The Real Truth: Does Beef Jerky Go Bad?

If you’re a fan of beef jerky, then you may have wondered if it can ever go bad. After all, the meat has been dried and cured for several days, so it seems like it would last forever. However, beef jerky eventually goes bad, although it takes longer than regular fresh meat. Learning to tell when your beef jerky has gone bad can help you avoid unpleasant surprises and ensure you always have a delicious snack.

In this article, we’ll explore does beef jerky go bad and the shelf life of beef jerky and provide tips for ensuring your snack stays fresh and tasty.

What Does The Best-By Date On Beef Jerky Indicate?

What Does The Best-By Date On Beef Jerky Indicate?

As a beef jerky enthusiast, I’ve often wondered what the best-by date on the package means. After researching the topic, here is what I found:

The best-by date on beef jerky indicates the ideal timeframe for enjoying the jerky at its freshest. Commercially packaged jerky typically has a shelf life of about one year from the best-by date. Unopened beef jerky can last 1-2 years in the pantry, even beyond the date stamped on the package, if properly sealed.

Once you open a package of jerky, its shelf life shortens. Opened packages of commercial jerky will stay fresh for about one to two weeks in the pantry or three to four weeks in the refrigerator.

Homemade jerky has a shorter shelf life compared to commercially packaged jerky. It depends on how well you package the jerky. If you vacuum-seal homemade jerky, it will last roughly one to two months in the pantry or even longer if stored in the refrigerator. Jerky from big-name companies with extra preservatives will have a longer shelf life as preservatives help preserve the jerky when exposed to air and moisture.

You can tell if jerky has gone bad by its smell, appearance, and texture. If it smells rotten, has mold, or feels unusually hard and dark, it’s best not to eat it. Eating spoiled jerky can lead to food poisoning, so it’s essential to be cautious and avoid consuming it if it smells or tastes strange.

In conclusion, the best-by date on beef jerky indicates when the jerky is at its freshest. Proper storage and following your senses can help determine if the jerky has gone bad.

Does Beef Jerky Go Bad?

Beef jerky can last long without refrigeration if stored in a cool, dry place. Commercially packaged jerky usually lasts about one year, while homemade jerky lasts 1 to 2 months. The lack of moisture in beef jerky prevents bacteria growth and extends its shelf life.

Check the best-by date and packaging for any signs of oxygen or moisture entering. Mold and rancidity indicate that the jerky has spoiled and should not be eaten. If it passes the inspection, beef jerky is safe to eat. Store it in a cool, dry place away from sunlight and heat, and keep it in its original packaging or airtight container. Freezing beef jerky is an option, but it might affect the taste and texture.

What Are The Main Factors That Contribute To Beef Jerky Spoilage?

What Are The Main Factors That Contribute To Beef Jerky Spoilage

I’ve learned that several factors can contribute to beef jerky spoilage. Here are the main ones:

  1. Environmental factors: Humidity, temperature, and air exposure play a significant role in beef jerky spoilage. The jerky becomes more susceptible to mold growth if stored in a humid environment. High temperatures can cause fats in the jerky to go rancid, resulting in an unpleasant taste and smell.
  2. Quality of ingredients: The quality of the meat used in the jerky can affect its shelf life. High-quality, lean cuts of meat generally last longer than lower-quality meats. Additionally, the production methods and preservation techniques, such as curing and smoking, can help extend the shelf life of beef jerky.
  3. Improper storage: If beef jerky is not stored correctly, it can spoil faster. Keeping jerky in a cool, dry place away from direct sunlight is essential. Proper packaging, such as vacuum-sealed bags or airtight containers, can also help minimize exposure to air and moisture.

To prevent beef jerky spoilage, buying from reputable sources, looking for freshness indicators, and consuming the jerky within a reasonable time is crucial.

Beef jerky can last different amounts of time once opened, depending on how you store it and what type of jerky it is. Here are some important things to know:

  1. How to store it: If your beef jerky comes in a resealable bag, seal it tightly after each use. If it doesn’t, transfer it to an airtight container to keep it fresh. It’s best to store it in a cool, dry place away from moisture and strong smells.
  2. Moist vs. dry jerky: If your jerky is moist, it should be eaten within 3 days if not refrigerated. Dry jerky can last up to three weeks in the fridge or two months in the freezer. But over time, the quality may not be as good.
  3. Signs of spoilage: Even if the jerky is within its recommended shelf life, check for mold or a spoiled smell before eating it. If you see any signs, don’t eat it.
  4. Homemade vs. store-bought: Homemade jerky doesn’t last as long as store-bought jerky. If properly sealed, homemade jerky can last 1-2 months. But if not sealed well, it should be eaten within a week. If refrigerated, it can last 2-3 weeks.

