Homemade beef jerky that is properly dried and sealed keeps for about two weeks at room temperature. Put it in the refrigerator and it lasts for months, and the freezer is the place for anything you want to keep longer. Store-bought jerky is a different story, because it is made to sit on a shelf until the date printed on the package. This guide covers how long beef jerky lasts in each situation, how to store it, and how to tell when it has gone bad.
Homemade jerky: up to 2 weeks in a sealed container at room temperature, 3-6 months in the refrigerator.
Store-bought jerky: follow the “best by” date on the package while it is sealed, then treat it like homemade once you open it.
Longest storage: freeze it in airtight bags with the air pressed out.
Shelf Life at a Glance
These times come from the National Center for Home Food Preservation and Ohio State University Extension, and they assume the jerky was heated to a safe temperature and dried until it cracks without snapping.
| Where It Is Stored | Homemade Jerky | Notes |
|---|---|---|
| Room temperature | Up to 2 weeks | Sealed container, cool and dry spot |
| Refrigerator | 3-6 months | Airtight bag, jar or vacuum-sealed pouch |
| Freezer | Longest option | Best quality within a few months; no set limit from the extension guides |
The National Center for Home Food Preservation says properly dried jerky keeps at room temperature for two weeks in a sealed container, and that refrigerating or freezing it extends shelf life and preserves flavor. Ohio State’s jerky factsheet gives the refrigerator range as three to six months.
Does Beef Jerky Go Bad?
Yes. Drying slows spoilage but does not stop it. Jerky goes bad when it is not dry enough, when it is stored warm or humid, or when the fat in it turns rancid. Throw it out if you notice any of these:
- Mold: fuzzy or powdery spots that are white, green, gray or black.
- A sour, musty or rancid smell: fresh jerky smells meaty and seasoned, not sharp or oily.
- A slimy or sticky surface: that means moisture is back in the meat.
- An unusually soft texture: dry jerky bends and cracks, it does not feel damp or squishy.
Salt can crystallize on the surface and fat can form a whitish film, and neither is harmful. Mold looks fuzzy and grows in patches. If you cannot tell the difference, discard the jerky.
Fat is the main reason jerky goes off early. NCHFP tells home jerky makers to trim and discard all fat before drying because fat “becomes rancid quickly.” If your jerky spoils sooner than the times above, look at your trimming first.

Does Beef Jerky Need to Be Refrigerated?
It depends on where the jerky came from:
- Unopened store-bought jerky is made to be shelf-stable, so it does not need the refrigerator. Check the date on the package.
- Opened store-bought jerky keeps best in a resealed bag or container. Follow the storage instructions on the package, and refrigerate it if you will not finish it within a couple of weeks.
- Homemade jerky has no preservatives or oxygen-absorbing packets, so refrigerate or freeze whatever you will not eat within about two weeks.
How to Store Homemade Jerky
- Let it cool completely. Warm jerky sealed in a bag sweats, and that moisture is what grows mold. Give it 30 minutes or more on a rack.
- Blot any grease. Press the pieces between paper towels so surface fat does not pool in the container.
- Check for dryness. Bend a piece. It should crack without snapping in two. If it is still soft, put it back in the dehydrator. Our beef jerky temperature and time chart shows drying times by thickness.
- Pack it airtight. Ohio State lists zipper bags, glass jars and vacuum-sealed containers as good options. Press the air out of bags.
- Keep it cool and dry. A pantry shelf works for the two-week window. For anything longer, use the refrigerator.
- Label it. Write the date on the bag so you know when the two weeks are up.

Why Homemade Lasts Less Than Store-Bought
Commercial jerky is made under controlled conditions, dried to a set moisture level and sealed in packaging built to keep air out, often with an oxygen absorber. At home you are working with a kitchen dehydrator, a knife and a zipper bag, so the margin is smaller. Three things make the biggest difference:
- The heating step. The USDA recommends heating meat to 160°F (165°F for poultry) before or after drying, because drying alone does not reliably kill bacteria. Our step-by-step jerky guide shows the safe way to do it.
- How dry it gets. Thicker strips and humid days leave more moisture behind. See how long to dehydrate jerky.
- How much fat is left. Lean cuts last longer.
Freezing and Thawing
The freezer is the right answer for a big batch. Divide the jerky into portions you can finish in a couple of weeks, press the air out of freezer bags (or vacuum seal them) and date them. Thaw a portion in the refrigerator overnight, then keep it sealed and eat it within the room-temperature window. Avoid repeated thawing and refreezing, which draws moisture into the meat.
Quick Answers
Can homemade jerky last a year?
Not in the pantry. Frozen jerky can be safe for a long time, but quality drops, so plan on eating it within several months for the best flavor.
Is jerky safe after the best-by date?
A best-by date is about quality, not safety. If the package is intact and the jerky smells and looks normal, it is usually fine. If anything seems off, throw it away.
Why is my jerky moldy after a few days?
Almost always because it was sealed while warm or was not dried enough. Cool it fully, dry it until it cracks when bent, and store it in the refrigerator if you are unsure.
Does vacuum sealing help?
Yes. Removing air slows rancidity and mold. Ohio State lists vacuum-sealed containers among the good packaging choices. Vacuum sealing is not a substitute for refrigeration with homemade jerky.
