Pasteurized mozzarella is safe during pregnancy, while unpasteurized varieties pose health risks.
Understanding Mozzarella and Pregnancy Safety
Mozzarella is a beloved cheese known for its creamy texture and mild flavor. But when pregnancy enters the picture, questions about food safety arise quickly. The main concern with mozzarella during pregnancy centers on whether it’s made from pasteurized milk or not. Pasteurization is a heat treatment process that kills harmful bacteria like Listeria monocytogenes, which can cause listeriosis—a dangerous infection for pregnant women and their babies.
Listeriosis can lead to miscarriage, premature birth, or serious illness in newborns. Because mozzarella comes in many forms—fresh, shredded, smoked—knowing which types are safe is crucial. Fresh mozzarella sold commercially in most developed countries is typically made from pasteurized milk, making it safe to eat during pregnancy. However, homemade or imported fresh mozzarella might not always be pasteurized.
Why Pasteurization Matters for Pregnant Women
Pregnancy weakens the immune system slightly to accommodate the growing fetus. This makes expecting mothers more vulnerable to infections like listeriosis. Pasteurization ensures that any harmful bacteria present in raw milk are destroyed before the cheese reaches your plate.
Cheeses made from unpasteurized milk carry a higher risk of contamination. Pregnant women should avoid soft cheeses unless they are explicitly labeled as pasteurized. Mozzarella falls into the soft cheese category when fresh and unripened, so confirming its source is essential.
The Nutritional Benefits of Mozzarella During Pregnancy
Mozzarella isn’t just tasty; it’s packed with nutrients that support both mother and baby. Here’s why it can be a smart addition to your pregnancy diet—if chosen wisely:
- Protein: Essential for fetal growth and tissue repair.
- Calcium: Supports bone development in the baby and maintains maternal bone health.
- Vitamin B12: Crucial for brain development and red blood cell production.
- Phosphorus: Works with calcium to build strong bones and teeth.
Eating mozzarella offers a tasty way to meet increased nutritional needs during pregnancy without adding excessive calories or fats.
Comparing Fresh vs. Aged Mozzarella
Fresh mozzarella is soft, moist, and often packed in brine or whey. It has a delicate flavor and melts beautifully on dishes like pizza or caprese salad. Aged mozzarella varieties (like low-moisture mozzarella) have firmer textures and longer shelf lives due to lower moisture content.
For pregnant women, fresh mozzarella made from pasteurized milk is generally safe but should be consumed quickly after opening due to its short shelf life. Aged mozzarella has less moisture and lower bacterial risk but still must be pasteurized.
Is Mozzarella Safe To Eat When Pregnant? Risks of Unpasteurized Cheese
Unpasteurized cheeses carry a risk of harboring Listeria bacteria because raw milk can contain pathogens if not properly handled. Listeria can survive refrigeration temperatures and multiply over time in soft cheeses.
Pregnant women consuming unpasteurized mozzarella expose themselves to potential infection with serious consequences:
- Miscarriage or stillbirth
- Preterm labor
- Neonatal infection leading to sepsis or meningitis
In many countries, regulations require commercial cheese producers to use pasteurized milk for cheeses sold in supermarkets, but artisan or imported products may not always comply.
The Importance of Reading Labels Carefully
Labels are your best friend when shopping for mozzarella during pregnancy. Look for clear indications such as:
- “Made from pasteurized milk”
- “Pasteurized” certification seals
- Avoid cheeses simply labeled “raw” or “unpasteurized”
If you’re dining out or eating homemade dishes, don’t hesitate to ask about the cheese source.
Safe Ways to Enjoy Mozzarella While Expecting
You don’t have to give up your favorite cheesy treats during pregnancy if you follow these tips:
- Choose Pasteurized Varieties: Always pick mozzarella labeled as pasteurized.
- Avoid Soft Cheeses Without Labeling: Skip fresh cheeses without clear pasteurization info.
- Cook Thoroughly: Heating cheese until steaming hot kills most bacteria; melted pizza toppings are generally safe.
- Avoid Cross-Contamination: Use clean utensils and store cheese properly in sealed containers at cold temperatures.
- Limit Consumption of Homemade Cheese: Homemade mozzarella may not be pasteurized; avoid unless you trust the source completely.
These precautions help reduce risks while allowing you to enjoy delicious meals featuring mozzarella.
Mozzarella in Popular Pregnancy-Friendly Recipes
Mozzarella shines in many dishes that suit pregnancy nutrition goals:
- Baked pasta dishes: Cheese melts beautifully when baked thoroughly.
- Caprese salad: Use fresh pasteurized mozzarella paired with ripe tomatoes and basil.
- Mozzarella-stuffed chicken breasts: Cooking ensures safety while adding flavor.
Cooking is often your ally—heat kills harmful bacteria effectively.

The Science Behind Listeria Risks in Mozzarella Cheese During Pregnancy
Listeria monocytogenes thrives in moist environments like soft cheeses made from raw milk because they provide ideal conditions for bacterial growth at refrigerator temperatures. Fresh mozzarella’s high moisture content means any contamination can multiply quickly if the cheese isn’t properly stored or handled.
The incubation period for listeriosis ranges from a few days up to three weeks after ingestion. Symptoms include fever, muscle aches, nausea—often mild but potentially devastating during pregnancy due to fetal vulnerability.
Research consistently shows that pregnant women who consume unpasteurized dairy products have significantly higher rates of listeriosis than those who avoid them altogether or choose only pasteurized options.
Mozzarella’s Role Compared To Other Dairy Products In Listeria Outbreaks
While soft cheeses like feta and brie often top lists linked with listeriosis outbreaks due to their raw milk origins or poor handling practices, fresh mozzarella has also been implicated occasionally when unpasteurized sources were involved.
Commercial production standards have improved drastically over recent decades reducing risks significantly—but vigilance remains key for pregnant consumers.
