How long leftovers actually last in the fridge
USDA FSIS guidance says to use cooked leftovers within 3 to 4 days. Health Canada says to eat refrigerated leftovers within 2 to 3 days, and UK guidance says to eat them within 48 hours or freeze them. These windows assume prompt chilling and a refrigerator at 4°C (40°F) or below. If you are unsure which guidance applies, use the shortest applicable window.
3 to 4 days in the US, 2 to 3 days in Canada, and 2 days in the UK — chill promptly and keep the fridge at or below 4°C (40°F).
Why the numbers differ
Refrigeration slows bacterial growth; it does not stop it. USDA FSIS says 3 to 4 days, Health Canada says 2 to 3 days, and UK guidance says 48 hours. The cited agencies do not say these differences are points on one shared Listeria growth curve, so it would be speculation to explain the gap that way. Follow the guidance for where you live, or use the shortest applicable window when cooking across regions.
The clock starts when the food is cooked, not when you notice it in the fridge. USDA FSIS and the UK guidance both stress refrigerating within 1 to 2 hours of cooking or serving; food left out longer than that has already spent time in the temperature range where bacteria multiply fastest (see our danger zone guide).
Storage windows by source
| Food | US (FDA) — fridge | US (FDA) — freezer | Canada (Health Canada) — fridge | UK (GOV.UK/FSA) — fridge |
|---|---|---|---|---|
| Cooked meat & meat dishes | 3-4 days | 2-3 months | 2-3 days (general leftovers guidance) | within 48 hours |
| Cooked poultry dishes | 3-4 days | 4-6 months | 2-3 days (general leftovers guidance) | within 48 hours |
| Soups & stews | 3-4 days | 2-3 months | 2-3 days | within 48 hours |
| Gravy & meat broth | 1-2 days | 2-3 months | 2-3 days (general leftovers guidance) | within 48 hours |
Freezer times in the FDA chart are for best quality, not safety — food held at 0°F (-18°C) stays safe indefinitely, it just loses texture and flavour over time.
Edge cases
- You froze it on day 2, not day 4. Freezing pauses bacterial growth but does not erase earlier storage or mishandling. Thaw safely, reheat only the portion you will eat to 165°F/74°C, and do not assume reheating starts a fresh multi-day refrigerator window. Health Canada says to discard uneaten leftovers after reheating; UK guidance says to reheat only once.
- It was a buffet or potluck dish. If it sat out unrefrigerated for more than 2 hours (1 hour above 90°F/32°C), USDA FSIS says discard it regardless of how long it's technically been since cooking — the storage-time guidance assumes it went into the fridge promptly.
- Rice, specifically. Cooked rice carries a separate risk (Bacillus cereus) and a shorter safe window than general leftovers — see our rice storage guide.
How GetLadle helps
GetLadle's Pantry view tracks what's in your fridge, freezer and cupboard alongside your meal plan, so a portion you cooked on Sunday doesn't get lost behind Wednesday's shop. It's a storage tracker, not a food-safety calculator — GetLadle doesn't set or enforce use-by dates, so the guidance above is still the thing to follow.

Frequently asked questions
Why do the US, Canada and UK give different numbers for leftovers?
Their published consumer guidance uses different limits: USDA FSIS says 3 to 4 days, Health Canada says 2 to 3 days, and UK guidance says 48 hours. The agencies do not establish in these sources that the difference comes from one shared Listeria model, so follow the guidance for where you live or use the shortest applicable window.
Does it matter what the leftovers are?
Yes. Storage charts can give food-specific limits, while Health Canada's current general leftovers guidance says 2 to 3 days. When in doubt, use the shortest limit that applies to the food in the container.
What if I'm not sure how long something has been in the fridge?
Throw it out. None of these agencies rely on smell or appearance as a safety check — bacteria that cause food poisoning don't always change how food looks or smells. If you can't say when it went in, treat the window as expired.
