Soft, unpasteurized cheeses pose risks during pregnancy due to potential listeria contamination.
The Risks Behind Certain Cheeses During Pregnancy
Pregnancy demands a sharp eye on diet, especially when it comes to dairy products like cheese. The main concern isn’t just calories or fat content—it’s about food safety. Some cheeses can harbor harmful bacteria, particularly Listeria monocytogenes, which can cause listeriosis, a serious infection that poses risks to both mother and baby.
Listeria is sneaky. Unlike many bacteria, it can grow even in refrigerated environments. This makes some soft cheeses particularly risky if they’re made from unpasteurized milk. Pregnant women are about 10 times more likely to get listeriosis than the general population, and the consequences can be severe: miscarriage, stillbirth, premature delivery, or severe illness in newborns.
So, knowing what cheese you can’t eat when pregnant isn’t just about avoiding tummy troubles; it’s about protecting your baby’s health.
Why Soft Cheeses Are Usually Off-Limits
Soft cheeses have higher moisture content and softer textures that make them prime breeding grounds for bacteria like Listeria. This includes varieties such as Brie, Camembert, Roquefort, and feta when made from raw milk.
The problem intensifies if the cheese is unpasteurized—meaning it hasn’t been heat-treated to kill harmful bacteria. Pasteurization is a safety step that eliminates pathogens without significantly affecting flavor or texture.
Soft cheeses made with pasteurized milk are generally safe because the heat treatment kills Listeria. However, if the label doesn’t specify “pasteurized,” it’s safer to avoid them during pregnancy.
Hard cheeses like cheddar or Swiss have low moisture content and dense textures that make bacterial growth unlikely. They are usually safe whether pasteurized or not.
Common Soft Cheeses to Avoid If Unpasteurized
- Brie
- Camembert
- Feta
- Blue-veined cheeses (Roquefort, Gorgonzola)
- Queso fresco
- Mozzarella (if unpasteurized)
It’s crucial to check packaging labels carefully or ask your cheesemonger whether the cheese is pasteurized.
Understanding Pasteurization and Its Importance
Pasteurization involves heating milk to a specific temperature for a set duration to kill pathogens without ruining taste or nutrients. Most commercially available cheeses in many countries are made from pasteurized milk due to strict food safety regulations.
However, artisanal or imported cheeses might be made from raw milk. These carry a higher risk of contamination unless they undergo aging processes that reduce pathogens over time (usually 60 days or more). Yet, even aged raw milk cheeses aren’t always considered safe during pregnancy.
If you’re ever unsure about a cheese’s pasteurization status, it’s best to err on the side of caution and avoid it until after pregnancy.
The Role of Aging in Cheese Safety
Aging soft raw milk cheeses for at least 60 days reduces bacterial risk because acidity increases and moisture decreases over time—conditions unfavorable for Listeria survival. Hard raw milk cheeses aged longer than this period are generally safer too.
Still, pregnant women are advised against consuming raw milk cheeses regardless of aging because no method guarantees complete safety against Listeria during pregnancy.
Safe Cheese Options for Pregnant Women
Not all cheese needs to be off-limits! Many delicious options are perfectly safe when pregnant:
- Hard Cheeses: Cheddar, Parmesan, Swiss, Gouda.
- Semi-Hard Cheeses: Edam, Colby.
- Pasteurized Soft Cheeses: Cottage cheese, cream cheese, processed cheese slices.
- Pasteurized Mozzarella: Commonly used in many dishes.
These choices provide essential calcium and protein without risking exposure to harmful bacteria.
Nutritional Benefits of Safe Cheeses During Pregnancy
Cheese supplies vital nutrients such as calcium for bone development, protein for tissue growth, vitamin B12 for neurological function, and phosphorus for cell repair. Including safe dairy in moderation supports both maternal health and fetal development.
