nuts to stop rancidity.
- Plan a 'pantry week' of meals built around what you already have.

True or false? Prunes myths
- Correct!Not quite.
Partly true. Prunes are not high-risk, so a little past 6 months usually means lower quality, not danger. Check for mould and off smells first.
- Correct!Not quite.
False. Freezing pauses bacteria; it does not kill them. They become active again as the food thaws, so thaw in the fridge and cook or reheat properly.
- Correct!Not quite.
Only partly. FoodKeeper gives no freezer time for prunes.
- Correct!Not quite.
False. The door warms up every time it opens. Ready-to-eat and cooked food goes on the upper shelves, above anything raw.
- Correct!Not quite.
False. Prunes are shelf-stable: 1 month in a cool, dry place. Refrigerating can extend quality for some foods, but it is not needed for safety.
