Pregnant women should avoid soft, unpasteurized cheeses to reduce the risk of listeria infection and protect fetal health.
Understanding the Risks Behind Cheese Consumption During Pregnancy
Pregnancy demands a heightened awareness of diet because certain foods can pose risks to both mother and baby. Cheese, a beloved dairy product, can sometimes harbor harmful bacteria or toxins. The primary concern revolves around listeria monocytogenes, a bacterium that causes listeriosis—a rare but serious infection that can lead to miscarriage, preterm labor, or severe neonatal illness.
Listeria thrives in soft cheeses made from unpasteurized milk. Unlike hard cheeses, which generally have lower moisture content and acidity levels that inhibit bacterial growth, soft cheeses provide an ideal environment for bacteria to flourish. Pregnant women’s immune systems are naturally suppressed to accommodate the fetus, making them more susceptible to infections like listeriosis.
Besides listeria, certain cheeses may contain high levels of salt or fat, which aren’t ideal for pregnancy health but are less critical than bacterial contamination risks. Understanding which cheeses are risky can help expectant mothers navigate their cravings safely without compromising their baby’s well-being.
What Cheese To Not Eat When Pregnant? Key Varieties to Avoid
Not all cheese is off-limits during pregnancy. However, some specific types should be avoided due to their production methods and texture. Here’s a detailed breakdown:
Soft Cheeses Made from Unpasteurized Milk
Soft cheeses with unpasteurized milk are the biggest red flags. These include:
- Brie: Known for its creamy texture and edible rind, Brie is often made from raw milk.
- Camembert: Similar to Brie but typically smaller; also frequently unpasteurized.
- Feta: A crumbly cheese traditionally made from sheep or goat’s milk, often unpasteurized.
- Queso Fresco: A fresh Mexican cheese usually unpasteurized and prone to contamination.
- Blue-veined Cheeses (Roquefort, Gorgonzola): These have mold cultures and are often soft; some versions use raw milk.
Listeria can survive in these cheeses because pasteurization—a heat treatment that kills harmful bacteria—hasn’t been applied. Even if pasteurized versions exist, many traditional recipes still rely on raw milk.
Semi-soft Cheeses with Potential Risks
Cheeses like mozzarella or ricotta generally pose less risk if pasteurized but may still cause concern if homemade or sourced from unregulated dairies. Always check labels carefully.
Hard Cheeses Generally Considered Safe
Hard cheeses such as cheddar, Parmesan, Swiss, and gouda have low moisture content and are usually safe when made with pasteurized milk. The drying process makes it difficult for bacteria like listeria to survive.
The Role of Pasteurization: Why It Matters So Much
Pasteurization involves heating milk to a specific temperature for a set time to kill pathogens without significantly altering taste or nutritional value. This process dramatically reduces the risk of foodborne illnesses.
Pregnant women should always opt for cheeses labeled as “pasteurized.” Even though some artisanal or imported cheeses may not carry this label clearly, it’s safer to avoid any doubt.
The Centers for Disease Control and Prevention (CDC) strongly advises pregnant women against consuming unpasteurized dairy products due to documented outbreaks of listeriosis linked directly to these foods.
The Confusion Around “Raw Milk” Cheeses
Raw milk cheese is popular among food enthusiasts for its complex flavors and traditional preparation methods. However, during pregnancy, these benefits don’t outweigh the risks.
Many countries regulate raw milk cheese sales differently. In the U.S., raw milk cheeses must be aged at least 60 days before sale; however, soft raw milk cheeses often don’t meet this criterion and pose higher risks.
If you’re unsure whether a cheese is pasteurized or not at a restaurant or market stall, it’s best to avoid it altogether during pregnancy.
Nutritional Benefits of Safe Cheese Choices During Pregnancy
While avoiding risky cheeses is crucial, dairy remains an important source of calcium, protein, vitamin D, and other nutrients essential for fetal development.
Safe options include:
- Cottage Cheese: Pasteurized cottage cheese offers protein without excess fat.
