Bacon shelf life, answered
How long does bacon last in the fridge?
1 week at 4°C (40°F) or colder (opened). Count from the day it was cooked, opened or bought.
How long does bacon last in the freezer?
1 month for best quality at -18°C (0°F). Frozen food stays safe indefinitely; after that, texture and flavour fade.
How long does bacon last at room temperature?
No more than 2 hours, or 1 hour above 32°C (90°F). Perishable food left out longer should be thrown away.
How long does bacon last after opening?
1 week in the fridge once opened. The printed date stops applying the moment you break the seal.
How long does unopened bacon last?
1 week in the fridge, if the seal is intact and it is stored as the label says.
How long is bacon good for past the expiration date?
FoodKeeper gives unopened bacon 1 week in the fridge, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
How can you tell if bacon is bad?
Sour or rancid smell instead of smoky or salty. Slick, slimy surface on slices or links. Grey, green or iridescent patches that spread.
How long can bacon sit out?
2 hours at room temperature, 1 hour on a hot day above 32°C (90°F). Overnight is always too long.
Signs bacon has gone bad
Smell
Sour or rancid smell instead of smoky or salty.
Texture
Slick, slimy surface on slices or links.
Colour
Grey, green or iridescent patches that spread.
Mould
Fuzzy spots on sliced or cooked products — discard.
Can you freeze bacon?
- 1Step 1
Freeze in the original vacuum pack if unopened; otherwise wrap slices in plastic and foil.
- 2Step 2
Freeze in meal-size portions so you only thaw what you need.
- 3Step 3
Thaw in the fridge; texture of sliced meats softens slightly after freezing.
How to thaw bacon
In the fridge
Safest. About 24 hours per 2.3 kg (5 lb); small packs overnight. Raw meat and seafood then keep 1–2 more days.
In cold water
Seal it in a leak-proof bag, submerge, and change the water every 30 minutes. About 30 minutes per 0.5 kg (1 lb). Cook right away.
In the microwave
Use the defrost setting and cook immediately, because parts of the food may start to cook.
How to reheat bacon safely
Reheat to 74°C (165°F)
Check the thickest part with a food thermometer; it should be steaming hot all the way through.
Only once
Reheat just the portion you will eat. Each cool-and-reheat cycle gives bacteria another chance.
Cover and stir
In the microwave, cover the dish and stir halfway so there are no cold spots.
From the freezer
Thaw in the fridge first, or reheat straight from frozen and allow extra time.
Bacon left out overnight
Bacon left at room temperature for more than 2 hours (1 hour above 90°F / 32°C) should be thrown away. Bacteria multiply fastest between 40°F and 140°F, and reheating does not remove every toxin they make.
Bacteria multiply fastest between 4 °C and 60 °C (40–140 °F).