How Long Does Beef Jerky Last If Unopened?

Properly sealed beef jerky can last 1-2 years in the pantry, even beyond the date stamped on the package. It’s essential to ensure the packaging is intact and airtight to ensure the freshness and quality of the jerky.

The shelf life of beef jerky depends on whether it is homemade or store-bought. Generally, commercial beef jerky is best enjoyed within one year, but it can still be safe to eat even after that time.

Homemade beef jerky, on the other hand, should last for one to two months if stored in an airtight container after making it. Storing it properly will help maintain its freshness for a longer period.

It’s important to note that the flavor and texture of beef jerky may degrade over time, especially if it’s stored for an extended period. To enjoy the premium flavor and textures, it is recommended to consume beef jerky within six months of purchase.

If you’re unsure about the freshness of unopened beef jerky, there are a few indicators you can look out for. Check the color of the jerky – if it has changed or become darker or harder, it may have gone bad. Also, pay attention to any unusual or off-putting odors.

Buying beef jerky from trusted sources is crucial for ensuring its quality and safety. Look for properly sealed packaging and check the expiration date before purchasing.

Remember, if you have any doubts or concerns about the freshness of unopened beef jerky, it’s always best to consult a professional or contact the manufacturer.

Why Does Beef Jerky Last So Long?

Why Does Beef Jerky Last So Long

Let me tell you why beef jerky has such an impressive shelf life:

  1. Dehydration process: The magic of beef jerky lies in the dehydration process. By removing all the moisture, beef jerky becomes a shelf-stable product that can be stored without refrigeration.
  2. Lack of moisture: When combined with air-sealed packaging, the lack of moisture in beef jerky is a key factor in its long shelf life. This combination creates an environment where bacteria and other contaminants cannot thrive, allowing the jerky to stay fresh for an extended period.
  3. Proper packaging: Beef jerky makers stamp their products with a best-by date rather than an expiration date because when the jerky is made correctly, packaged, and stored, it does not expire. This means the jerky should remain safe if the packaging is intact.
  4. Storage conditions: To maximize the shelf life of beef jerky, it’s important to store it properly. Here are some key tips:
    • Keep it cool but not cold: Beef jerky does best in ambient room temperatures. Avoid storing it near the stove or other appliances that emit heat. Also, please keep it away from direct sunlight or bright light, as they can accelerate the degradation process.
    • Minimize exposure to oxygen: The best way to store beef jerky is in its original packaging. If you must transfer it to another container, ensure it’s airtight to reduce exposure to oxygen.
    • Dry and cool environment: Store your beef jerky in a dry, cool place like the back of the pantry or a cupboard. Regions with strong humidity can cause the bag to sweat, leading to potential issues.
  5. Trusted sources: Buying beef jerky from trusted sources is crucial. Make sure to start with a jerky that you can trust, as proper processing techniques and rigorous standards contribute to the long shelf life of commercial beef jerky.

How To Tell If Beef Jerky Has Gone Bad?

How To Tell If Beef Jerky Has Gone Bad

Here are some tips on how to determine if your beef jerky has spoiled:

  1. Check the best-by date: All beef jerky made in the USA must have a best-by date printed on the package. This date is usually located near the bottom seal of the bag. While it doesn’t necessarily mean it’s unsafe to eat after the best-by date; it’s a good starting point to determine if the jerky is still at peak freshness.
  2. Inspect the packaging: Look for any rips, tears, or holes in the packaging. If the package has been compromised, it may indicate that oxygen and moisture have entered the bag, potentially causing issues. Pay attention to the color, smell, and feel of the jerky.
  3. Look for signs of mold: Mold on beef jerky is a clear sign that it has spoiled. Mold appears as furry, powdery, or fuzzy foreign white, green, or grey foreign substances, often with a spider-web pattern. If you see mold, it’s best to discard the jerky and not consume it.
  4. Check for rancidity: Generally, beef jerky with higher fat content may develop a rancid smell. If the jerky has an off smell, it may have gone rancid and should not be eaten.

Remember, if the beef jerky passes these checks and shows no signs of mold or rancidity, it should be safe to eat. However, it’s always best to consult a professional if you have any doubts or concerns.

It’s important to note that beef jerky has a long shelf life due to the dehydration process and air-sealed packaging. Properly made and stored jerky does not expire. To extend the shelf life of your beef jerky, follow these tips:

What Happens If I Eat Spoiled Jerky?