- Pasteurized Hard Cheeses: Cheddar and Swiss provide calcium critical for bone growth.
- Pasteurized Mozzarella: Offers versatility in meals without safety concerns.
Including these in a balanced diet supports maternal bone health and fetal skeletal development while satisfying taste buds safely.
The Danger of Listeriosis: Why Cheese Matters
Listeriosis is rare but disproportionately dangerous during pregnancy. Symptoms include fever, muscle aches, nausea, vomiting—often mistaken for flu-like illness—and can progress rapidly.
The infection can cross the placental barrier causing miscarriage or stillbirth if untreated promptly. Newborns infected with listeria face severe complications including meningitis or sepsis.
Cheese-related outbreaks have been documented worldwide—especially linked with soft cheeses like Brie or Queso Fresco—making avoidance critical during pregnancy.
Listeria Survival in Refrigeration
Unlike many bacteria that perish under cold storage conditions, listeria can grow even at refrigerator temperatures. This means contaminated cheese stored properly may still cause infection if eaten by pregnant women.
Therefore, relying on proper refrigeration alone isn’t enough protection; choosing safe cheese types is non-negotiable.
A Handy Table: Safe vs Unsafe Cheeses During Pregnancy
| Cheese Type | Status During Pregnancy | Reason / Notes |
|---|---|---|
| Brie (Unpasteurized) | Avoid | Soft texture & raw milk increase listeria risk |
| Pasteurized Cheddar | Safe | Hard cheese & pasteurization reduce hazards |
| Queso Fresco (Unpasteurized) | Avoid | Common source of listeriosis outbreaks in pregnancy |
| Pasteurized Mozzarella (Low-moisture) | Safe | Pasta dishes & salads safe if pasteurized version used |
| Blue-veined Raw Milk Cheese (Roquefort) | Avoid | Mold & raw milk increase contamination risk |
| Cottage Cheese (Pasteurized) | Safe | Nutrient-rich & low-risk when pasteurized |
Tips For Safely Enjoying Cheese During Pregnancy
Cravings don’t disappear just because you’re pregnant! Here are practical tips to enjoy cheese safely:
- Always check labels: Look specifically for “pasteurized” on packaging.
- Avoid deli counter samples: Cross-contamination risks are high here.
- If dining out: Ask restaurant staff about cheese preparation methods.
- Avoid homemade soft cheeses unless confirmed safe: Artisan products may not follow strict hygiene standards.
Remember that cooking cheese thoroughly kills most pathogens—melting Brie into a baked dish is safer than eating it cold straight off the rind.
The Role of Refrigeration and Storage Hygiene at Home
Proper storage minimizes bacterial growth but doesn’t eliminate all risks with unsafe cheese types:
- Keeps cheese sealed tightly away from other foods.
- Keeps fridge temperature below 40°F (4°C).
Discard any cheese past its expiration date or showing mold growth outside expected blue mold varieties.

Can I Eat Pasteurized Mozzarella or Ricotta While Pregnant?
Pasteurized mozzarella and ricotta are generally safe for pregnant women. However, homemade or unregulated versions might not be pasteurized and could pose a risk, so always check the source before consumption.
What Are the Risks of Eating Unpasteurized Cheese When Pregnant?
Unpasteurized cheese can contain listeria monocytogenes, which causes listeriosis. This infection may lead to miscarriage, preterm labor, or severe illness in newborns, making it crucial to avoid these cheeses during pregnancy.
The Final Word – What Cheese To Not Eat When Pregnant?
Avoiding soft cheeses made from unpasteurized milk is non-negotiable during pregnancy due to the serious threat posed by listeriosis. Stick firmly to pasteurized hard cheeses like cheddar or Swiss along with pasteurized fresh options such as cottage cheese or mozzarella. Reading labels carefully and asking questions when dining out ensures you stay on the safe side without missing out on delicious dairy nutrition.
Pregnancy calls for smart choices—not sacrifices—and knowing exactly what cheese to avoid empowers you to protect your baby while enjoying your meals confidently.
