Jerky is a go-to snack for adventurers, athletes, and snackers alike. It’s lean, flavorful, protein-packed, and shelf-stable - which makes it ideal for hiking trips, gym bags, office drawers, and emergency kits. But even though jerky is preserved through drying and seasoning, it doesn’t last forever.
From beef and deer jerky to premium fish jerky storage matters. In this article, we’ll walk you through how long jerky lasts, whether it can go bad, and how to keep your jerky fresh for the long haul - especially after opening.
What’s the best way to store jerky after opening?
Once you open a bag of jerky, exposure to air and moisture becomes the biggest threat to its freshness. The best way to store opened jerky is to keep it in an airtight container or tightly resealed in its original packaging. A zip-top bag, vacuum-sealed pouch, or even a glass jar with a tight-fitting lid can work well.
If you plan to eat the jerky within a few days, keeping it at room temperature in a cool, dry spot is fine. However, if you’re unsure how soon you’ll finish it, storing it in the refrigerator helps maintain texture and flavor. For long-term storage, especially for larger quantities or homemade batches, freezing is ideal.
Should I refrigerate jerky after opening?
Yes, refrigeration is a smart choice after opening jerky - especially if you don’t plan to finish it within a couple of days. While jerky is shelf-stable due to its low moisture content, once the seal is broken, it can begin absorbing moisture from the environment, increasing the risk of spoilage.
Refrigerating your jerky can extend its freshness up to 1–2 weeks. Be sure to use an airtight container to prevent it from drying out or absorbing odors from other foods. This method works well for jerky which contain fewer preservatives.
Can I freeze jerky to make it last longer?
Absolutely. Freezing jerky is one of the most effective ways to preserve it for long-term storage, especially if you’ve purchased in bulk or made it at home. When stored in a freezer-safe, airtight container or vacuum-sealed bag, jerky can maintain its quality for up to 6 months or longer.
To defrost, move the jerky to the refrigerator and let it thaw slowly to avoid condensation. Avoid refreezing once thawed, as it can negatively affect the texture. Whether it’s beef, deer, or wild-caught fish jerky freezing is a simple way to keep your stash fresh for future snacking.
How long does opened jerky last at room temperature?
Once opened, jerky stored at room temperature generally stays fresh for about 3 to 5 days, depending on the humidity and temperature of your environment. If stored in a cool, dry place in an airtight container, it may last slightly longer, but flavor and texture will begin to degrade over time.
To maximize shelf life, always reseal the package tightly and avoid repeated exposure to air. In hot or humid conditions, jerky can spoil faster, so refrigeration is a safer bet. If you notice any unusual smell, stickiness, or mold, it’s best to throw it out.
Can homemade jerky be stored without refrigeration?
Yes, but with caution. Homemade jerky can be stored at room temperature for up to 1–2 weeks, provided it’s been thoroughly dried and stored in an airtight container. However, since homemade jerky typically lacks preservatives and vacuum sealing, it’s more susceptible to moisture and bacteria.
For best results, refrigerate or freeze homemade jerky - especially if you're storing large batches or live in a humid climate. These extra precautions will help maintain quality and reduce any risk of spoilage, while still letting you enjoy your jerky whenever you want.
Does jerky go bad?
Yes, jerky can go bad over time, especially if it’s not stored properly. Although jerky is a preserved meat product, it’s still a food that can spoil when exposed to air, heat, or moisture. Over time, even the best-sealed jerky can develop mold, go rancid, or lose its flavor and texture if the packaging is damaged or the jerky is past its shelf life.
You’ll know jerky has gone bad if it smells sour, has visible mold, or feels unusually soft, sticky, or slimy. At that point, it’s best to toss it. Eating spoiled jerky can lead to foodborne illness. If you're ever in doubt, check the expiration date and trust your senses - smell, look, and feel are your best tools.
How long does beef jerky last?
