How Long Does Ground Beef (Raw) Last?

Ground beef's short 1-2 day fridge window exists because grinding mixes surface bacteria throughout the meat rather than leaving it confined to the exterior, which is also why ground beef needs to be cooked to a higher internal temperature (160°F) than a whole steak does — any bacteria present is distributed all the way through, not just on the surface a sear would otherwise handle. A grayish-brown color change alone isn't necessarily spoilage, since it can just be oxidation, but a sour smell, a sticky or slimy texture, or a color shift that comes paired with either of those are the real signs it's gone.

Buying ground beef in a package that's still cold to the touch, keeping it in the coldest part of the fridge rather than a door shelf, and cooking or freezing it within that 1-2 day window rather than pushing it to the edge all meaningfully reduce risk, since ground beef's short shelf life leaves very little margin for error compared to most other proteins on this site. A package that's ballooned slightly or feels unusually cold and stiff through the plastic can be a sign it partially froze and thawed in transit, which is worth a closer look at the color and smell before cooking, since that kind of temperature swing can shorten its remaining fridge life even within the stated window.
