2 hours max
Raw or cooked, then into the fridge (USDA)
1 to 2 days
Raw, at 40°F or below (USDA, NDSU)
Best within 4 months
Safe indefinitely frozen; 3 to 4 months for quality (USDA, NDSU)
The short version: to store ground beef, keep it at 40°F or below and cook or freeze it within 1 to 2 days. Frozen, it stays safe indefinitely and tastes best within 4 months. Thaw it in the fridge, and cook it to 160°F checked with a thermometer, not by color. A grey middle in the pack is normal, but grey all through, a sticky feel or a bad smell means it has gone.
Storage times, color and cooking advice here come from the USDA Food Safety and Inspection Service, with further figures from NDSU Extension and the USDA's FoodKeeper data.

What to check before you store ground beef
Two things decide how you store ground beef: how soon you will cook it and how cold it stays on the way home. With a 1 to 2 day clock, there is no room for a slow trip back from the store. So plan the meal, or plan the freezer, before you buy it.
Glass, a lid that seals, and a spoon that is properly dry.
Start with the package. The USDA Food Safety and Inspection Service says ground beef can go into the fridge or freezer in its original packaging if you will use it soon. Check that the wrap is sealed and the tray is cold to the touch.
Then look at the color, and expect two of them. FSIS explains that the surface is bright red because oxygen reacts with the meat's pigment, while the inside may be greyish brown from lack of oxygen. So a grey middle in a fresh pack is normal.
Next, get it cold fast. FSIS asks you to keep ground beef at 40°F or below, and that clock runs from the moment it leaves the store. So make it the last thing you pick up, and the first thing you put away.
Finally, decide on day one whether it is dinner or the freezer. Unlike a steak, which gets 3 to 5 days, ground beef gets 1 to 2. That short window is the whole reason this guide exists.
How to store ground beef so it lasts
To store ground beef so it lasts, keep it cold and keep the clock short. The fridge buys you a day or two, whereas the freezer buys you months, so most packs belong in the freezer the day you buy them.
How do you store ground beef in the fridge?
Ground beef keeps in the fridge at 40°F or below for 1 to 2 days, in its original package, according to the USDA Food Safety and Inspection Service. Leave it wrapped, and set it on a plate so no juice can drip onto other food. Check that your fridge really is that cold, since NDSU Extension builds its times on a fridge at 32 to 40°F.
Sealed, cool and dark, and nowhere near the cooker.
How long does ground beef last in the fridge?
Raw ground beef lasts 1 to 2 days in the fridge, according to the USDA Food Safety and Inspection Service, NDSU Extension and the USDA's FoodKeeper data. All three agree, which makes it one of the clearest numbers in food storage. The USDA Food Safety and Inspection Service repeats it as a rule of thumb: store it at 40°F or below and use it within 2 days, or freeze it.
Thawed ground beef gets the same short window. FSIS says ground beef thawed in the fridge should be cooked or refrozen within 1 or 2 days. So the clock resets once, but only if it thawed in the fridge.
Why is ground beef grey inside the package?
Ground beef is often grey or brown inside the package because the middle has no oxygen, and that alone is normal, according to the USDA Food Safety and Inspection Service. FSIS explains that oxygen turns the surface bright red, while fresh cut meat starts out purplish. However, it adds that if all the meat in the package has turned grey or brown, it may be beginning to spoil. So a grey core is fine, whereas a grey pack is a warning.
Can you tell if ground beef is cooked by its color?
Ground beef cannot be judged done by its color, because it can turn brown before it reaches a safe temperature, according to the USDA Food Safety and Inspection Service. FSIS cites a 1995 Kansas State University study in which enough patties browned before 160°F to make color unreliable. So use a food thermometer, and cook ground beef to 160°F in the thickest part.
How long does cooked ground beef last?
Cooked ground beef lasts about 3 to 4 days in the fridge and keeps its quality for about 4 months in the freezer, according to the USDA Food Safety and Inspection Service. That assumes it went into the fridge within 2 hours of cooking, or 1 hour above 90°F. When you reheat it, FSIS asks for 165°F, measured with a food thermometer.
Can you freeze ground beef?
Ground beef freezes well, and it stays safe indefinitely while frozen, although the USDA Food Safety and Inspection Service says it is best used within 4 months. NDSU Extension and the USDA's FoodKeeper give 3 to 4 months for quality. So aim for 3 months, and date every pack.