Unopened beef jerky from reputable brands typically lasts up to 12 months from the packaging date, depending on how it’s processed and sealed. Most store-bought jerky is vacuum-sealed and contains preservatives that help extend shelf life. Just be sure to store it in a cool, dry place, away from direct sunlight.
Once opened, jerky’s shelf life drops significantly. If you’re not eating it all at once, make sure to reseal the bag tightly or transfer the jerky into an airtight container. Without refrigeration, opened beef jerky is best consumed within 3 to 5 days. If you store it in the refrigerator, it may last up to 2 weeks with proper sealing.
Do beef jerky expire?
Yes, even the driest jerky will eventually expire. Store-bought jerky will always have a “Best By” or expiration date on the package typically 6 to 24 months from manufacture. While jerky doesn’t “rot” as quickly as fresh meat, over time the fat content in the meat can go rancid, and the texture and taste will deteriorate.
That said, expiration dates are based on optimal freshness, not food safety alone. If you’re past the date and the jerky has been stored well (unopened, cool environment), it might still be safe to eat - but it likely won’t taste as good. If the jerky smells off or looks suspicious, don’t risk it.
How long does homemade jerky last?
Homemade jerky doesn’t last as long as commercial varieties because it often lacks preservatives and vacuum sealing. If you store it in an airtight container at room temperature, it typically lasts 1 to 2 weeks. For longer storage, refrigeration or freezing is necessary.
To extend the shelf life of homemade jerky, you can store it in the refrigerator for up to 1 month, or freeze it for up to 6 months. Be sure the jerky is completely dehydrated and cooled before packaging. Also consider using vacuum sealers or oxygen absorbers for added longevity.
Can you freeze beef jerky?
Yes - you can absolutely freeze beef jerky. Freezing is one of the most effective ways to preserve jerky, especially if you’ve made it yourself or purchased in bulk. When frozen properly in an airtight or vacuum-sealed bag, jerky can maintain its flavor and texture for up to 6 months or more.
When you’re ready to eat it, simply move the jerky to the refrigerator to thaw slowly. Avoid defrosting it at room temperature, as condensation can introduce unwanted moisture. Once thawed, consume the jerky within a few days for the best experience.
Can jerky be frozen?
Yes, jerky of all types - beef, fish, venison can be frozen. This is especially helpful for homemade jerky that hasn’t been vacuum-sealed or contains no preservatives. Freezing prevents microbial growth and oxidation, extending the jerky’s safe lifespan without sacrificing taste.
Make sure to use freezer-safe bags or containers, removing as much air as possible. You can even toss in a desiccant or oxygen absorber for extra protection. Just remember to label the packaging with the date you froze it so you can track freshness.
Does jerky need to be refrigerated?
Jerky doesn’t need to be refrigerated if it’s unopened and stored in a cool, dry place. That’s part of what makes it so convenient. However, once the package is open, you should refrigerate it if you won’t finish it within a few days.
Refrigeration is especially important for homemade jerky, which may not contain preservatives. Storing it in the fridge in an airtight container can extend its freshness for up to two weeks. For ultimate freshness, vacuum-sealing your jerky - whether store-bought or homemade - will significantly help.
How to store beef jerky for maximum freshness
To keep beef jerky fresh and tasty, it’s all about limiting exposure to air and moisture. Store unopened jerky in a pantry, drawer, or dry cabinet - away from heat or light. Once opened, reseal the bag tightly or move the jerky to an airtight container or vacuum-sealed pouch.
You can also store jerky in the fridge to slow down oxidation, especially if you live in a humid climate. If you're not planning to eat it soon, freezing is your best bet. Always check for mold or off smells before eating opened or older jerky.
How to store deer jerky?
Deer jerky follows the same storage rules as beef or fish jerky. Unopened and vacuum-sealed, it will last for several months in a cool pantry. After opening, deer jerky should be stored in the refrigerator and consumed within a week or so, or frozen for longer shelf life.
Because deer jerky tends to be lean and gamey, it can dry out or spoil faster if not properly sealed. Use resealable bags, vacuum packaging, or mason jars with airtight lids to preserve flavor and texture. If freezing, portion it out to avoid thawing and refreezing repeatedly.
