Okay—what matters next is what you want to do with it and how it’s been stored.
If you bought raw ground beef yesterday and kept it refrigerated (around 4°C / 40°F or below):
⏱️ How long it’s safe
- Raw ground beef is generally safe in the fridge for 1–2 days
- So if it was bought yesterday, it’s still within the safe window today
👃 How to check it before cooking
Even within the safe timeframe, do a quick check:
Likely OK if:
- Smells neutral or slightly “meaty”
- Color is bright red or slightly brown (brown alone is not spoilage)
- No sticky or slimy texture
Do NOT use if:
- Strong sour, ammonia-like, or rotten smell
- Slimy or tacky surface
- Gray-green discoloration with bad odor
- Package is swollen or leaking
🍳 Cooking safety
If it looks/smells fine:
- Cook thoroughly to 74°C (165°F) internal temperature
- Ground beef must be fully cooked (no pink center if you’re being cautious)
⚠️ Important nuance
Ground beef spoils faster than whole cuts because:
- More surface area exposed to bacteria
- Grinding mixes surface bacteria throughout the meat
That’s why the 1–2 day rule matters more strictly than for steaks.
Bottom line
If it’s been in the fridge since yesterday and looks/smells normal, it’s generally safe to cook today.
If you want, tell me:
- exact purchase date/time
- whether it was opened or sealed
- fridge temperature (if you know it)
I can give you a more precise “safe or toss” judgment.
