Vacuum sealing removes air to slow freezer burn and spoilage from oxygen, but it does not kill bacteria. Some harmful bacteria, including Clostridium botulinum, grow without oxygen. Perishable vacuum-sealed food must still be refrigerated or frozen.
Food storage reference guide
Refrigerator times assume 40°F (4°C) or colder; freezer times assume 0°F (−18°C). Freezer times are for best quality — food kept constantly at 0°F stays safe indefinitely. Vacuum sealing does not replace refrigeration and does not make spoiled or unsafe food safe.
| Food | Refrigerator (40°F) | Freezer (0°F, quality) | Room temperature | Notes |
|---|---|---|---|---|
| Steaks (beef, lamb, pork) Meat | 3–5 days | 6–12 months | Keep refrigerated | Vacuum sealing mainly prevents freezer burn; fridge safety times stay the same. |
| Chops Meat | 3–5 days | 4–6 months | Keep refrigerated | Pat dry before sealing; pad bone edges. |
| Roasts Meat | 3–5 days | 4–12 months | Keep refrigerated | |
| Ground meat Meat | 1–2 days | 3–4 months | Keep refrigerated | Press flat in the bag for fast freezing and thawing. |
| Bacon Meat | 7 days | 1 month | Keep refrigerated | |
| Chicken, whole Poultry | 1–2 days | Up to 1 year | Keep refrigerated | |
| Chicken pieces Poultry | 1–2 days | 9 months | Keep refrigerated | |
| Lean fish (cod, tilapia, flounder) Fish & seafood | 1–2 days | 6–8 months | Keep refrigerated | Open the vacuum package before thawing fish (botulism precaution). |
| Fatty fish (salmon, mackerel) Fish & seafood | 1–2 days | 2–3 months | Keep refrigerated | Open the vacuum package before thawing fish. |
| Cooked leftovers (meat, poultry) Cooked food | 3–4 days | 2–6 months | Keep refrigerated | Cool quickly before sealing. |
| Soups & stews Cooked food | 3–4 days | 2–3 months | Keep refrigerated | Pre-freeze in a container, then vacuum seal the solid block. |
| Blanched vegetables Vegetables | — | 8–12 months | No | Blanch first to stop enzyme activity. |
| Broccoli, cauliflower, cabbage Vegetables | Do not vacuum seal for the fridge | 8–12 months (blanched) | No | Cruciferous vegetables release gases — blanch and freeze only (manufacturer guidance). |
| Raw mushrooms, garlic, onions Vegetables | Do not vacuum seal raw | — | No | Manufacturers advise against vacuum packaging these raw (low-oxygen risk). |
| Hard cheese (cheddar, Swiss) Dairy | 3–4 weeks opened; 6 months unopened | 6 months | Keep refrigerated | Vacuum sealing helps prevent drying and mould on cut faces. |
| Soft cheese (Brie, ricotta) Dairy | Do not vacuum seal | — | Keep refrigerated | Manufacturers advise against vacuum packaging soft cheeses. |
| Coffee beans, rice, pasta, nuts Dry goods | Not required | Optional | Yes – cool, dry, dark place | Vacuum sealing slows staling and keeps pests out; nuts last longer frozen. No official time limits. |

How to read this chart
- Refrigerator times are for food kept at 40°F (4°C) or below. Vacuum sealing doesn’t safely extend these limits for raw meat, poultry and fish.
- Freezer times are for best quality at 0°F (−18°C). Food kept constantly frozen stays safe indefinitely, but flavour and texture decline over time. Good vacuum sealing helps food reach the longer end of these ranges by preventing freezer burn.
- Room temperature applies only to shelf-stable dry goods. Perishable food should not sit out for more than 2 hours.
Thawing safely
Thaw vacuum-sealed food in the refrigerator, in cold water in its leak-proof bag (changing the water every 30 minutes), or in the microwave if you’ll cook it immediately. Never thaw on the counter. For vacuum-packed fish, open the package before thawing.
