Can I Eat Hot Dogs While Pregnant?
Updated June 2026 · based on NHS and official food-safety guidance
Hot dogs are pre-cooked, but they can pick up Listeria after packaging, and this germ keeps growing even in the fridge. Heating each hot dog until it is steaming hot (165°F / 74°C inside) kills Listeria, which in pregnancy can cause miscarriage, stillbirth or premature birth. If you cannot reheat one thoroughly, it is safest not to eat it cold or lukewarm.
Craving a hot dog at a barbecue or game and wondering if it is off-limits? The good news is you do not have to skip them. The single thing that matters is temperature: a hot dog served steaming hot is fine, while one eaten cold or barely warm from the packet is the one to avoid. Below you will find clear US and UK guidance, a quick verdict table, and answers to the questions pregnant people ask most, including what to do if you have already eaten one cold. For a specific product, the Muka app gives you a verdict in 3 seconds by barcode scan or photo.
Hot dogs in pregnancy: safe vs. avoid
| Type | Verdict | Why |
|---|---|---|
| Hot dog reheated until steaming hot (165°F/74°C) | Safe | Thorough reheating kills any Listeria, so a piping-hot hot dog is considered safe in pregnancy. |
| Boiled, grilled or microwaved until piping hot throughout | Safe | Boiling, grilling or microwaving until steaming all the way through reaches the temperature needed to destroy Listeria. |
| Cold or lukewarm hot dog straight from the packet | Avoid | Eaten cold, a hot dog can carry Listeria that has grown in the fridge; pregnant people are far more vulnerable to it. |
| Hot dog at a stand or fair (temperature unknown) | In moderation | Only eat it if it is served steaming hot; if it is warm or you cannot tell, it is safer to skip it. |
| Cold cured sausage (chorizo, salami) on a hot dog | In moderation | NHS flags cold cured meats for toxoplasmosis; cook them thoroughly first or choose a freshly cooked topping. |
| Plant-based / veggie hot dog served hot | Safe | Meat-free hot dogs avoid the meat-borne risks; reheat until hot and follow the pack instructions as usual. |

Can I eat hot dogs while pregnant?
Yes, as long as each hot dog is reheated until it is steaming hot, around 165°F (74°C) inside. Hot dogs can carry Listeria, which grows even in the fridge, so heating them thoroughly is what makes them safe. Avoid eating them cold or only lukewarm from the packet.
Why are hot dogs a listeria risk in pregnancy?
Although hot dogs are pre-cooked, they can be contaminated with Listeria after packaging, and this germ keeps multiplying at fridge temperatures. In pregnancy, listeriosis is far more likely and can cause miscarriage, stillbirth or premature birth. Heating until steaming hot reliably kills the bacteria.
I ate a cold hot dog while pregnant, should I worry?
Try not to panic, as Listeria infection from a single cold hot dog is rare with today's food handling. Symptoms can take anywhere from a few days up to several weeks to appear, so watch for flu-like signs such as fever, chills, headache or aches, and contact your midwife or doctor if any develop so they can advise you.
What temperature should hot dogs be for pregnancy?
Heat each hot dog until it is steaming hot all the way through, reaching an internal temperature of about 165°F (74°C). Boiling, grilling or microwaving until piping hot all work. If you cannot get it that hot, US guidance says it is safer not to eat it.
Are hot dogs safe in pregnancy in the UK?
The NHS does not single out hot dogs but advises cooking sausages and pork thoroughly, so heat them until piping hot. It also flags cold cured meats like chorizo and salami for toxoplasmosis, so cook those toppings well or choose a freshly cooked alternative instead.