What Happens If I Eat Spoiled Jerky

Eating spoiled jerky can lead to food poisoning, as spoiled meat is one of the worst things to consume. You may experience symptoms including nausea, abdominal pain, vomiting, diarrhea, fever, headaches, unexplained body aches, and jaundice (yellowing of the skin). If you consume enough spoiled jerky, you can become ill due to the bacteria it may contain, such as E. coli and Salmonella.

However, it is highly unlikely that you will get sick from eating spoiled jerky because you will be able to tell if it has gone bad before consuming enough to make you sick. The smell of spoiled jerky is usually enough to keep you from eating it, and even if you do, you’ll immediately spit it out because it will taste terrible.

Are There Any Storage Tips Or Techniques To Extend The Shelf Life Of Beef Jerky?

I’ve learned a few tricks to keep my jerky fresh and tasty for longer. Here are some storage tips and techniques you can try:

  1. Find the right storage environment: Storing your jerky in a dark, dry place is crucial to maintain its freshness. A pantry or a cool cupboard works well. Avoid storing it in direct sunlight or humid areas, as it can hasten spoilage.
  2. Use airtight containers: To keep your jerky fresh, transfer it to an airtight container after opening the original packaging. This helps to prevent exposure to air and moisture, which can lead to spoilage. Ziplock bags, paper bags, or mason jars can work as alternative options for storing your jerky.
  3. Vacuum sealing: If you want to take it further, consider investing in a vacuum sealer. Vacuum-sealed bags help to remove the air and keep the jerky moist and tender. This method is particularly useful if you make a lot of jerky or want to store it for an extended period.
  4. Freezing: Freezing beef jerky is an excellent way to extend its shelf life. Place your jerky in an airtight container or vacuum-sealed bag and freeze it. The freezing process slows the growth of bacteria and keeps the jerky fresh for up to 12 months or more.
  5. Avoid fatty cuts: Fat can contribute to the faster spoilage of jerky. It’s best to use lean cuts of meat when making your own jerky and remove any visible fat before drying. If you’re buying commercial jerky, opt for low-fat options.

Remember, beef jerky has a limited shelf life, even with proper storage. Keep an eye on any color, texture, or odor changes, as these can indicate spoilage. When in doubt, it’s best to err on caution and discard any jerky that seems off.


Does It Matter If Beef Jerky Is Stored At Room Temperature?

It’s okay to store beef jerky at room temperature, as the dehydration process makes it safe and shelf-stable. However, high heat and temperature fluctuations can affect the jerky’s taste and texture, so it’s best to keep it in an environment between 40°F and 75°F. Please don’t leave it in direct sunlight, as that can cause damage and loss of freshness. Homemade jerky should be refrigerated unless you can measure its water activity. Mason jars aren’t the best option for storing jerky because they can’t remove enough oxygen.

Does The Type Of Packaging Affect The Shelf Life Of Beef Jerky?

The type of packaging used for beef jerky can affect how long it stays fresh. It’s essential for the packaging to keep out oxygen and moisture because they can cause mold and make the jerky go bad. Strong packaging with a tight seal and an oxygen absorber inside can help keep the jerky fresh longer. Good packaging also makes it easier to carry and store the jerky, especially on the go.

The packaging design can make it look nice and appealing to customers. So, the type of packaging is really important for the shelf life of beef jerky.

Are There Any Preservatives In Beef Jerky That Help Prevent Spoilage?

Beef jerky has preservatives that help keep it from spoiling. Here’s why it stays fresh:

  • Jerky is made by marinating the meat in spices and vinegar, then drying it. This removes moisture and allows other ingredients to act as preservatives.
  • The marinade adds flavor and helps prevent the growth of harmful microorganisms.
  • Packaging it in an airtight bag and storing it in a cool, dark place also helps keep it from spoiling.
  • Vinegar and salt are the main preservatives used. Vinegar helps prevent spoilage and mold, while salt reduces the chance of rotting.
  • Other preservatives like sugar and spices can also make the jerky last longer.
  •  Proper dehydration and storage are essential. The moisture content should be less than 20% and kept at temperatures below 60°F.

Using the right amount of preservatives is important to ensure the jerky is safe to eat and won’t grow harmful bacteria like botulism. Check the jerky regularly for signs of spoilage like mold, bad odor, or discoloration, and throw away any that has gone bad.


In conclusion, beef jerky can go bad if not stored correctly, so it is crucial to take the necessary precautions. By understanding the factors contributing to spoilage and implementing proper storage methods, you can enjoy your beef jerky for an extended period. Stay mindful of the expiration date and any signs of spoilage, and you’ll be able to savor this delicious snack without any worries. So, does beef jerky go bad? Yes, it can, but you can enjoy it worry-free with the right care.
