Beef
Fridge vs freezer
Grinding mixes surface bacteria through the meat, so FoodSafety.gov gives ground beef a shorter refrigerator window than steaks and roasts. Fridge times are safety windows — past them, discard it. Freezer times are quality windows; beef held at 0°F stays safe indefinitely (FoodSafety.gov cold chart; USDA FSIS ground-beef guidance).
How to tell beef is spoiled
Sour or ammonia-like smell, sticky slime, and gray-brown color across the surface (not just the oxygen-starved interior of a ground tray) are spoilage signs — discard it. Pathogens such as E. coli O157:H7 do not always make meat smell bad (FSIS ground beef). Do not taste to check. If beef sat in the danger zone too long, discard it even when it looks normal.
Storage tips
- Store raw beef on the bottom shelf so juices cannot drip onto ready-to-eat food.
- Leave it in store packaging until cooking, or overwrap leaky trays in a sealed bag.
- Thaw in the refrigerator only; cook ground beef soon after thawing.
- Cook ground beef and patties to 160°F; steaks and roasts to 145°F with a 3-minute rest ( safe cooking temperatures).
Safety notes
FSIS treats ground beef as higher risk than intact steaks because grinding distributes bacteria throughout. A pink center in a burger is not a safety check — use a thermometer. Printed “sell by” dates are not a free extension of the cold-chart fridge window ( date labels).
