How Long Does Bacon (Raw) Last?

An unopened package of bacon keeps about two weeks past its sell-by date in the fridge, considerably longer than an opened one, which should be treated as good for about a week once the seal is broken — the cure buys real time but doesn't make bacon immune to the usual spoilage clock.

Spoiled bacon announces itself with a sour, slightly rancid smell that's distinct from its normal smoky, salty aroma, along with a surface that's turned sticky or developed a dull, grayish cast rather than its usual pink-and-white marbling. Sugar-cured and peppered varieties don't keep meaningfully longer than plain bacon despite the extra ingredients, since neither sugar nor pepper functions as a real preservative at the quantities used. Keeping the original package resealed as tightly as possible, or transferring leftover strips to a dedicated airtight container, slows the surface oxidation that shortens usable life faster than almost anything else once the package is opened.

Bacon that's been left out at room temperature for more than two hours — say, forgotten on the counter after breakfast — should be treated as unsafe regardless of how many days remain in its printed fridge window, since the cure slows bacterial growth but doesn't stop it once the meat warms up.

A vacuum-sealed, unopened package that shows any ballooning or a strong off odor through the sealed wrap should be discarded without opening it further, since a compromised seal can let in bacteria well before the printed date would otherwise suggest.
