Yes, pregnant women can eat potato salad, but safety depends heavily on preparation and storage — homemade versions are generally considered safe.
Potato salad seems like a simple side dish, but during pregnancy the question of safety can feel surprisingly complicated. The confusion often starts with the mayonnaise, since raw eggs are a known salmonella risk. But for potato salad, there’s a different concern that gets less attention.
The short answer is yes — with a big caveat. Homemade potato salad made with pasteurized ingredients and kept properly refrigerated is generally considered safe. Store-bought or deli-prepared versions are a different story. Here’s what to know before you take a scoop.
Why Deli Potato Salad Is a Riskier Choice
The CDC’s food-safety guide for pregnancy lists premade deli salads — including potato salad, coleslaw, tuna salad, chicken salad, and egg salad — as a “Riskier Choice” for pregnant women. The agency recommends choosing homemade versions of these salads instead.
Listeriosis is the main concern. Pregnant women are about 10 times more likely to get listeriosis than the general population, according to the FDA. The infection can be serious, and it often comes from foods that are ready-to-eat and stored cold for long periods — exactly the conditions in a deli case or packaged salad bag.
That doesn’t mean every store-bought potato salad is contaminated. But the risk is high enough that major health authorities advise avoiding them entirely during pregnancy.
Why People Worry About Mayo — And Why That’s Not the Full Picture
Many people assume the problem is the mayonnaise, because of the old raw-egg warning. But commercial mayonnaise is made with pasteurized eggs and is actually quite low-risk. The real issue is something else: once potatoes are cooked and mixed with dressing, they sit at temperatures that can allow listeria to grow if not kept cold.
Here’s what makes a potato salad safe during pregnancy:
- Pasteurized ingredients: Use store-bought mayo or pasteurized egg products. Homemade mayo with raw eggs is not recommended.
- Freshly cooked potatoes: Cook potatoes just before making the salad and cool them quickly if you plan to refrigerate.
- Immediate refrigeration: Keep the salad at or below 40°F. Don’t let it sit out longer than 2 hours.
- Short storage: Eat homemade potato salad within 3 to 4 days. The longer it sits, the more chance bacteria have to multiply.
- Reheating as an option: If you want to be extra cautious, you can reheat the potato salad until steaming hot — the NHS notes this kills listeria — though that changes the texture significantly.
Listeria: The Real Concern for Pregnant Women
Listeria monocytogenes is a bacterium that can survive and even grow at refrigerator temperatures. The CDC’s food safety page for pregnancy highlights that CDC deli salads risk as a common source. The FDA adds that raw or processed vegetables, unpasteurized dairy, and ready-to-eat foods like premade salads are considered high-risk for listeria contamination during pregnancy.
Most people who eat listeria-contaminated food don’t get sick. But during pregnancy, the immune system shifts in ways that make infection more likely. Symptoms of listeriosis can be mild — fever, muscle aches, nausea — but the infection can also lead to miscarriage, preterm labor, or serious illness in newborns.
| Food Type | Risk Level for Pregnancy | Why |
|---|---|---|
| Homemade potato salad (pasteurized ingredients, fresh) | Low risk | Prepared and stored safely |
| Store-bought deli potato salad (cold case) | Higher risk | Stored for days; may not be held cold enough |
| Pre-packaged refrigerated salads (bagged) | Higher risk | 8 US listeriosis outbreaks linked to packaged salads (2015–2024) |
| Homemade potato salad left out >2 hours | Higher risk | Bacteria can multiply at room temperature |
| Reheated potato salad (steaming hot) | Low risk | Heat kills listeria |
This table shows how preparation and handling shift the risk. The key takeaway: fresh and cold is safe — old and warm is not.
How to Safely Enjoy Potato Salad During Pregnancy
If you’re craving potato salad, homemade is your best bet. By making it yourself, you control every step. Here’s a safe approach:
- Cook the potatoes thoroughly. Boil or bake them until tender — raw or undercooked potatoes aren’t the issue, but it ensures even cooking.
- Use pasteurized ingredients. Choose commercial mayonnaise or pasteurized eggs for the dressing. Avoid raw-egg homemade mayo.
- Cool potatoes quickly. If you aren’t mixing the salad immediately, spread the cooked potatoes on a tray and refrigerate them before combining.
- Refrigerate within 2 hours. Once the salad is assembled, put it in the fridge. Don’t let it sit out during a barbecue.
- Eat within 3 to 4 days. After that, risks increase. If the salad smells off or has been out longer than 2 hours total, toss it.
Some women find that adding a splash of vinegar or lemon juice to the dressing may help lower pH slightly, but this isn’t a substitute for proper refrigeration. The most reliable safety measure is keeping the salad cold.
What About Store-Bought Packaged Salads?
Packaged salads — the kind sold in plastic tubs from the refrigerated section — are prepared in large facilities and may sit in distribution centers or on shelves for days. The NHS (UK) explicitly advises people to avoid ready-prepared dressed salads like coleslaw or potato salad during pregnancy, because cooked-chilled foods can carry listeria risk. The NHS adds that if you do have such a salad, you can make it safer by reheating it until steaming hot throughout — though that changes the texture.
The NHS avoid dressed salads guidance is consistent with the CDC’s recommendation to view deli salads as a riskier choice. For pregnant women, the safest plan is to skip the store-bought versions and make your own. If you do buy a packaged salad, check the expiration date, ensure it has been continuously refrigerated, and eat it the same day you open it.

|---|---|
| CDC | Avoid premade deli salads; choose homemade |
| FDA | Avoid high-risk foods including ready-to-eat salads |
| NHS (UK) | Avoid ready-prepared dressed salads |
| NSW Food Authority (Australia) | Wash ingredients just before making; refrigerate and use within a day |
The Bottom Line
Potato salad can be part of a healthy pregnancy diet if you prepare it yourself with pasteurized ingredients and keep it properly refrigerated. Store-bought and deli versions are best avoided due to the established listeria risk. The key is treating potato salad as a fresh food — not something that can sit out or linger in the fridge for days.
If you have pregnancy-specific food allergies or conditions like gestational diabetes, your obstetrician or a registered dietitian can help you adjust your recipe to fit your needs, from the type of potatoes to the dressing ingredients you choose.
