How long leftovers actually last in the fridge
USDA FSIS guidance says cooked leftovers are safe in the refrigerator for 3 to 4 days. Health Canada gives the same 3 to 4 days for most cooked dishes (2 to 3 days for soups), provided the fridge holds 4°C (40°F) or below. UK guidance (food.gov.uk) is stricter: eat leftovers within 48 hours, or freeze them, and get them into the fridge within 1 to 2 hours of cooking. Use the shorter 2-day window if you are unsure which guidance applies, since it is the more cautious of the three.
3 to 4 days in the US and Canada, 2 days in the UK — refrigerate within 2 hours either way.
Why the numbers differ
Refrigeration slows bacterial growth, it doesn't stop it. The 3-to-4-day US and Canadian window and the UK's 2-day window are both built around the same two risks: ordinary spoilage bacteria and Listeria monocytogenes, which can grow slowly even at fridge temperatures. The regulators land on different numbers because they're drawing the line at different points on the same curve, not because one has better data than the other. If you cook for a mixed household — say, a Canadian recipe shared with a UK-based relative — using the shorter number is the safe default.
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 | 3-4 days | within 48 hours |
| Cooked poultry dishes | 3-4 days | 4-6 months | 3-4 days | 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 | 3-4 days | 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. That's fine — freezing effectively pauses the clock. Reheat it fully once thawed and treat the reheated portion as a fresh item for the next storage window.
- 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?
USDA FSIS and Health Canada both allow 3 to 4 days, based on how long it takes spoilage bacteria and Listeria to reach unsafe levels at a fridge temperature of 4°C (40°F). UK guidance is more cautious at 48 hours. None of the numbers are wrong; they're different safety margins from different regulators.
Does it matter what the leftovers are?
Yes. Soups and broths sit at 2 to 3 days per Health Canada, shorter than the 3 to 4 days for most cooked meat, poultry and mixed dishes. When in doubt, use the shortest number that applies to what's actually 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.
