Blue cheese is generally unsafe during pregnancy due to the risk of Listeria infection from unpasteurized milk.
Understanding the Risks of Blue Cheese During Pregnancy
Pregnancy demands extra caution with food choices because certain foods can pose risks to both the mother and the developing baby. Blue cheese, with its distinctive mold veins and creamy texture, is often questioned for its safety during this sensitive period. The main concern revolves around the possibility of Listeria monocytogenes contamination—a bacterium that can cause listeriosis, a serious infection particularly dangerous for pregnant women.
Listeria can cross the placental barrier, potentially leading to miscarriage, stillbirth, premature delivery, or severe neonatal infection. This makes it crucial to scrutinize whether blue cheese is a safe choice during pregnancy. The risk largely depends on how the cheese is made—specifically whether it’s made from pasteurized or unpasteurized milk.
What Makes Blue Cheese Risky?
Blue cheese typically involves adding Penicillium mold cultures that create its signature blue or green veins. While these molds themselves are harmless and even beneficial for flavor and texture development, the real issue lies in the milk source and production process.
Unpasteurized milk cheeses are more prone to harboring harmful bacteria like Listeria. Pasteurization involves heating milk to kill pathogens without affecting flavor too much. Unfortunately, many traditional blue cheeses use raw milk to preserve authentic taste and texture, increasing contamination risks.
Pregnant women’s immune systems are naturally suppressed to tolerate the fetus, making them more vulnerable to infections like listeriosis. Thus, eating blue cheese made from unpasteurized milk is generally discouraged during pregnancy.
Pasteurized vs. Unpasteurized Blue Cheese: What’s Safe?
Not all blue cheeses are created equal when it comes to safety in pregnancy. The critical factor is whether the cheese is made from pasteurized milk.
- Pasteurized Blue Cheese: These cheeses have undergone heat treatment that kills harmful bacteria. Examples include some commercially produced varieties labeled as “pasteurized.” These are generally considered safe for pregnant women.
- Unpasteurized Blue Cheese: Often labeled as “raw milk” cheese or lacking pasteurization information, these carry a higher risk of contamination and should be avoided.
Reading labels carefully is essential because some blue cheeses might not explicitly state their pasteurization status. When in doubt, it’s safest to steer clear or consult with a healthcare provider.
Common Types of Blue Cheese and Their Pasteurization Status
| Blue Cheese Type | Typical Milk Source | Pasteurization Status |
|---|---|---|
| Roquefort | Sheep’s Milk | Usually Unpasteurized (High Risk) |
| Gorgonzola | Cow’s Milk | Both Pasteurized & Unpasteurized Versions Available |
| Danish Blue (Danablu) | Cow’s Milk | Mostly Pasteurized (Lower Risk) |
| Cabrales | Cow’s/Goat’s/Sheep’s Milk Blend | Largely Unpasteurized (High Risk) |
| Bleu d’Auvergne | Cow’s Milk | Often Pasteurized (Lower Risk) |
This table highlights why checking specific product details matters since some blue cheeses have safer versions available.
The Science Behind Listeria and Pregnancy Complications
Listeriosis caused by Listeria monocytogenes is rare but dangerous during pregnancy. This bacterium thrives in refrigerated environments and can contaminate soft cheeses like blue cheese if they’re not properly handled or produced.
Pregnant women face approximately a 10-fold increased risk of listeriosis compared to non-pregnant adults. Symptoms might be mild or flu-like but can escalate quickly to severe complications including:
- Meningitis: Infection of membranes around the brain.
- Bacteremia: Bacteria spreading through the bloodstream.
- Poor fetal outcomes: Miscarriage, stillbirth, premature birth.
The incubation period can vary widely—from a few days up to several weeks—making diagnosis tricky without awareness of recent food exposures.
Nutritional Benefits vs Risks: Should You Avoid Blue Cheese Entirely?
Blue cheese packs nutritional value—it’s rich in calcium, protein, vitamin A, and phosphorus—all vital for maternal health and fetal development. It also contains probiotics that may support gut health.
