Can You Eat Cooked Ham When Pregnant?
Written by Jordan Morley · Reviewed against NHS foods-to-avoid guidance · Last updated 28 October 2026
The NHS lists processed, cold pre-cooked meats such as cooked ham under foods to be careful with: keep it chilled and eat it before the use-by date. It is not on the avoid list.
Why is cooked ham a concern in pregnancy?
The NHS foods-to-avoid page (last reviewed 15 June 2026) lists 'processed, cold pre-cooked meats, such as ham or chicken' under foods to be careful with: keep them chilled and eat them before the use-by date. It also says some ready-to-eat foods, like pre-packaged sandwiches and salads, may contain listeria bacteria. Cold cured meats such as salami and prosciutto are handled separately: they should be cooked until steaming hot before eating. Some US sources go further and suggest heating deli meat until steaming hot; the NHS does not ask for that for cooked ham.
You can also check the calorie content of cooked ham alongside its safety information. Also check medication safety during pregnancy if you're managing any conditions.
The exception
Do not eat a pack past its use-by date or one that has been out of the fridge. The UK supermarket ham packs we checked say to eat within 2 days of opening (and by the use-by date if that is sooner). Cold cured meats such as Parma ham and salami must be cooked until steaming hot first.
What the NHS says now, in its own words
Many pages, including an earlier version of this one, say cooked ham is 'safe' in pregnancy. The current NHS foods-to-avoid page (last reviewed 15 June 2026) is more precise. It does not put cooked ham on the avoid list; it puts it under foods to be careful with:
| NHS wording | What it means for ham |
|---|---|
| 'any processed, cold pre-cooked meats, such as ham or chicken – keep chilled and eat before the use-by date' | Cold sliced ham is allowed, but only if it has been kept chilled and is within its use-by date |
| 'pre-packaged sandwiches and salads containing meat – keep them chilled and eat them before the use-by date' | A ham sandwich from a shop follows the same rule |
| 'some ready-to-eat foods, like pre-packaged sandwiches and salads, may also contain listeria bacteria' | This is the reason for the care: ready-to-eat food is not cooked again before you eat it |
| 'cold cured meats such as salami, pepperoni, chorizo and prosciutto – should be cooked until steaming hot before eating' | Cured ham (Parma, Serrano) is a different group; see Parma ham |
What three UK ham packs tell you to do
Packs give the practical rule the NHS leaves to the label. We read three supermarket product pages on 28 October 2026:
| Pack | Storage wording | Freezing |
|---|---|---|
| Tesco Eastmans Wafer Thin Cooked Ham Slices 125g (described as 'cured and cooked reformed ham') | 'Keep refrigerated.' 'Once opened, consume within 2 days and by use by date shown.' | Not suitable for freezing |
| Tesco Prime Cuts Honey Roast Ham 6 Slices 120g | 'Keep refrigerated. Once opened, consume within 2 days and by use by date shown.' | Not suitable for freezing |
| M&S British Wafer Thin Ham 125g (via Ocado) | 'Keep refrigerated 0°C to +5°C. Once opened, eat within 2 days (and by date mark shown).' | Not suitable for home freezing |
All three say the same thing: the earlier of 2 days after opening and the printed date. These are three packs, not every brand, so read yours. See also how long cooked ham lasts and freezing cooked ham.
Use-by date or 'within 2 days'? Whichever comes first
| Pack use-by date | Opened | Eat by |
|---|---|---|
| Friday | Monday | Wednesday (2 days after opening is earlier) |
| Tuesday | Monday | Tuesday (the use-by date is earlier) |
| Friday | Thursday | Friday (the use-by date is earlier) |
Worked examples of the rule printed on the three packs above. A pack that is still sealed is judged by the use-by date alone.
Which kind of ham are you looking at?
| Ham | In pregnancy | Why |
|---|---|---|
| Pre-packed sliced cooked ham, in date, kept in the fridge | Allowed: keep chilled, eat before the use-by date | NHS 'be careful with' wording |
| Ham sandwich or wrap from a shop | Allowed on the same terms | NHS: pre-packaged sandwiches containing meat |
| Ham from a deli counter | Not covered by the NHS page we read | The Bump (US) flags shared slicers as a cross-contamination risk for cheese. Ask how long since it was sliced, or choose a sealed pack (our suggestion) |
| Home-cooked roast gammon or Christmas ham | Fine while fresh; chill promptly and finish within 2 days | NHS Forth Valley leftovers sheet: cool and chill within about an hour, eat within 2 days, reheat until steaming hot, only once |
| Hot ham (in a pasta bake, on pizza, steaming hot) | Fine: heated until steaming hot | More cautious than the NHS requires |
| Parma, Serrano and other cured ham | Cook until steaming hot first | NHS: cold cured meats |
Why US pages sound stricter
US articles often say to avoid deli meat or heat it. The Bump (28 May 2024) says the safest thing is to avoid deli meats and, if you eat them, heat to an internal temperature of 165°F until steaming. Expectful (updated 30 April 2026) separates sliced deli ham from roast ham and says pre-packaged or deli-counter slices are more likely to host bad bacteria. Neither page discusses UK guidance. The NHS does not ask for ham to be heated, but heating until steaming hot is a more cautious option that is consistent with what the NHS asks for cured meats.
What we left out
Expectful says ham has high nitrates and nitrites and suggests not eating it regularly, citing a study; we have not opened that study and found no NHS statement on nitrates in pregnancy, so we do not give a number. Salt and processed-meat limits for the general population are a separate topic.
