Is Soft-Serve Ice Cream Safe During Pregnancy?

Quick Answer

Soft-serve ice cream is one of those foods that sparks endless debate in pregnancy forums—and for good reason. The concern is not the ice cream itself, but the machines that dispense it. When properly maintained, soft-serve from reputable sources carries minimal risk. However, poorly cleaned machines can harbour Listeria monocytogenes, a bacteria particularly dangerous during pregnancy.

So, can you enjoy that McDonald's cone or Dairy Queen Blizzard? Let us break down the real risks, what the science says, and how to make an informed decision that works for you.

Understanding the Listeria Concern

Before we dive into soft-serve specifically, it helps to understand why Listeria is such a concern during pregnancy. Listeria monocytogenes is a hardy bacterium with an unusual superpower: it can grow at refrigerator temperatures where most other bacteria cannot survive.

Here is the important perspective: while listeriosis is serious, it remains rare. The NHS estimates that only about 1 in 12,000 pregnant women in the UK will develop listeriosis annually. The question becomes: how much does soft-serve contribute to this risk?

The Soft-Serve Machine Problem

The reason soft-serve gets singled out—while regular ice cream gets a pass—comes down to temperature and equipment. Here is what happens inside a soft-serve machine:

1. Liquid mix (containing pasteurised milk, sugar, and flavourings) is poured into a hopper
2. The machine churns and aerates the mix while cooling it to approximately -6°C to -4°C
3. This temperature is warmer than a typical freezer (-18°C), creating conditions where Listeria could survive if present
4. Internal components—tubes, nozzles, and dispensing mechanisms—can develop biofilms if not thoroughly cleaned

A 2019 study published in the International Journal of Food Microbiology found that soft-serve machines sampled across various food service outlets showed bacterial contamination in approximately 12% of samples—though Listeria specifically was found in less than 1% of properly maintained equipment.

The Real-World Risk: Putting It in Perspective

Let us be honest: the internet has made many pregnant women terrified of soft-serve. But what does the actual data show?

The 2023 hospital outbreak is particularly instructive: a milkshake machine on a hospital ward—where vulnerable patients were served—was linked to listeriosis cases. This was an unusual setting with potentially immunocompromised patients and possibly inconsistent cleaning schedules. It does not reflect the typical experience at a busy high-street chain.

A Tale of Two Ice Creams: Risk Comparison

Emma, 32 weeks pregnant, stands in a shopping centre debating her options. She can choose soft-serve from the McDonald's kiosk or grab a pre-packaged Magnum from the freezer cabinet. What is the actual difference in risk?

What the Official Guidance Says

Interestingly, official guidance varies by country, reflecting different risk tolerances and regulatory environments:

• UK NHS: Does not specifically prohibit soft-serve but recommends being "cautious" with machine-dispensed products
• Food Standards Australia/New Zealand: Advises pregnant women to avoid soft-serve ice cream entirely
• US CDC: Does not single out soft-serve but recommends avoiding foods from establishments with poor hygiene
• Health Canada: Lists soft-serve among foods to "be cautious" about during pregnancy

Notice the spectrum: some countries recommend avoidance, others suggest caution. This reflects the low absolute risk but potentially serious consequences if contamination does occur.

Making Your Own Decision

Pregnancy food safety is deeply personal. Some women feel comfortable with soft-serve from major chains; others prefer to avoid it entirely. Neither approach is wrong—it depends on your individual risk tolerance and peace of mind.

Questions to Ask Yourself

• How important is this particular treat to me right now?
• Is this a well-known chain with strict corporate hygiene standards?
• Does the outlet appear clean and well-maintained?
• Is there a safer alternative that would satisfy my craving just as well?
• Will I worry about it afterward? (Stress is not good for pregnancy either!)

If You Choose Soft-Serve: Practical Tips

Should you decide to indulge, here are evidence-based ways to minimise any residual risk:

• Choose busy locations: High turnover means the mix is constantly being replenished, reducing the time bacteria could grow
• Go to reputable chains: McDonald's, Dairy Queen, and similar chains have strict corporate cleaning protocols
• Avoid toppings from communal containers: Sprinkles, sauces, and crushed biscuits sitting at room temperature can harbour bacteria
• Eat it immediately: Do not let soft-serve sit at room temperature; consume it while frozen
• Trust your instincts: If something looks or smells off, walk away

Safer Alternatives That Hit the Spot

If you want the creamy frozen treat experience without any worry, these options provide complete peace of mind:

• Ben and Jerry's or Häagen-Dazs from the freezer aisle: Factory-sealed and stored at safe temperatures
• Frozen fruit bars and lollies: Individually sealed, refreshing, and lower in calories
• Greek yogurt frozen bark: Make at home with pasteurised yogurt, fruit, and a bit of honey
• Frozen banana "nice cream": Blend frozen bananas for a creamy, dairy-free treat
• Magnum or Cornetto: Pre-packaged and perfectly safe

What If I Already Ate Soft-Serve?

First: do not panic. Millions of pregnant women consume soft-serve without incident. Listeriosis symptoms typically appear within 1-4 weeks and include:

• Fever and flu-like symptoms
• Muscle aches
• Nausea or diarrhoea
• Headache and stiff neck (in severe cases)

If you develop these symptoms—particularly fever—contact your GP or midwife. They can arrange blood tests if needed. But remember: the overwhelming likelihood is that you will be absolutely fine.

Common Questions

• Is McDonald's McFlurry safe during pregnancy? McDonald's has rigorous cleaning protocols for their soft-serve machines. Many pregnant women consider this an acceptable risk, though it remains a personal choice.
• What about frozen yogurt from machines? Same considerations as soft-serve ice cream—it depends on machine hygiene.
• Can I eat soft-serve in my third trimester? The guidance remains consistent throughout pregnancy. There is no "safer" trimester for soft-serve.
• Is gelato safer than soft-serve? Traditional gelato scooped from a freezer cabinet is generally considered safer because it is kept at properly frozen temperatures without machine dispensing.
• What about making soft-serve at home? Homemade soft-serve using a Ninja Creami or similar device with pasteurised ingredients is safe—you control the hygiene completely.

The Bottom Line

Soft-serve ice cream during pregnancy is not the clear-cut "avoid at all costs" that some sources suggest. The risk is real but very small, especially from well-maintained machines at reputable outlets. The decision ultimately comes down to your personal comfort level.

If soft-serve brings you joy and you choose a clean, busy, reputable source—enjoy it. If the uncertainty causes anxiety, there are plenty of equally delicious pre-packaged alternatives that eliminate the concern entirely.

Either way, you are making a thoughtful, informed choice—and that is exactly what good prenatal care looks like.
