Can You Eat Leftovers When Pregnant?
Written by Jordan Morley · Reviewed against NHS foods-to-avoid guidance · Last updated 28 October 2026
Leftovers are fine in pregnancy if they were chilled within 2 hours of cooking, are eaten within 2 days (UK advice), and are reheated once until steaming hot throughout.
Why are leftovers a concern in pregnancy?
There's nothing specific to pregnancy that makes leftovers riskier — the standard food safety rules just matter more, because pregnancy increases sensitivity to listeria and other foodborne bacteria. Cool leftovers and refrigerate within 1 to 2 hours of cooking (not left out overnight), eat them within 2 days (the Food Standards Agency says 48 hours, or freeze them; US pages that say 3 to 4 days are following the USDA), and reheat only once, until steaming hot all the way through. Rice is the one dish to be extra careful with, since it can carry heat-resistant Bacillus cereus spores if it's cooled slowly.
You can also check the calorie content of leftovers alongside their safety information. Also check medication safety during pregnancy if you're managing any conditions.
The exception
If leftovers have been sitting at room temperature for more than 2 hours, or it's been longer than 2 days in the fridge, bin them rather than risk it.
How long can I keep leftovers? UK and US advice differ
Most pages that rank for this question are American and say 3 to 4 days, or even more. UK guidance is shorter, and in pregnancy we use the shorter figure:
| Source | Fridge time | Other rule |
|---|---|---|
| UK Food Standards Agency | Cooked leftovers: eat within 48 hours (2 days) or freeze | Cool, then refrigerate within 1 to 2 hours |
| NHS (listeriosis page) | Opened food: use within 2 days unless the pack says otherwise | Keep the fridge at 5°C or below |
| New Zealand MPI (pregnancy guide) | Cooked leftovers: 2 days, covered | Reheat until piping hot, over 75°C |
| USDA (US) | Cooked leftovers: 3 to 4 days | Refrigerate within 2 hours (1 hour above 90°F) |
We use the UK 2-day limit on this site, counted from the day the food was cooked. The NHS also says not to eat food past its use-by date even if it looks and smells fine.
A timeline you can copy
| Sunday roast example | Time |
|---|---|
| Cooked and served | 1pm Sunday |
| In the fridge, in shallow containers (smaller portions cool faster) | By 3pm Sunday |
| Eat or freeze by | 1pm Tuesday |
| Reheat | Once only, until steaming hot all the way through |
Freeze leftovers as soon as possible after cooling them; thaw in the fridge and use within 24 hours (Food Standards Agency).
Which leftovers need extra care?
| Leftover | Care in pregnancy |
|---|---|
| Rice | Reheat only once, until steaming hot all the way through, and take extra care with takeaway rice (Food Standards Agency). Our own rule across this site is to chill rice within 1 hour |
| Cooked chicken, meat, stews, curries, soups | Reheat until steaming hot all the way through; stir while microwaving so there are no cold spots |
| Takeaway and restaurant leftovers | Count the 2 days from when it was cooked; if it sat in a delivery bag for hours, don't keep it |
| Pre-packed sandwiches, salads and ready-to-eat meals | Not leftovers: follow the use-by date, and for ready meals heat until steaming hot (NHS) |
| Home-made sushi and home-made custard | New Zealand MPI says not to eat leftover home-made sushi, and to reheat home-made custard until piping hot and eat it straight away |
Cold or reheated?
The Food Standards Agency says cooked leftovers can be eaten cold if they were cooked properly and cooled and refrigerated within 2 hours. That is a general rule for healthy adults. In pregnancy we suggest reheating until steaming hot anyway, which is a precaution of ours rather than an NHS rule. The NHS rule that does apply is to heat ready meals until they are steaming hot all the way through.
Ate something past its time?
It happens. The NHS tells you not to worry about foods that may carry listeria unless you have symptoms (fever, aches, chills, sickness, diarrhoea, stomach ache, reduced baby movement), and to contact your midwife, GP or NHS 111 urgently if you do. Tommy's says that if it didn't make you ill at the time, it is unlikely to have affected you or your baby. Our reading is that the same calm approach applies to leftovers a day past their time. The fix is the routine, not the guilt.

Common questions
Can I eat leftovers when pregnant?
Yes, if they were cooled and in the fridge within 2 hours of cooking, are eaten within 2 days (UK Food Standards Agency and NHS), and are reheated once until steaming hot all the way through. Don't eat anything past its use-by date.
How long can I keep leftovers when pregnant?
Two days in the fridge, counted from when the food was cooked, or freeze them as soon as they have cooled. Many US pages say 3 to 4 days (the USDA figure); UK advice is shorter and is the one to follow.
Can I eat 3-day-old leftovers when pregnant?
We would bin them: the UK limit is 2 days. If you have already eaten some, the NHS advice for foods that may carry listeria is that you do not need to do anything unless you get symptoms (fever, aches, chills, sickness, diarrhoea, stomach ache or reduced baby movement), in which case contact your midwife, GP or NHS 111 urgently.
Can I eat cold leftovers when pregnant?
The Food Standards Agency says cooked leftovers can be eaten cold if they were cooled and refrigerated within 2 hours. Reheating them until steaming hot is the cautious choice in pregnancy.
Can I reheat leftovers more than once when pregnant?
No. Reheat once only, until steaming hot all the way through. Rice should never be reheated more than once.
Is leftover rice safe in pregnancy?
It can be, if it was cooled quickly, refrigerated and is reheated once until steaming hot. The Food Standards Agency says to take extra care with takeaway rice, which is often pre-cooked and reheated before serving.
Can I freeze leftovers when pregnant?
Yes. Cool them first, freeze as soon as possible, label them, thaw in the fridge and use within 24 hours. You can freeze cooked food again but can reheat it only once after that.
