Generally vacuum-sealed foods swell due to microbial growth in the food.
Vacuum sealers are devices which remove air from food items, thus increasing their lifespan. How much longer food will last with a vacuum sealer depends on the type of food sealed. Fresh meat may last 2-3 years vacuum sealed, while ground beef may last up to a year. By contrast, vacuum sealed cheese will only last about 6 months. Breads, on the other hand, may last only 6 weeks vacuum sealed.
Millman's theorem
Vacuum sealed hamburger meat that is frozen can last 2 to 3 months. When it is thawed, it shouldn't be kept in the refrigerator more than a couple days.
It shouldn't be left at room temperature. The vacuum packaging sets up a perfect environment for Clostridium botulinum.
Vacuum-sealed meats can last for up to a year, but the flavor gradually fades after the six-month mark. While the meat will still be edible a year or more later, it won't taste all that great.
