Still within the safe window, but only just. Eat it today or move it to the freezer now.
Beyond the recommended fridge time. Throw it away, however normal it looks or smells.

Days count from when it was bought, opened or cooked, assuming a fridge set to 4 °C (40 °F) or below.
Test the timing on your pickled herring
Well within the 2-hour limit. Get it into the fridge right away, spread out in a shallow dish so it chills fast.
OK at ordinary room temperature. If it is hotter than 32°C (90°F), though, the limit shrinks to just 1 hour, so get it into the fridge at once.
The USDA cut-off is two hours. If the room was warm, or you can't say for certain how long it has been, throw it out.
This is over the 2-hour limit, and bacteria could have grown, or made toxins that a round of reheating won't destroy.
Pickled herring left out overnight has sat for hours on end between 4°C and 60°C (40–140°F), the danger zone. Appearance is no guide here: it isn't safe to eat.
Anything warmer than 4°C (40°F) counts as room temperature. When it's hotter than 32°C (90°F), the limit drops to 1 hour.
How long pickled herring keeps with each storage method
| Storage | How long | Temp | Packaging | Good to know |
|---|---|---|---|---|
| Counter / pantry | 2 hours | 68–72°F | Airtight | only 1 hour above 90°F |
| Refrigerator | 4–6 months | ≤ 40°F / 4°C | Airtight | 40°F (4°C) or colder |
| Freezer | Not recommended | 0°F / -18°C | Wrapped or freezer bag | hurts texture or safety |
Getting to know pickled herring
Pickled herring sits in the seafood section of our food guide. The USDA FoodKeeper database files it under the name “Herring (glass packed, in wine sauce)”. Going by USDA FoodKeeper, it lasts 4–6 months in the fridge. Freezing is not advised. As with any perishable food, it shouldn't spend more than 2 hours at room temperature. Best storage spot: cooked and ready-to-eat food sits on the upper shelves, higher than anything raw.
Smoked, cured and processed meats keep longer than fresh cuts because salt, smoke, nitrites and reduced moisture all hold bacteria back. That does not make them shelf-stable. Opening the package lets in air and handling, which starts the countdown, and sliced products go off sooner than whole pieces since so much more of their surface is exposed.

Your pickled herring storage questions
How long does pickled herring last in the fridge?
4–6 months when held at 4°C (40°F) or below. Start counting on the day it was bought, opened or cooked.
How long does pickled herring last in the freezer?
Not recommended. FoodKeeper advises against freezing pickled herring: the texture falls apart, or the thawed result can't be trusted to be safe.
How long does pickled herring last at room temperature?
2 hours at most, or 1 hour if the air is above 32°C (90°F). Throw out perishable food that has been out longer than that.
How long is pickled herring good after the expiration date?
With perishable pickled herring, time in storage counts for more than whatever the label says. Once it has spent longer than 4–6 months in the fridge, throw it out — even if the printed date hasn't arrived yet.
How do you know if pickled herring is bad?
A rancid or sour odor where it should smell salty or smoky. A slippery, slimy film coating the links or slices. Patches of gray, green or a rainbow-like sheen that keep spreading.
How long can pickled herring sit out?
At room temperature the limit is 2 hours, dropping to 1 hour when the temperature tops 32°C (90°F). A whole night out is never safe.
How to spot spoiled pickled herring
Odor
A rancid or sour odor where it should smell salty or smoky.
Texture
A slippery, slimy film coating the links or slices.
Color
Patches of gray, green or a rainbow-like sheen that keep spreading.
Mold
Fuzzy growth on sliced or cooked cured meat means the package should be thrown out.
No boxes ticked? That's encouraging. Even so, confirm how long it has been stored, because the germs behind food poisoning can't be seen with the naked eye.
Even one of these means it has spoiled. Toss it, and never taste it to find out.
What makes pickled herring spoil
Curing holds back most spoilage organisms, but Listeria monocytogenes is the exception: it can keep growing at fridge temperature on ready-to-eat products like sliced deli meat and hot dogs. This is the chief reason opened packages get such a brief window, and it explains why anyone who is pregnant, along with older adults, is advised to reheat deli meats until they are steaming hot.
Mistakes people make storing pickled herring
- Holding on to an opened package long after its opened window simply because the date on the label is weeks away.
- Leaving a platter of sliced meats sitting out for hours while guests graze.
- Putting opened packs back without rewrapping them, so they dry out and soak up other smells.
- Using one knife or cutting board for both raw meat and ready-to-eat meats.
Can you freeze pickled herring?
Reheating pickled herring the safe way
Heat to 74°C (165°F)
Push a food thermometer into the thickest part; the food should steam right through to the middle.
Just once
Warm only the portion you plan to eat. Every round of cooling and reheating hands bacteria another opening.
Cover, then stir
When microwaving, put a cover on the dish and stir it midway through to get rid of cold spots.
Frozen leftovers
Let them thaw in the refrigerator first, or heat them directly from frozen and give them more time.
Pickled herring left out overnight
Pickled herring kept out at room temperature beyond 2 hours (just 1 hour once the room tops 90°F / 32°C) should go in the trash. Bacteria grow fastest anywhere from 40°F to 140°F, and some of the toxins they leave behind survive reheating.
Bacteria grow at their fastest in the 4 °C to 60 °C (40–140 °F) range.
Keeping pickled herring in good shape
- Cured or not, it still needs refrigeration at 40°F (4°C) or colder.
- After opening, wrap it tightly again or transfer it to an airtight container.
- Stick to the opened-storage window, whatever date is printed on the package.
What the dates on pickled herring packaging mean
Best-by vs. sell-by
Counting from the purchase date, FoodKeeper allows unopened pickled herring 4–6 months in the refrigerator. Labels such as "best-by" and "sell-by" are about peak quality and how stores rotate stock, not about safety — infant formula is the one product whose use-by date federal law requires.
Past the printed date
With perishable pickled herring, time in storage counts for more than whatever the label says. Once it has spent longer than 4–6 months in the fridge, throw it out — even if the printed date hasn't arrived yet.
Choosing good pickled herring at the store
- Vacuum packs should cling tightly to the meat, with no air pockets or swelling.
- At the deli counter, order only as much as you can eat within the opened window.
- Reach for packs at the back of the case, which is the coldest part.
Pickled herring: ways to finish it in time
- If an unopened pack won't be opened before its date, move it to the freezer.
- Finish opened slices in grilled sandwiches, omelets, pasta or pizza.
- Split big packs into smaller portions and freeze whatever you won't get to soon.

Pickled herring myths: fact or fiction?
- You got it!Not this time.
False. Food-poisoning bacteria seldom alter how food smells. Keep to the 4–6 months window and discard anything older.
- You got it!Not this time.
False. The freezer puts bacteria on hold rather than killing them. They start up again as the food warms, so let it thaw in the fridge, then cook or reheat it all the way through.
- You got it!Not this time.
False. FoodKeeper advises against freezing pickled herring: the texture falls apart, or the thawed result can't be trusted to be safe.
- You got it!Not this time.
False. Each time the fridge is opened, the door heats up. Cooked and ready-to-eat food sits on the upper shelves, higher than anything raw.
- You got it!Not this time.
False. Certain bacteria produce toxins that heat cannot destroy. Reheating kills the bacteria themselves but leaves those toxins behind, so anything left out longer than 2 hours belongs in the trash.
