How Long Does Ground Beef Last?

How long does raw ground beef last in the fridge?

Raw ground beef lasts 1-2 days in the fridge when stored at 40 degrees F or below. The shorter shelf life compared to whole-cut beef (3-5 days) comes from the grinding process: surface bacteria from the outside of the beef get mixed throughout the meat, giving bacteria more opportunity to grow on the increased surface area. Store raw ground beef on the bottom shelf in the original packaging if intact, or transfer to a leak-proof container. Use within 1-2 days of purchase. The 'sell by' date on grocery store packaging is when stores must sell by; you have 1-2 days from that date to cook or freeze.

How long does cooked ground beef last?

Cooked ground beef lasts 3-4 days in the fridge stored in airtight containers at 40 degrees F or below. Cool cooked ground beef to room temperature within 2 hours of cooking before refrigerating. Crumbled cooked ground beef (for tacos, chili, pasta sauce) stores best in shallow containers for faster cooling and easier portion control. Cooked hamburger patties last 3-4 days; store individually wrapped or in airtight containers. Cooked ground beef in sauces, casseroles, or soups lasts 3-4 days; the moisture-rich environment doesn't extend the safety window. Always reheat cooked ground beef to 165 degrees F internal temperature before eating.

How long does frozen ground beef last?

Frozen raw ground beef lasts 3-4 months at 0 degrees F for best quality (safe indefinitely but quality degrades). Cooked frozen ground beef lasts 2-3 months. The shorter freezer life for ground beef compared to whole-cut beef (6-12 months) comes from increased surface area exposing more meat to oxidation and freezer burn. To freeze raw ground beef: divide into 1-pound portions, flatten into thin disks (1/2 inch thick), wrap tightly in plastic, then foil or freezer paper, and place in a freezer bag with air pressed out. The flat-disk method allows fast thawing in the fridge or cold water and easier portioning. Label with the date and weight. Frozen ground beef should be thawed in the refrigerator (preferred), cold water, or microwave; never on the counter.

How can you tell when ground beef has gone bad?

Bad ground beef shows clear signs. Sour or rancid smell distinct from the mild fresh-beef aroma indicates spoilage. Slimy or sticky texture on the surface indicates bacterial growth. Gray or green discoloration throughout the meat indicates spoilage; ground beef naturally turns slightly gray on the inside due to oxygen deprivation (without color change being a problem) but the outside should be red when fresh. If both inside and outside are uniformly gray-green, the meat has likely spoiled. Mold (rare but possible) means immediate discard. Bulging or leaking packaging indicates internal bacterial growth. Cooked ground beef shouldn't have any sliminess, off-smell, or unusual color; any of these signs means discarding. Trust your nose: the smell test catches most ground beef spoilage before any safety risk emerges.