A Handy Table: Cheese Types and Pregnancy Safety
| Cheese Type | Pasteurization Status | Pregnancy Safety |
|---|---|---|
| Brie/Camembert | Often unpasteurized (check label) | Avoid unless clearly pasteurized |
| Cheddar/Parmesan/Swiss | Usually pasteurized or aged hard cheese | Safe to eat during pregnancy |
| Feta (raw milk) | Often unpasteurized traditional varieties | Avoid unless pasteurized version available |
| Cottage/Cream Cheese | Pasteruized commercially available types only | Safe when pasteurized; avoid homemade raw versions |
| Mozzarella (fresh) | If pasteurized – safe; if raw – avoid | Select pasteurized brands only during pregnancy |
| Blue Cheese (Roquefort/Gorgonzola) | Seldom pasteurized; high risk of Listeria with raw milk versions | Avoid unless confirmed pasteurized and cooked thoroughly |
The Danger of Homemade or Imported Cheeses Without Labels
Homemade cheeses often lack proper pasteurization controls. Similarly, imported artisanal cheeses may not meet local safety standards or carry clear labels indicating their status. These unknowns increase risks significantly.
Pregnant women should steer clear of any unlabeled soft cheese products from farmers’ markets or foreign imports unless they can confirm they’re made with pasteurized milk under hygienic conditions.
If craving something special from abroad or homemade delights, cooking these cheeses thoroughly until steaming hot can reduce risk but does not guarantee complete safety.
The Importance of Cooking Cheese Thoroughly When Unsure
Heating kills Listeria effectively. Melting soft cheeses on pizza or baking them in casseroles until piping hot transforms risky products into safer options temporarily. However, repeated cooling and reheating should be avoided as bacteria can multiply again if temperature control lapses.
Still, relying on cooking alone isn’t foolproof; prevention by choosing safe varieties is always better than treating potential contamination later.

Frequently Asked Questions
What cheese can’t you eat when pregnant due to listeria risk?
Pregnant women should avoid soft, unpasteurized cheeses like Brie, Camembert, Feta, and Roquefort because they can harbor Listeria bacteria. This infection can cause serious complications including miscarriage and stillbirth.
Why is unpasteurized cheese unsafe to eat when pregnant?
Unpasteurized cheeses haven’t been heat-treated to kill harmful bacteria such as Listeria monocytogenes. Since Listeria can grow even in refrigerated conditions, consuming these cheeses during pregnancy increases the risk of infection.
Are all soft cheeses unsafe to eat when pregnant?
Not all soft cheeses are unsafe. Soft cheeses made from pasteurized milk are generally safe because pasteurization kills harmful bacteria. The key is to check if the cheese label specifies “pasteurized” before consuming.
Can I eat hard cheese when pregnant or is it risky like soft cheese?
Hard cheeses like cheddar and Swiss have low moisture and dense textures that inhibit bacterial growth. They are usually safe to eat during pregnancy regardless of pasteurization status.
How can I tell if a cheese is safe to eat when pregnant?
Always check the packaging for a “pasteurized” label or ask your cheesemonger. Avoid cheeses made from raw milk or those without clear pasteurization information to reduce the risk of listeriosis during pregnancy.
Listeriosis Symptoms and Why Prompt Action Matters During Pregnancy
Listeriosis symptoms often mimic mild flu: fever, muscle aches, nausea. Some develop diarrhea or headaches too. Because these signs overlap with common illnesses during pregnancy, infections may go unnoticed until complications arise.
If you suspect consuming risky cheese or experience unusual symptoms after eating dairy products:
- Contact your healthcare provider immediately.
- Mention possible exposure to unpasteurized dairy.Avoiding Cross-Contamination in Your Kitchen Matters Too!
Even safe cheeses can become contaminated if handled improperly:
- Use clean utensils when serving cheese.
- Avoid placing ready-to-eat cheese next to raw meats.
- Store dairy products at proper refrigeration temperatures below 40°F (4°C).
- Discard any soft cheese left out at room temperature over two hours.
- Wash hands thoroughly before handling any food items.
Good hygiene practices minimize exposure risk beyond just choosing the right type of cheese.
The Bottom Line – What Cheese Can’t You Eat When Pregnant?
Soft cheeses made from unpasteurized milk—like Brie, Camembert, feta (raw), blue-veined varieties—are best avoided during pregnancy due to listeria risk. Hard aged cheeses and all pasteurized types offer safer alternatives packed with essential nutrients needed for your growing baby.
Choosing wisely means reading labels carefully and opting for familiar brands that guarantee pasteurization. Cooking questionable soft cheeses thoroughly reduces danger but doesn’t replace selecting safe options outright.
Your baby’s health depends on vigilance around foods prone to contamination—and understanding exactly what cheese can’t you eat when pregnant? now equips you with the knowledge needed to enjoy dairy safely throughout this special time.