However, these benefits don’t outweigh potential infection risks during pregnancy unless you’re certain about pasteurization and hygiene standards.
If you crave blue cheese flavors while pregnant:
- Select only pasteurized varieties from reputable brands.
- Avoid soft or semi-soft cheeses unless confirmed pasteurized.
- If unsure about source or label clarity, skip it altogether.
Balancing enjoyment with safety means choosing wisely rather than cutting out all dairy indiscriminately.
Alternatives That Deliver Similar Taste Safely
If you want that tangy bite without risking illness:
- Cream Cheese: Usually pasteurized and safe when fresh.
- Cottage Cheese: Mild flavor with similar creamy texture.
- Pasteurized Feta: Crumbly but less risky option.
These substitutes provide calcium and protein without exposing you to potential pathogens lurking in unpasteurized soft cheeses like traditional blue varieties.
The Role of Food Safety Practices at Home
Even pasteurized blue cheese requires proper handling:
- Avoid cross-contamination: Use clean utensils and surfaces when cutting or serving cheese.
- Store at correct temperatures: Keep refrigerated below 40°F (4°C).
- Check expiration dates: Consume before expiry for best safety.
Improper storage after purchase can increase bacterial growth risk regardless of initial pasteurization status.
Avoiding Homemade or Artisan Varieties During Pregnancy
Homemade or artisan blue cheeses often lack consistent quality control measures compared to industrially produced ones. They may use raw milk and traditional aging methods that increase microbial risks.
Pregnant women should steer clear of these options since verifying safety is nearly impossible outside regulated environments.
Listeriosis Prevention Beyond Blue Cheese Avoidance
Preventing listeriosis involves more than just avoiding risky cheeses:
- Avoid deli meats unless heated thoroughly before eating.
- Avoid refrigerated smoked seafood unless cooked properly.
- Avoid raw sprouts which may harbor bacteria.
Maintaining good kitchen hygiene practices reduces overall infection risk during pregnancy significantly.

Frequently Asked Questions
Is Blue Cheese Safe During Pregnancy?
Blue cheese is generally unsafe during pregnancy if made from unpasteurized milk due to the risk of Listeria infection. Listeria can cause serious complications for both mother and baby, so it’s important to avoid unpasteurized blue cheese while pregnant.
Why is Blue Cheese Risky for Pregnant Women?
The main risk comes from Listeria monocytogenes, a harmful bacterium that can be present in unpasteurized milk cheeses like many blue cheeses. This infection can lead to miscarriage, stillbirth, or severe illness in newborns, making blue cheese risky during pregnancy.
Can Pregnant Women Eat Pasteurized Blue Cheese?
Yes, pasteurized blue cheese is generally considered safe during pregnancy. Pasteurization kills harmful bacteria including Listeria, reducing the risk of infection. Always check labels carefully to confirm the cheese is made from pasteurized milk.
How Can I Tell if Blue Cheese Is Safe During Pregnancy?
Check the packaging for a “pasteurized” label or confirm with the seller. Avoid any blue cheese labeled as “raw milk” or without clear pasteurization information. When in doubt, it’s safer to avoid blue cheese while pregnant.
What Are the Alternatives to Blue Cheese During Pregnancy?
Pregnant women can choose cheeses made from pasteurized milk such as cream cheese, mozzarella, or cheddar. These options carry a lower risk of Listeria and provide safe alternatives to enjoy dairy without compromising health.
The Bottom Line – Is Blue Cheese Safe During Pregnancy?
The short answer: most traditional blue cheeses made from unpasteurized milk carry a significant risk of Listeria contamination and should be avoided by pregnant women entirely. Opting only for clearly labeled pasteurized versions minimizes this risk substantially but still requires caution regarding storage and handling practices.
While tempting due to its unique flavor profile and nutritional benefits, blue cheese poses avoidable dangers during pregnancy that aren’t worth taking lightly given potential severe consequences for mother and child alike.
Choosing safer dairy options rich in calcium and protein ensures both enjoyment and peace of mind throughout this crucial time without compromising health outcomes for you or your baby.
