Mozzarella in Pregnancy — Pizza Nights Without the Panic

Mozzarella might be the most-loved cheese of pregnancy — stretchy pizza slices, lasagne, grilled sandwiches, caprese salads. The good news: you usually don’t need to give it up.

Most mozzarella you meet in supermarkets and restaurants is made from pasteurised milk, and any mozzarella that’s cooked until hot and melty is safe. [2] [4]

There are just a few details to pay attention to:

✔ Pasteurised mozzarella = safe ✔ Cooked mozzarella (pizza, pasta bakes) = safe ❌ Unpasteurised mozzarella = avoid

This guide breaks down fresh vs low-moisture, buffalo vs cow’s milk, eating out rules, and how to store it safely at home.

Quick Take (TL;DR)

  • Pasteurised mozzarella is pregnancy-safe, both fresh and cooked. [2]
  • Pizza with melted mozzarella is safe because it’s baked until hot. [4]
  • Traditional unpasteurised buffalo mozzarella is not recommended — check labels carefully. [3]
  • Store fresh mozzarella chilled, in brine, and eat within 1–2 days of opening.
  • If the label doesn’t state “pasteurised” and staff can’t confirm, choose a safer cheese instead.

What Exactly Is Mozzarella?

Mozzarella is a semi-soft, mild cheese originally from Italy. It’s made using a “pasta filata” or ‘stretched curd’ process, which gives it that stretchy, melty texture.

Common types you’ll see:

  • Fresh mozzarella balls — stored in brine or whey.
  • Low-moisture mozzarella — blocks or pre-shredded bags for pizza.
  • Buffalo mozzarella — traditionally made from buffalo milk.
  • Mozzarella sticks — breaded and fried (usually from low-moisture cheese).

All of these are safe in pregnancy when they are pasteurised and properly stored — and extra safe when cooked.

Safety Science — Why Pasteurisation Matters Less Here (But Still Counts)

Soft, high-moisture cheeses made from unpasteurised milk can sometimes harbour Listeria monocytogenes, a bacteria that can cause severe illness in pregnancy. [1]

The key points with mozzarella:

  • Most commercial mozzarella is pasteurised, especially outside small artisan producers. [2]
  • Fresh mozzarella is higher moisture, so it still needs good refrigeration and quick use.
  • Cooking mozzarella until hot and melted kills Listeria if it was present. [4]
  • Unpasteurised buffalo mozzarella can be risky, especially when eaten cold.

That’s why official advice usually lists mozzarella (made from pasteurised milk) as one of the cheeses that is safe in pregnancy, unlike many soft mould-ripened cheeses. [2]

Nutrition Snapshot — Mild, Protein-Rich Comfort

Mozzarella is mild in flavour but powerful in nutrition — especially as a source of protein and calcium.

Nutrient (per 100 g) Approx. Pregnancy Note
Calories≈ 280 kcalModerately energy-dense.
Protein≈ 18–20 gSupports baby’s growth and your muscle mass.
Fat≈ 17–20 gContributes to satiety; watch portion size if you’re balancing weight.
Calcium≈ 400–500 mgGreat for bones and teeth.
Sodium≈ 400–600 mgLess salty than some cheeses; still worth moderating if you have high BP.

Portion & Balance — How Much Mozzarella Is Reasonable?

You don’t need to fear mozzarella — you just want it as part of a balanced plate, not the entire story.

  • Caprese salad: ~30–50 g mozzarella with tomato and basil.
  • Pizza: 1–2 slices with salad on the side (instead of the whole pie solo).
  • Pasta bake: modest mozzarella topping plus vegetables and lean protein.

Think of mozzarella as a comfort-add that brings joy and calcium, balanced with fibre, vegetables and lean protein.

Trimester Tips — Mozzarella Across Pregnancy

1st Trimester

If nausea is strong, simple foods like plain pizza with mozzarella or grilled cheese can feel comforting. Just keep an eye on how greasy toppings make you feel.

2nd Trimester

Use mozzarella to add protein to wraps, quesadillas and pasta bakes. Pair with vegetables to keep digestion smooth.

3rd Trimester

If heartburn flares, avoid very heavy, greasy cheese meals at night — but lighter mozzarella portions with salads or whole grains are usually well tolerated.

Myths & Facts

  • Myth: “All soft cheeses are unsafe in pregnancy.”
    Fact: Soft cheeses made from pasteurised milk like mozzarella are considered safe. [2]
  • Myth: “Pizza cheese is always risky.”
    Fact: Mozzarella on pizza is cooked at high temperature until melted — that makes it safe. [4]
  • Myth: “Buffalo mozzarella is always dangerous.”
    Fact: Pasteurised buffalo mozzarella is safe; the concern is with traditional raw-milk versions. [3]

Pregnancy FAQ — Mozzarella

Is mozzarella safe during pregnancy?

Yes — mozzarella made from pasteurised milk is considered safe in pregnancy. This includes most supermarket fresh mozzarella, blocks and shredded cheese. [2]

Is mozzarella on pizza safe when pregnant?

Yes. Mozzarella on pizza is heated to high temperatures until melted and bubbling, which makes it safe, especially when it also starts from pasteurised cheese. [4]

Is buffalo mozzarella safe in pregnancy?

Buffalo mozzarella is safe only if made from pasteurised milk. Some traditional buffalo mozzarella is unpasteurised, so you should always check the label or ask the restaurant. [3]

Can I eat fresh mozzarella balls from the fridge?

Yes, if they are made from pasteurised milk, kept refrigerated at ≤4 °C, and eaten within 1–2 days of opening. [2]

Do I need to avoid unpasteurised mozzarella completely?

It’s safest to avoid unpasteurised soft cheeses in pregnancy. If you are unsure, treat the cheese as unsafe and choose a pasteurised option instead. [1]
