Is Mozzarella Safe During Pregnancy? Fresh, Buffalo and Burrata

Mozzarella causes more unnecessary worry than almost any cheese, and the reason is a category error. It is soft, it is wet, it comes floating in liquid, and the pregnancy cheese warning is about "soft cheese". So people put two and two together and get five.

The warning was never really about softness. Here is what it is actually about, and why mozzarella almost always sits on the right side of it.

Why Mozzarella Is Safe

The pregnancy cheese rule exists because of Listeria monocytogenes, which matters in pregnancy because you are roughly ten times more susceptible than usual and it can cross the placenta.

But listeria gets into cheese in one main way: unpasteurised milk. Pasteurisation heats milk enough to kill it before the cheese is even made. So the genuine question for any cheese is not "is it soft" but "was the milk pasteurised".

The second factor is the cheese's own environment. Listeria prefers moist, low-acid conditions, which is why soft mould-ripened cheeses like brie and camembert get named specifically. Mozzarella is moist, but it is also acidic from the culturing process, and crucially it is made from pasteurised milk in virtually every commercial case.

Put those together and mozzarella lands firmly in the safe column. Our complete pregnancy cheese guide maps the whole aisle by the same logic.

Fresh, Buffalo, Burrata and Pizza: Type by Type

Fresh mozzarella (the balls in water). Safe when pasteurised, which supermarket fresh mozzarella essentially always is. The water it sits in is brine, not a hygiene problem. Once opened, treat it like any fresh dairy: keep it cold and use it within a couple of days rather than letting it sit for a week.

Buffalo mozzarella (mozzarella di bufala). Safe when pasteurised, and most sold in UK and US supermarkets is. This is the one where imported artisan versions occasionally are not, so it is the label most worth glancing at. Italian DOP buffalo mozzarella can be made with raw milk in some traditional productions.

Burrata. Safe when pasteurised. Burrata is mozzarella wrapped around cream and curd, so the same rule applies to both parts. It has a very short shelf life, so freshness matters more here than with most cheeses. Buy it close to the date and eat it that day.

Low-moisture and grated mozzarella. The block or bag kind for cooking. Safe, pasteurised, and lower moisture means an even less hospitable environment for bacteria.

Mozzarella on pizza, in lasagne, on garlic bread. Safe twice over. Pasteurised to begin with, then cooked to well above the temperature that kills listeria. There is no pregnancy reason to avoid a margherita.

Smoked mozzarella (scamorza). Safe when pasteurised, same as the rest.

The Label Check That Settles It

Turn the packet over and look for the word pasteurised in the ingredients. That is the entire check, and it takes three seconds.

In the UK, look for "pasteurised cow's milk" or "pasteurised buffalo milk". In the US, pasteurisation is required for most cheeses aged under 60 days, which includes all fresh mozzarella, so supermarket mozzarella is pasteurised by law. If a label genuinely says raw milk or unpasteurised, that is your cue to cook it or choose another.

Where to be a little more careful: deli counters, farmers markets, Italian delis and cheese shops, where artisan and imported versions live. Not because those are bad, but because the label is often not in front of you. Asking "is this pasteurised?" is a completely normal question that any decent cheesemonger answers instantly.

The Nutrition Case for Eating It

Mozzarella is quietly one of the more useful cheeses in pregnancy, which is worth knowing once the safety question is settled.

A 50g serving, roughly half a ball of fresh mozzarella, gives you around 10g of protein and 250mg of calcium, against a daily calcium target of about 1,000mg. That is a genuinely meaningful contribution from something you would eat for pleasure anyway.

It is also comparatively low in salt for a cheese, which matters in the third trimester when swelling is common. Compare it to halloumi, which is delicious but carries three times the sodium, or feta, which is also brined and salty. If you are choosing a cheese to eat regularly while pregnant, mozzarella is one of the better picks.

And it is a practical answer to first trimester meat aversion. Caprese salad, a margherita pizza, or mozzarella with crackers are all high-protein meals that require no meat and very little effort, which matters on the days when chicken is unthinkable. Our meat aversion protein guide has more of these.

Common Questions

Where Mozzarella Sits Against Every Other Cheese

Since the mozzarella question almost always arrives attached to a wider cheese question, here is the whole aisle sorted by the rule that actually matters.

• Always fine, no checking needed: every hard cheese. Cheddar, parmesan, gouda, manchego, pecorino, and hard blue cheeses like stilton. Ageing and low moisture make these inhospitable.
• Fine when pasteurised, which is nearly always: mozzarella, ricotta, feta, cream cheese, cottage cheese, halloumi, paneer, mascarpone.
• Skip cold, safe cooked until steaming: soft mould-ripened cheeses. Brie, camembert, chevre with a white rind, and soft blue cheeses like gorgonzola or roquefort.
• Genuinely avoid: anything unpasteurised that you are not going to cook.

Notice that mozzarella sits in the second group alongside most of the cheeses people worry about, and that the group people actually need to be careful with is small. The mental shortcut worth keeping is raw milk, not soft texture.

Eating Out: The Only Situations Worth a Thought

Restaurant mozzarella is nearly always the commercial pasteurised kind, and anything that arrives hot is settled regardless. Three situations deserve half a second of thought.

An upmarket Italian restaurant advertising imported buffalo mozzarella is the one place you might genuinely encounter an unpasteurised version, precisely because they are sourcing traditionally. Ask, or order it in something cooked.

A caprese or antipasti platter that has been sitting out at a buffet or a long lunch. The issue there is time at room temperature rather than the cheese itself, which is the same reasoning covered in our pregnancy buffet guide.

A deli counter making fresh mozzarella in house. Lovely, and worth asking about the milk, since small producers occasionally use raw milk deliberately.

Everywhere else, from pizzerias to supermarket sandwiches to your own kitchen, mozzarella is simply fine.
