Can I Eat Ham While Pregnant?
Updated June 2026 · based on NHS and official food-safety guidance
The NHS says cold, pre-packed cooked ham (the standard sliced supermarket kind) is safe in pregnancy, while the CDC and FDA advise heating all deli and lunch meats, including ham, to 165F (74C) or until steaming hot to kill any listeria. Cold cured ham such as prosciutto, parma or serrano is the one to be careful with, because it is air-dried rather than cooked and can carry the toxoplasmosis parasite or listeria. Either way, ham that is cooked through and piping hot is safe everywhere.
Ham is one of those foods where the safe answer depends on which type you mean and where you live. A slice of cooked ham in a sandwich is not the same as a sheet of cured prosciutto on a board, and UK and US health bodies draw the line in slightly different places. This guide breaks down each kind of ham, explains the listeria and toxoplasmosis risks behind the rules, and shows you exactly how to make any ham safe, so you can stop second-guessing your lunch. For a specific product, the Muka app gives you a verdict in 3 seconds by barcode scan or photo.
Which hams are safe during pregnancy?
| Type of ham | Verdict | Why |
|---|---|---|
| Pre-packed cooked ham, eaten cold (UK) | Safe | The NHS lists cold, pre-packed cooked ham as safe in pregnancy. It is fully cooked and sealed, so listeria risk is low. |
| Deli or lunch ham, eaten cold (US) | In moderation | The CDC and FDA advise heating deli ham to 165F or until steaming hot before eating, because it can carry listeria that grows even in the fridge. |
| Ham cooked or reheated until steaming hot | Safe | Heating to 165F (74C) kills listeria and the toxoplasmosis parasite, making any ham, including cured types, safe to eat. |
| Cold cured ham: prosciutto, parma, serrano, jamon | Avoid | These are air-dried, not cooked, so they may carry the toxoplasmosis parasite or listeria. The NHS says eat them only if cooked thoroughly, for example on a hot pizza. |
| Honey-roast or wafer-thin cooked ham, eaten cold | In moderation | Safe cold under NHS guidance if pre-packed and cooked; in the US, heat it until steaming first as with any deli meat. |
| Ham from an open deli counter, sliced to order | In moderation | Shared slicers can spread listeria between products, and the CDC links deli counters to outbreaks. Heating it until steaming removes the risk. |

Is cooked ham safe to eat cold during pregnancy?
In the UK, yes. The NHS lists cold, pre-packed cooked ham as safe to eat in pregnancy because it is fully cooked and sealed. In the US, the CDC advises heating deli ham, including cooked ham, until steaming hot first to remove any listeria risk before eating it.
Can I eat a ham sandwich while pregnant?
Yes, if you choose the ham carefully. A sandwich made with pre-packed cooked ham is fine in the UK. To be safest, especially in the US, heat the ham until steaming hot and let it cool, or pick freshly cooked, hot ham rather than cold cured ham like prosciutto or parma.
Why is cured ham like prosciutto different from cooked ham?
Cured ham such as prosciutto, parma and serrano is preserved by air-drying and salting rather than cooking. Because it is never heated, it can carry the toxoplasmosis parasite or listeria. The NHS says to eat these only if they are cooked thoroughly, such as crisped on a hot pizza.
I ate cold cured ham while pregnant, should I worry?
Try not to panic. The risk from a single serving is very low, and most people have no problems at all. Listeria and toxoplasmosis infections in pregnancy are rare. Just watch for fever, aches or flu-like symptoms over the next few weeks, and contact your midwife or doctor if you feel unwell.
How do I make ham safe to eat in pregnancy?
Heat it until it is steaming hot all the way through, reaching 165F (74C) if you use a thermometer. This kills listeria and the toxoplasmosis parasite. Cooked ham on a hot pizza, in a toastie, or stirred into a hot dish is safe for any type, including cured ham.
