Lamb

“Lamb” is two storage questions. Ground lamb and whole cuts (chops, steaks, roasts) follow different refrigerator windows on FoodSafety.gov / USDA charts — open the page that matches what is in your fridge. Past a fridge window, discard it. Fridge = safety; freezer = quality.
Ground lamb fridge 1–2 days · freezer 3–4 months spoils fast — cook or freeze Lamb mince — short refrigerator window like other ground meats; cook to 160°F. Lamb chops fridge 3–5 days · freezer 4–12 months standard windows Chops, steaks, and roasts — longer fridge window than ground; cook to 145°F with a rest.

Fridge vs freezer

FoodSafety.gov groups ground lamb with other ground meats (short fridge safety window) and lamb chops/roasts with other whole cuts (longer fridge window). Freezer months are quality guidance at 0°F; frozen lamb remains safe indefinitely while quality declines (cold chart).

How to tell lamb is spoiled

Sour or off odor, sticky slime, and dull gray-brown color across the surface mean discard it. A strong “lamby” aroma when fresh is normal; a sharp sour or ammonia note after storage is not. Do not taste to check. Danger-zone time above 40°F still forces a discard even without odor (danger zone).

Storage tips

Safety notes

There is no separate FSIS “lamb from farm to table” page in our citation set; durations follow the FoodSafety.gov cold chart rows for ground meat and steaks/roasts. When a source is silent on a detail, we leave that detail out rather than invent it. Not medical advice.