What is the best way to keep jerky fresh?
The best way to keep jerky fresh is a combination of smart packaging and smart storage. Whether it’s fish jerky from Kaimana or your own homemade batch, keep it in an airtight, moisture-proof container, store it in a cool, dark place, and consume within the recommended time window.
For longer-term storage, use vacuum-sealed bags with desiccants or freeze portions you’re not planning to eat right away. Always check for signs of spoilage before snacking. Proper jerky care keeps the flavor bold and the protein punch intact.
How do you know if jerky has gone bad?
Spoiled jerky is usually easy to spot once you know what to look for. The most obvious signs include visible mold, discoloration, and an off smell - think sour, rancid, or musty aromas. If the jerky feels sticky, slimy, or oddly soft (instead of dry and chewy), that’s a big red flag. Also, if it tastes bitter, overly metallic, or just “off,” it’s safest to toss it.
While jerky is designed to be shelf-stable, it’s still a meat product and can deteriorate if exposed to heat, moisture, or oxygen. If your jerky has been opened for a while, especially without being refrigerated or resealed properly, spoilage can happen fast. Trust your senses - and when in doubt, don’t risk it.
What happens if you eat expired jerky?
Eating expired jerky isn't always dangerous, but it can be risky, especially if it’s been stored improperly. If the jerky was well-sealed and only a few weeks past its date, it may still be edible - though the texture and taste might be off. However, if mold is visible or the jerky smells sour, eating it could lead to stomach issues, including food poisoning.
Jerky made without preservatives (like many homemade versions) carries a higher spoilage risk. If it's expired and shows signs of bacterial growth, you might experience nausea, vomiting, or worse. Always check the expiration date, inspect the jerky, and use caution especially with kids, pregnant individuals, or those with weaker immune systems.
Can you eat jerky left out overnight?
If your jerky was left out overnight unopened and sealed, it’s likely just fine. Jerky is designed to be shelf-stable and doesn’t require refrigeration until opened. However, if the bag was already opened and left exposed to air, temperature, or humidity for several hours, it may have started to degrade.
In a cool, dry room, exposed jerky might still be safe the next morning. But if it was left out in a hot car, humid tent, or direct sunlight, bacteria and mold could have started to grow. When in doubt, check for off smells, stickiness, or changes in color or texture. Jerky is hardy, but not invincible.
How to tell if jerky is still good after opening?
After opening a pack of jerky, freshness depends on both storage conditions and elapsed time. If the jerky is still dry, chewy, and smells fresh (smoky, savory, or seasoned), it’s likely still good. Resealable packaging, cool storage, and limited exposure to air all help preserve freshness after opening.
On the other hand, if it has become soft, sticky, or overly hard and brittle, or if it smells sour or odd, it's time to throw it away. If you know you won’t eat it within a few days, refrigerating or freezing opened jerky can extend its shelf life and protect it from spoilage.
Is vacuum-sealed jerky shelf-stable?
Yes, vacuum-sealed jerky is typically very shelf-stable. Removing oxygen from the packaging significantly slows the growth of bacteria and mold. Still, shelf life depends on the quality of the seal, storage temperature, and whether preservatives are used. Once you open a vacuum-sealed package, treat it like any other jerky - consume it within a few days, or refrigerate to prolong freshness. For long-term storage, freezing sealed packs is a great option.
Does jerky go bad if not refrigerated after opening?
Yes, if jerky is left open at room temperature for too long, it can go bad- even if it was originally shelf-stable. Without refrigeration, opened jerky is vulnerable to moisture, air exposure, and bacterial growth, especially in warmer climates or high-humidity environments.
To keep jerky safe and tasty after opening, either reseal the original packaging tightly, use an airtight container, or refrigerate it. For maximum freshness, eat opened jerky within 3 to 5 days at room temperature or refrigerate to stretch that to 1–2 weeks.
