You opened a package of bacon four days ago, cooked some for breakfast, and left the rest in the fridge loosely wrapped. Now it is Monday. You have raw strips left and a container of cooked bacon from the weekend. Are both still good?
Does bacon go bad?
The short answer: Yes, bacon goes bad, and the timeline is shorter than most people assume. Raw bacon lasts 1 week in the refrigerator after opening per the USDA. Cooked bacon lasts 4 to 5 days refrigerated. Unopened raw bacon lasts up to 2 weeks in the fridge. Turkey bacon follows the same 1-week window after opening. All types freeze well and last 1 to 4 months frozen depending on the form.

How Long Does Bacon Last?
The USDA FSIS publishes specific guidance on bacon and food safety. For raw bacon, the refrigerator window is clear: unopened packages last up to 2 weeks, and opened packages should be used within 1 week. This applies to both regular pork bacon and turkey bacon. The USDA does not distinguish between the two for the 1-week opened window, though turkey bacon is leaner and some producers recommend using it within 3 to 5 days of opening for best quality.
Cooked bacon lasts longer than most people expect: 4 to 5 days refrigerated in an airtight container per USDA guidance and multiple producer sources. The cooking process kills off the bacteria present in raw bacon, and the salt and fat content slow re-colonization in the fridge. Many people assume cooked bacon needs to be eaten immediately, which is not true. Properly stored cooked bacon is a practical meal prep item.
| Type | Refrigerator (Unopened) | Refrigerator (After Opening) | Freezer |
|---|---|---|---|
| Raw pork bacon (sealed package) | Up to 2 weeks | 1 week (USDA) | Up to 4 months |
| Raw turkey bacon (sealed package) | Up to 2 weeks | 1 week (USDA); 3 to 5 days for best quality | Up to 4 months |
| Cooked bacon (pork or turkey) | N/A | 4 to 5 days | Up to 3 months |
| Shelf-stable precooked bacon (vacuum-sealed) | Until use-by date, stored at or below 85°F | 2 weeks after opening | Up to 6 months |
How to Tell If Bacon Has Gone Bad
Signs of Spoilage
- Sour or rancid smell: Fresh raw bacon has a mild, cured, slightly smoky smell. A sour, sharp, or distinctly rancid odor means the fat has oxidized or bacteria have taken hold. Do not cook it and hope the smell cooks off. Discard it.
- Slimy or tacky texture: Uncooked bacon should feel slightly moist when you pick it up but should not leave a slimy film. Sliminess is caused by Lactobacillus bacteria colonizing the surface and secreting a biofilm as they multiply. The meat is past its window. Discard it.
- Gray, brown, or green discoloration: Fresh raw bacon is pink to red with white or pale fat. Edges turning gray, a uniform gray-brown cast, or any green patches means spoilage. Some slight darkening at the very edge of slices from oxidation can be normal, but widespread or advancing discoloration is not.
- Mold: Any visible fuzzy growth on raw or cooked bacon means discard the entire package. Unlike hard cheeses, you cannot safely cut away a moldy section of bacon and use the rest.
The Shelf-Stable Precooked Bacon Exception
Most bacon requires refrigeration at all times. The exception is shelf-stable precooked bacon, which the USDA FSIS describes explicitly in its bacon and food safety guide. To make bacon shelf-stable, it is precooked in the plant until it reaches a water activity at or below 0.85, which controls Staphylococcus aureus growth. The cooked yield is approximately 40% of the raw weight. This product can be stored unopened at room temperature (at or below 85 degrees Fahrenheit per USDA guidance) and does not require refrigeration until opened. Use by the manufacturer’s recommended date printed on the package. Once opened, refrigerate and use within 2 weeks.
This is the product you occasionally see in grocery aisles on non-refrigerated shelves in vacuum-sealed or nitrogen-flushed packaging. It is a different product from the refrigerated raw or ready-to-cook bacon in the meat case.
