How does vacuum packing affect safe meat storage time? - Grey Metal Lockers Is Open

I recently bought some vacuum-packed pork back ribs, with a sell-by date more than two weeks after I bought it. I don't think I've ever seen a date that far out on meats and I'm not sure how to interpret it. I assume it has something to do with the vaccum-packing.

I gather that meat isn't necessarily good until the sell-by date, because home refrigerators aren't as good at what they do as what the store uses. How long can I expect these ribs, and similar products, to last before I must cook them?



Best Answer

Vacuum-packing elongates food storage times because by removing the air you remove the oxygen, which aerobic organisms (in this case bacteria) thrive on. No oxygen means no bacterial growth. This is also known as Reduced Oxygen Packaging and can extend freezer life by years.

Some things to keep in mind:

  • If you open the package, it's life will drop considerably, and you will be back to a few days tops
  • If your package fills with air, either the seal broke, or a significant amount of oxygen was trapped inside and bacterial growth is generating decomposition gases.
  • If your food provider is a reputable source then their dating is probably accurate. There are significant regulations regarding ROP, and they probably have a production plan that monitors how the food is processed, with dates that are then determined by how the process works.
