You bought a package of bacon and left it on the counter while you unpacked the groceries. Now it has been sitting out for about 45 minutes. You are wondering whether bacon really needs to go straight back in the fridge, or whether it can sit out a bit longer while you get organized.
Does bacon need to be refrigerated?
The short answer: Yes, raw bacon and most cooked bacon must be refrigerated at all times. There is one exception: shelf-stable precooked bacon, which has been processed to a specific moisture level that allows room-temperature storage before opening. For everything else, refrigerate at 40 degrees Fahrenheit or below and discard if left out more than 2 hours.
For more on perishable food storage, see the Food Storage Guide.
Key Takeaways
- Raw bacon: must be refrigerated at all times
- Cooked bacon: must be refrigerated; use within 4 to 5 days
- Left out more than 2 hours: discard
- Shelf-stable precooked bacon: room temperature before opening; refrigerate after opening
- Store raw bacon in coldest part of fridge, away from other foods to prevent cross-contamination
Does Raw Bacon Need to Be Refrigerated?
Yes, at all times. Raw bacon is an uncooked pork product that requires continuous refrigeration at 40 degrees Fahrenheit or below from the moment you bring it home from the store. It was stored in the refrigerated meat case at the grocery store, and it belongs in your refrigerator immediately upon arriving home. The USDA FSIS states explicitly that raw bacon must be kept refrigerated to maintain safety. Left at room temperature for more than 2 hours, raw bacon should be discarded.
Brief exposure during grocery unpacking (15 to 20 minutes) is not a concern. The 2-hour rule covers cumulative time at room temperature in the danger zone between 40 and 140 degrees Fahrenheit, not a momentary counter rest.
Does Cooked Bacon Need to Be Refrigerated?
Yes. Cooked bacon must be refrigerated if not consumed immediately. Once cooked and cooled to room temperature, place it in an airtight container and refrigerate within 2 hours of cooking. Do not leave cooked bacon sitting on a plate on the counter after a meal. Refrigerated properly, cooked bacon lasts 4 to 5 days.
One practical tip: batch-cooking bacon and storing it cooked in the fridge is actually a smart use of a package approaching its raw window. Cooking the raw bacon before it reaches the end of its 1-week opened window converts it into cooked bacon with a 4 to 5 day fridge life, effectively buying you more usable time than leaving it raw.
The Shelf-Stable Precooked Bacon Exception
The one type of bacon that does not require refrigeration before opening is shelf-stable precooked bacon. According to the USDA FSIS, to be classified as shelf-stable, precooked bacon must be processed in the plant to a water activity at or below 0.85, which controls the growth of Staphylococcus aureus at room temperature. The USDA recommends storing it at or below 85 degrees Fahrenheit and using it by the manufacturer’s recommended date. This product is typically found in vacuum-sealed packaging on unrefrigerated grocery shelves rather than in the meat case.
Once opened, shelf-stable precooked bacon must be refrigerated and used within 2 weeks. If you are unsure whether your precooked bacon is shelf-stable or not, look at where it was sold: if it was in the refrigerated meat case, keep it refrigerated. If it came from an unrefrigerated aisle, it is shelf-stable until opening.
How to Store Bacon Correctly
Raw Bacon
- Keep in original sealed packaging until use. The vacuum seal significantly extends shelf life.
- Once opened, wrap remaining strips tightly in plastic wrap or transfer to a zip-top bag, pressing out as much air as possible.
- Store on a lower interior shelf or in the meat drawer, not in the door. The door is the warmest spot in the fridge.
- Keep away from ready-to-eat foods and store below other foods to prevent raw pork drip contamination.
- Use within 1 week of opening per USDA guidance.
Cooked Bacon
- Let it cool briefly on a paper towel to drain excess fat, then transfer to an airtight container.
- Do not leave cooked bacon at room temperature for more than 2 hours.
- Store in a single layer or between paper towels in a sealed container to prevent sogginess.
- Use within 4 to 5 days.
- To reheat: microwave for 20 to 30 seconds, or warm in a skillet over medium heat. Do not reheat more than once.
Freezing Bacon
- Raw: freeze in original sealed packaging if unopened. For opened packages, wrap tightly in plastic wrap and place in a freezer bag.
- Separate strips with parchment paper before freezing so individual strips can be pulled without thawing the full package.
- Raw bacon: up to 4 months frozen. Cooked bacon: up to 3 months.
- Thaw overnight in the refrigerator. Use within 7 days of thawing. Do not refreeze once thawed.
Recipes That Use Bacon
If your bacon is approaching the end of its window, cook it. Batch-cooked bacon crumbles beautifully into salads, pasta, soups, baked potatoes, and egg dishes and lasts 4 to 5 days in the fridge. We love bacon in this roasted brussels sprouts recipe. Turkey bacon works particularly well in lighter preparations.

Bacon Storage Guide FAQ
FAQ: Can Bacon Sit Out Overnight?
No. Raw or cooked bacon left at room temperature overnight should be discarded. The USDA 2-hour rule applies: any perishable food left in the temperature danger zone (between 40 and 140 degrees Fahrenheit) for more than 2 hours should not be eaten. Bacon that sat out overnight has been in that zone for 8 or more hours. Even if it looks and smells fine, bacterial levels may have reached unsafe concentrations without producing detectable signs.
FAQ: Does Unopened Bacon Need to Be Refrigerated?
Yes, for all standard raw and cooked refrigerated bacon. The sealed vacuum packaging significantly extends shelf life but does not make the product shelf-stable. An unopened package of raw bacon stored in the fridge continuously lasts up to 2 weeks. If it came from the refrigerated meat case at the store, it must stay cold even in the original sealed package. The only exception is shelf-stable precooked bacon sold from unrefrigerated shelves, which can be stored at room temperature until opening.
FAQ: Can You Store Bacon Grease at Room Temperature?
Bacon grease stored in a sealed container can be kept at room temperature for up to a month according to food safety experts, though refrigeration extends its life to 3 months or more. The high fat content and lack of water make it significantly more shelf-stable than bacon itself. However, if your bacon grease contains any food particles or bits of bacon, refrigerate it promptly to prevent rancidity and bacterial growth from the protein-containing particles.