Why Turkey Bacon Has a Slightly Shorter Quality Window
Per the USDA, turkey bacon follows the same 1-week refrigerated window after opening as pork bacon. However, turkey bacon is leaner, contains less fat, and has higher moisture content than pork bacon. Fat is a natural preservative that slows bacterial growth; the lower fat content means turkey bacon can degrade in quality faster even if it stays within the safety window. Many producers and food storage resources recommend using opened turkey bacon within 3 to 5 days for best flavor and texture, even though the USDA window is 1 week. Turkey bacon is also not technically bacon under USDA definition. By regulation, “bacon” can only be made from pork belly, and products made from other species must use a descriptive name like “turkey bacon” or “beef bacon.” This matters for labeling purposes but not for storage.
Can You Freeze Bacon?
Yes, and bacon freezes exceptionally well compared to most other deli and breakfast meats. The high fat content protects against ice crystal damage, and the curing preservatives maintain flavor through the freeze-thaw cycle. Freeze raw bacon in the original package if unopened. For opened bacon, wrap tightly in plastic wrap, then place in a zip-top freezer bag. Individual strips can be separated with parchment paper before freezing for easy single-strip use. The USDA FoodKeeper recommends using frozen raw bacon within 1 month for best quality. Many producer sources extend this to 4 months. Either way, frozen bacon remains safe indefinitely at 0 degrees Fahrenheit, though flavor and texture decline over time. Cooked bacon keeps for up to 3 months frozen. Thaw overnight in the refrigerator and use within 7 days of thawing. Do not refreeze once thawed.
Recipes That Use Bacon
If you have raw bacon approaching its window, cook it and store the cooked strips in the fridge for up to 5 days, which actually buys you more time than leaving it raw. Cooked bacon crumbles easily into salads, pasta, baked potatoes, soups, and egg dishes. We add crispy bacon to this recipe for roasted brussels sprouts. It is one of the most versatile refrigerator staples when batch-cooked ahead of time. For turkey bacon specifically, it is a lean protein option that works well in breakfast wraps and salads. See more on lean protein sources, see best sources of lean protein. For the USDA’s complete bacon and food safety guidance, see the USDA FSIS bacon and food safety page.
Does Bacon Go Bad FAQ
FAQ: How Long Does Canadian Bacon Last?
Canadian bacon (also called back bacon) is made from lean pork loin rather than belly. It is cured and fully cooked, which makes it more similar to a cooked deli meat than traditional strip bacon. Opened Canadian bacon lasts 3 to 5 days refrigerated. Unopened packages keep until the use-by date. It must always be refrigerated and does not have a shelf-stable version.
FAQ: Does Uncured Bacon Last as Long as Regular Bacon?
Uncured bacon contains no added sodium nitrate or nitrite, instead using naturally occurring nitrates from ingredients like celery powder. The USDA recommends following the same refrigeration and storage guidelines for uncured bacon as for traditionally cured bacon: refrigerate at 40 degrees Fahrenheit, use within 1 week of opening, and follow the package date. Some food scientists note that uncured bacon may have a slightly shorter practical shelf life because nitrates contribute to preservation, but the USDA does not publish a separate shelf life figure for uncured products. When in doubt, use it earlier in the window rather than later.
FAQ: Can You Cook Bacon That Has Gone Slightly Bad?
No. Cooking bacon that has a sour smell or slimy texture does not make it safe. Heat kills bacteria but does not neutralize the toxins some bacteria have already produced in the meat. If bacon smells sour or feels slimy before cooking, discard it. The one exception is very slight graying at the edges with no smell change, which can be oxidation rather than spoilage. If in doubt, do not cook it.
FAQ: How Long Does Cooked Bacon Last at Room Temperature?
Cooked bacon left at room temperature follows the standard USDA 2-hour perishable food rule. After 2 hours at room temperature (or 1 hour above 90 degrees Fahrenheit), cooked bacon should be refrigerated or discarded. This applies whether it is in a pan on the stove, on a plate on the counter, or in a warming tray at a buffet. Bacon’s salt and fat content give it some natural resistance, but not enough to override the 2-hour guideline safely.
FAQ: Is Bacon Still Good After the Sell-By Date?
Often yes, for unopened packages. The sell-by date is a guide for retailers, not a hard safety expiration. An unopened package of raw bacon that has been kept continuously refrigerated and has not been damaged can often be used a day or two past the sell-by date if it passes smell and appearance checks. Once opened, the sell-by date matters much less than the 1-week window from when you first broke the seal. Never use bacon past the use-by date if one is printed, and always rely on sensory checks regardless of the date.
