Parmesan cheese is safe to eat during pregnancy if it is made from pasteurized milk, offering rich nutrients without harmful bacteria.
Understanding Parmesan Cheese and Pregnancy Safety
Parmesan cheese, known for its sharp, nutty flavor and granular texture, is a staple in many kitchens worldwide. It’s a hard Italian cheese traditionally made from cow’s milk and aged for months or even years. But when you’re expecting, every bite matters—especially when it comes to dairy products. The question “Is Parmesan Safe During Pregnancy?” pops up frequently because pregnant women must avoid foods that might harbor harmful bacteria like Listeria monocytogenes.
Listeria infection during pregnancy can lead to severe complications such as miscarriage, preterm labor, or even stillbirth. So, knowing which cheeses are safe is crucial to protect both mother and baby. Fortunately, Parmesan cheese generally falls on the safe side of the spectrum—but there are nuances you should understand before sprinkling it liberally on your pasta.
Pasteurized vs. Unpasteurized Parmesan: What You Need to Know
The key factor that determines whether Parmesan is safe during pregnancy lies in its production process—specifically pasteurization. Pasteurization involves heating milk to a certain temperature to kill harmful bacteria without significantly affecting taste or nutritional value.
Most commercially available Parmesan cheeses in supermarkets are made from pasteurized milk. This means they’ve gone through this heat treatment, making them safe for pregnant women to consume. On the other hand, some artisanal or imported Parmesans might be crafted using raw (unpasteurized) milk. These products carry a higher risk of contamination with Listeria and should be avoided during pregnancy.
How Aging Affects Safety
Parmesan is an aged cheese, typically matured for 12 months or longer. Aging changes its texture and flavor but also reduces moisture content drastically. Low moisture environments make it harder for harmful bacteria to survive.
Still, aging alone doesn’t guarantee safety if the milk wasn’t pasteurized initially. So while long-aged cheeses like Parmesan are less risky than soft cheeses (e.g., Brie or Camembert), confirming pasteurization status remains essential.
Nutritional Benefits of Parmesan Cheese During Pregnancy
Aside from safety concerns, Parmesan offers excellent nutritional value that supports pregnancy health:
- High Protein Content: Protein helps build your baby’s tissues and organs.
- Rich in Calcium: Essential for strong bones and teeth development.
- Phosphorus: Works with calcium for bone health and energy metabolism.
- Vitamin A: Important for vision and immune function.
- Zinc: Supports cell growth and repair.
Because Parmesan is dense and flavorful, a small amount goes a long way nutritionally without adding excessive calories or fat.

The Risk of Listeria in Dairy Products During Pregnancy
Listeriosis is an infection caused by Listeria monocytogenes bacteria found in contaminated food such as unpasteurized dairy products, deli meats, and some soft cheeses. Pregnant women are about ten times more likely than others to get listeriosis because pregnancy weakens the immune system slightly.
Listeria can cross the placental barrier affecting fetal development severely. Symptoms may be mild or flu-like but can escalate quickly in pregnant women.
Listeria Risk: Hard vs Soft Cheeses
Soft cheeses like Brie, Camembert, feta, blue cheese, and queso fresco have higher moisture content which provides an ideal environment for Listeria growth if unpasteurized milk is used.
Hard cheeses like Parmesan have lower moisture levels due to extensive aging processes which limit bacterial growth potential significantly—even if made from unpasteurized milk.
However:
- If the hard cheese is unpasteurized but aged less than 60 days (the FDA guideline), it poses higher risk.
- If it’s pasteurized and properly aged (like most commercial Parmesans), it’s considered very low risk.
This explains why many health authorities advise pregnant women to avoid soft cheeses unless labeled pasteurized but allow hard cheeses like Parmesan with confidence.
Selecting Safe Parmesan Cheese While Pregnant: Tips & Tricks
To enjoy Parmesan safely during pregnancy without worry:
- Check Labels Carefully: Look for “pasteurized” on packaging before purchasing.
- Avoid Artisan Imports Without Clear Pasteurization Info: They may use raw milk increasing risk.
- Aged Longer Than 12 Months: Longer aging reduces moisture further lowering bacterial survival chances.
- Avoid Bulk Grated Cheese From Unknown Sources: Cross-contamination risk is higher here.
If dining out or ordering takeout with parmesan toppings—ask how the cheese was sourced or opt out if unsure.
The Role of Proper Storage & Handling at Home
Even safe parmesan can become risky if mishandled:
- Keeps It Refrigerated: Store at temperatures below 40°F (4°C).
- Avoid Cross-Contamination: Use clean utensils each time you handle cheese.
- Avoid Leaving Out Too Long: Don’t leave parmesan sitting out at room temperature over two hours.
Following these simple steps ensures your parmesan remains fresh and safe throughout your pregnancy journey.
Culinary Uses of Parmesan During Pregnancy: Flavor Meets Safety
Parmesan’s versatility makes it easy to incorporate safely into meals without sacrificing taste:
- Pasta Dishes: Sprinkle over cooked pasta dishes after cooking rather than raw consumption from unknown sources.
- Baked Recipes:Add parmesan into casseroles or gratins where heat kills any residual bacteria if present.
- Creamy Sauces:Melt parmesan into cream-based sauces that cook thoroughly before serving.
Avoid eating large chunks of parmesan alone unless you’re confident about its source and quality control.
