Can I Eat Mozzarella in Pregnancy? Complete Guide
Mozzarella is a pizza-night staple and a caprese-salad essential, and it's understandable to want reassurance before piling it on. The reassuring answer is that mozzarella is one of the more straightforward soft cheeses to navigate in pregnancy — most of what's sold in the UK is pasteurised and perfectly safe.
Why mozzarella is generally safe
As with other soft cheeses, the question that matters most for pregnancy safety is whether the milk used was pasteurised, since pasteurisation eliminates the risk of listeria contamination that unpasteurised dairy can occasionally carry.
- Standard block or grated mozzarella sold in UK supermarkets, typically used for pizza and cooking, is made with pasteurised cow's milk and is safe.
- Fresh mozzarella balls (the kind packaged in a bag of liquid, often used in caprese salad) are also usually pasteurised in the UK — check the label to confirm.
- Buffalo mozzarella is traditionally made from water buffalo milk and can occasionally be unpasteurised, particularly with imported or artisan products, so it's worth double-checking the label specifically for buffalo varieties.
- Smoked mozzarella and other variants follow the same rule — pasteurised is safe, and the label will confirm this either way.
Cooking mozzarella removes any doubt
If you're ever uncertain about a particular product, cooking it thoroughly is an easy way to remove any residual risk, since heat destroys listeria bacteria.
- On pizza, baked until bubbling and golden, mozzarella is unquestionably safe regardless of the starting product.
- In a baked pasta dish, lasagne, or melted into a toastie, thorough cooking has the same effect.
- If you're making a cold dish like caprese salad and want extra reassurance, choose a well-known UK supermarket brand and check the pasteurisation statement on the pack.
A few practical tips
- Keep mozzarella refrigerated and use it within its use-by date — general food hygiene matters just as much as the pasteurisation question.
- If you're eating out, restaurants in the UK are required to use safe ingredients, but if you have any doubt about a dish containing fresh, unheated mozzarella, it's fine to simply ask.
- Mozzarella is a reasonable source of calcium and protein, both useful nutrients in pregnancy, so there's no nutritional reason to avoid it if it's safe for you.
Frequently Asked Questions
Is mozzarella safe in pregnancy?
Yes. Mozzarella made with pasteurised milk — which covers the vast majority of mozzarella sold in UK supermarkets, including standard block mozzarella and fresh mozzarella balls — is safe to eat throughout pregnancy. As always, check the label if you're unsure, particularly with imported or specialist products.
Can I eat buffalo mozzarella when pregnant?
Yes, provided it's pasteurised, which most UK-sold buffalo mozzarella is. Because buffalo mozzarella is more likely than standard cow's milk mozzarella to be an imported or artisan product, it's worth taking a moment to check the label specifically states "pasteurised," or cook it thoroughly if you're unsure.
Is mozzarella on pizza always safe, even from a takeaway?
Yes — cooking mozzarella at pizza-oven temperatures destroys any listeria bacteria that might theoretically be present, so hot, freshly baked pizza is safe regardless of whether the cheese used was pasteurised to begin with. The main caution around soft cheese applies to cold, unheated servings rather than cooked dishes.