How do you freeze ground beef?
Ground beef can be frozen in its store package for short storage, but for longer it needs heavy-duty plastic wrap, foil, freezer paper or a freezer bag, according to the USDA Food Safety and Inspection Service. FSIS also asks you to mark the date on each package. Then press the meat flat in the bag before freezing, so the packs stack neatly and you can see the date at a glance.
Below 41 degrees it keeps for years, but it barely pours.
How do you thaw frozen ground beef?
Frozen ground beef thaws most safely in the fridge, and then it should be cooked or refrozen within 1 or 2 days, according to the USDA Food Safety and Inspection Service. For speed, use cold water in a watertight bag, changing the water every 30 minutes, or the microwave. In both of those cases, however, cook it straight away, and do not refreeze it raw.
Why does thawed ground beef release so much liquid?
Ground beef that has been frozen releases more juice when cooked, because ice crystals break the cell walls, according to the USDA Food Safety and Inspection Service. FSIS adds that some stores grind meat while it is still frozen, so the same thing can happen with fresh packs. It is a texture change, not spoilage. So pour off the liquid as it cooks, if you prefer a drier brown.
How to tell if ground beef has gone bad
Color is a poor test for ground beef, since a grey middle is normal. The reliable signs are smell, feel and the whole package turning grey. The USDA Food Safety and Inspection Service says spoilage bacteria make food develop a bad odor or feel sticky on the outside. Here is what each stage means, then.
Verdict: use it
Bright red, fresh ground beef
Bright red on the surface, cool and firm, with a clean smell. That is oxygen meeting the meat's pigment, as FSIS explains, so it is how fresh ground beef looks. Then cook it within 1 to 2 days, to 160°F.
Verdict: still fine
Ground beef grey in the middle
Red on the outside, greyish brown in the center of the pack. USDA Food Safety and Inspection Service guidance is that the inside may be grey from lack of oxygen. So if it smells clean and the outside is still red, cook it as planned.
Verdict: smell it, then decide
Ground beef grey all the way through
The whole pack has turned dull grey or brown, outside as well as in. FSIS says that when all the meat in the package has turned grey or brown, it may be beginning to spoil. So check the smell and feel. If both are clean and it is within its 1 to 2 days, cook it today. If not, throw it out.
Verdict: cut it off or use it soon
Freezer-burned ground beef
Dry, pale, greyish-brown patches on frozen ground beef. That is air reaching the surface, the same freezer burn FSIS describes on beef. It is a quality loss rather than a safety problem. So cut away the worst patches, and use the rest in a sauce or chili, where the texture matters least.
Verdict: throw it out
Sticky or sour-smelling ground beef
A slick or tacky surface, a sour or off smell, or both. The USDA Food Safety and Inspection Service names a bad odor and a sticky outside as the signs of spoilage bacteria. Cooking will not fix the smell or the risk. So bin it, wash your hands and anything it touched, and check any other meat from the same trip.
Can you eat ground beef left out overnight?
Ground beef left out overnight is not safe to eat, raw or cooked, because the USDA Food Safety and Inspection Service says never to leave it at room temperature for more than 2 hours, or 1 hour above 90°F. A night on the counter is many hours past that. So throw it out, then see the food left out overnight list for the rest of the meal.

Lentils
Chili and pasta sauce
Shelf-stable, so no fridge clock at all.
Mistakes people make when they store ground beef
These are the ways people store ground beef that cost them the most, and each one is easy to avoid.
Treating it like a steak. Ground beef gets 1 to 2 days in the fridge, not 3 to 5, so freeze it if dinner is later in the week.
Throwing out a pack that is grey in the middle. FSIS says a grey interior is normal, so check the smell and the outside first.
Judging burgers by color. FSIS says brown is not proof of doneness, so use a thermometer and cook to 160°F.
Thawing it on the counter. Thaw it in the fridge, or in cold water or the microwave and then cook it straight away.
Refreezing beef thawed in water or the microwave. FSIS says to cook it first before it goes back in the freezer.
Freezing it in a thick block in store wrap. Overwrap it and date it, as FSIS advises, so it keeps its quality.
Leaving cooked chili out all evening. Get leftovers into the fridge within 2 hours, then eat them within 3 to 4 days.
