Vacuum sealing is one of the most effective ways to preserve meat and extend its shelf life. By removing most of the air from the package, vacuum sealing prevents oxygen from reaching the meat and causing it to spoil through oxidation. This slows down the growth of bacteria significantly. With proper vacuum sealing and storage, meat can last between 1 to 3 years past its original expiration date.
What is vacuum sealed meat?
Vacuum sealed meat refers to raw or cooked meat that has been placed in a plastic pouch or bag, then had most of the air removed from the package using a vacuum sealer machine. This process removes oxygen and prevents it from reaching the meat, which is what causes it to spoil. The bag is then sealed shut to prevent air from re-entering.
Vacuum sealing gives meat a much longer shelf life compared to just placing it in a ziplock bag or plastic wrap. It creates an oxygen-free environment where bacteria cannot thrive. While it does not completely halt the growth of microbes, it slows it down considerably. Vacuum sealed meat, if stored properly, can last between 1 to 3 years past the printed expiration date on the original package.
Factors that affect how long vacuum sealed meat will last
There are several factors that affect the shelf life of vacuum sealed meats:
Type of meat
The type of meat makes a difference in how long it will last vacuum sealed. Meat can be categorized into two types:
- Red meat – This includes beef, lamb, venison, bison, etc. Red meats have a shorter shelf life compared to white meats when vacuum sealed. They will last between 1 – 1.5 years past the printed expiration date.
- White meat – This includes chicken, turkey, pork, fish, etc. White meats generally last longer than red meats, between 2 – 3 years past the printed expiration date when vacuum sealed.
Freshness of meat before sealing
The freshness of the meat before you vacuum seal it also determines its shelf life. Meat that is already close to spoiling will have higher bacteria levels and likely won’t last as long. Vacuum sealing meat that still has several days before reaching its expiration date will extend its life the longest.
Temperature of storage
Temperature plays a huge role in how long vacuum sealed meat will last. The cooler the environment, the better. Storing vacuum sealed meat in the refrigerator at 40°F or lower provides the longest shelf life. Storing it in the freezer below 0°F can allow it to last between 2 – 3 years.
Opening the package
Once the vacuum sealed package has been opened, oxygen is re-introduced. This kickstarts bacterial growth again. Meat that has been opened needs to be eaten within 1 week. Re-sealing it can extend it another week or two at most.
How long does vacuum sealed meat last at room temperature?
Vacuum sealed meat can last between 1 – 2 weeks at room temperature before spoiling. However, this is not recommended. Meat left out at room temperature for over 2 hours should not be consumed due to risk of bacteria growth. Vacuum sealing slows down but does not stop bacteria over time. For food safety, vacuum sealed meat is best stored in the refrigerator.
How long does vacuum sealed meat last in the fridge?
Vacuum sealed meat that is continuously stored in the refrigerator at 40°F or lower can last between 1 – 3 years past the printed sell-by or use-by date, depending on the type of meat.
Here are the approximate fridge shelf life for vacuum sealed meats:
| Type of Meat | Refrigerator Shelf Life |
|---|---|
| Beef, lamb, bison | 1 – 1.5 years past sell-by date |
| Pork | 2 – 3 years past sell-by date |
| Poultry | 2 – 3 years past sell-by date |
| Fish and seafood | 2 – 3 years past sell-by date |
Proper cold storage is key to maximizing how long vacuum sealed meat will last. Make sure your refrigerator is set to 40°F or below. Use a refrigerator thermometer to verify the temperature if needed.
Signs vacuum sealed meat has spoiled in the fridge
Despite cold storage, vacuum sealed meat can still spoil eventually. Check for these signs that indicate spoiled meat:
- Foul, rancid odor when package is opened
- Discoloration, sliminess or mold on the meat
- Off-putting grayish color instead of bright red (for red meats)
- Dry, sticky texture instead of moist
If vacuum sealed meat exhibits any of these signs, it has spoiled and should be discarded. Do not taste or consume spoiled meat.
How long does vacuum sealed meat last in the freezer?
For maximum shelf life, store vacuum sealed meat in the freezer below 0°F. Meat stored constantly at freezing temperatures can last between 2 – 3 years past the printed expiration date.
Here are the approximate freezer shelf lives of vacuum sealed meats:
| Type of Meat | Freezer Shelf Life |
|---|---|
| Beef, lamb, bison | 2 – 2.5 years past sell-by date |
| Pork | 2 – 3 years past sell-by date |
| Poultry | 2 – 3 years past sell-by date |
| Fish and seafood | 2 – 3 years past sell-by date |
Make sure your freezer is at 0°F or below to get the maximum shelf lives. Use a freezer thermometer to verify the temperature.
Signs vacuum sealed meat has spoiled in the freezer
Vacuum sealed meat stored in the freezer can still spoil eventually. Look for these signs of spoiled frozen meat:
- Ice crystals inside the package or frost buildup
- Meat has turned gray, brown or rancid smelling
- Meat is dried out upon thawing
- Discoloration or dry, sticky texture
If you notice any of these, the meat has likely spoiled and should not be eaten. Discard immediately.
Thawing and eating vacuum sealed meat
To eat vacuum sealed meat, you must thaw it first if frozen. Do not thaw meat at room temperature, as bacteria can start growing again. Here are some safe ways to thaw vacuum sealed meat:
- In the refrigerator – Place sealed package on a plate to catch drips. Thaw for 24-48 hours depending on size.
- In cold water – Place sealed meat bag in cold water, changing water every 30 mins. Thaw for 2-3 hours.
- In the microwave – Use the defrost setting based on weight. Cook immediately after thawing.
Once thawed, refrigerate for use within 3-5 days. Do not refreeze raw meat after it has thawed.
Cook vacuum sealed meat to a safe internal temperature before consuming:
- Beef, pork, lamb, fish – 145°F
- Poultry – 165°F
This eliminates any bacteria that may have developed.
Tips for maximizing shelf life of vacuum sealed meats
Follow these tips to get the longest shelf life out of your vacuum sealed meats:
- Purchase fresh meat as close to the “sell-by” date as possible.
- Ensure meat surfaces are dry before sealing to prevent moisture buildup.
- Seal meats in smaller portions to limit air exposure when opening.
- Label bags with contents and date before freezing.
- Avoid opening and resealing bags multiple times.
- If opened, use within 1 week or re-freeze immediately.
- Store sealed meat constantly at 0°F or below for longest shelf life.
Conclusion
Vacuum sealing can extend the shelf life of meats by 1 – 3 years past the printed expiration date if stored properly. Meat type, freshness, storage temperature and handling all affect how long vacuum sealed meat will last. Keep it refrigerated or frozen to get the maximum shelf life.
Check for signs of spoilage before consuming any vacuum sealed meats. Cook to safe internal temperatures prior to eating. Follow proper vacuum sealing and food safety practices to enjoy preserved meat for your long term food storage needs.
