Cryovac packaging helps extend the shelf life of fresh pork, but how long does it actually last in the refrigerator? Here is a detailed guide on cryovac pork, proper storage signs of spoilage, and how long it stays fresh in the fridge.
What is Cryovac Packaging?
Cryovac is a brand name for a type of vacuum sealing technology used to package fresh meats It removes oxygen from packages and seals the contents in an airtight environment
This lack of oxygen inhibits bacterial growth and oxidation reactions that cause spoilage. It allows meat to stay fresh longer compared to traditional store wrapping.
Cryovac is a popular packaging choice among meat suppliers, retailers, and consumers looking to extend pork’s shelf life. It comes in large bags for bulk pork cuts or in sealed trays for individual packages.
How Long Does Cryovac Pork Last in the Fridge?
Unopened cryovac packaged pork can be refrigerated for 10-14 days past the pack date if kept at 40°F or below.
Once opened, it’s best to use cryovac pork within 3-5 days.
Proper refrigeration is key – pork lasts longest when stored at the optimal fridge temp of 34-40°F.
Higher temperatures allow more rapid bacteria growth. Check your fridge temp if in doubt.
