How Long Does Chicken Broth Last?

Opened chicken broth's 3-4 day fridge window is fairly short for a cooked liquid, reflecting how quickly a protein-rich, low-acid liquid like broth supports bacterial growth once it's out of a sealed, sterilized container — that combination of low acidity and dissolved protein is exactly the kind of environment bacteria thrive in.

A sour or off smell and any cloudiness beyond broth's normal light haze are the clearest signs a container has turned, and either one means it should be discarded rather than boiled and used anyway — a common but mistaken assumption is that reheating broth to a boil neutralizes spoilage, when in practice heat kills some bacteria but doesn't reliably eliminate toxins some strains produce. Store-bought broth in an aseptic carton, the shelf-stable kind sold unrefrigerated until opened, follows a different unopened timeline than a can or a homemade batch, but switches to the same 3-4 day countdown as any other broth the moment it's opened and refrigerated.

Homemade broth, lacking the commercial preservatives or the sterilizing high-heat process a shelf-stable carton goes through before it's opened, should be treated with more caution than a store carton nearing the far end of its printed date — when in doubt, the shorter 3-4 day window is the safer number to plan around for anything made at home. A carton of bone broth, marketed slightly differently from standard chicken broth but built on a similar simmered-liquid base, follows the same 3-4 day opened window once refrigerated — the marketing distinction between the two products doesn't reflect any real difference in how quickly either one can spoil after opening.
