If you accidentally consumed unpasteurized cheese during pregnancy, it’s important to remain calm but informed. Unpasteurized dairy products carry a risk of harboring harmful bacteria like Listeria, which can cause listeriosis—a rare but serious infection that may lead to complications such as miscarriage, preterm labor, or illness in the newborn. However, the risk of infection is relatively low, and many women consume such foods without issue. Monitor yourself for symptoms like fever, muscle aches, or gastrointestinal issues, and contact your healthcare provider if you experience any concerns. They may recommend testing or provide guidance based on your specific situation. To minimize future risks, always check labels for pasteurization and avoid soft cheeses like Brie, Camembert, or blue cheese unless they’re clearly labeled as pasteurized.

Potential Risks: Listeriosis dangers, miscarriage, stillbirth, or newborn infection risks from unpasteurized cheese consumption during pregnancy
Accidentally consuming unpasteurized cheese during pregnancy can expose both mother and fetus to Listeria monocytogenes, a bacterium that thrives in raw dairy products. Listeriosis, the infection caused by this bacterium, is rare but poses severe risks. Pregnant women are 10 times more likely to contract listeriosis due to hormonal changes that weaken their immune systems. The bacterium can cross the placenta, potentially leading to miscarriage, stillbirth, or severe infections in the newborn. While pasteurization kills Listeria, unpasteurized cheeses like Brie, Camembert, blue-veined cheeses, and Mexican-style cheeses like queso fresco remain breeding grounds for this pathogen.
The risks of listeriosis extend beyond the mother. If the infection reaches the fetus, it can cause premature delivery, low birth weight, or life-threatening neonatal sepsis. Newborns infected with Listeria may exhibit symptoms such as fever, difficulty breathing, or poor feeding within the first few days of life. In severe cases, untreated neonatal listeriosis can be fatal. The CDC estimates that approximately 1,600 people contract listeriosis annually in the U.S., with pregnant women and their newborns accounting for nearly one-fifth of these cases.
While the risk of listeriosis from a single exposure to unpasteurized cheese is low, the consequences can be devastating. For instance, a 2017 outbreak linked to soft raw milk cheese resulted in 2 deaths and 1 miscarriage. Pregnant women should avoid unpasteurized dairy products entirely, as the potential harm far outweighs the fleeting pleasure of indulging in a risky food. Always check labels for "pasteurized" and avoid soft cheeses unless explicitly confirmed safe.
Practical precautions can minimize risk. Hard cheeses like cheddar or Swiss are generally safe, as are pasteurized versions of soft cheeses. When dining out, ask about cheese sources and preparation methods. If accidental consumption occurs, monitor for symptoms such as fever, muscle aches, or gastrointestinal distress, which typically appear 1-4 weeks post-exposure. While most cases resolve without treatment, pregnant women should seek immediate medical attention if symptoms arise, as prompt antibiotic therapy can prevent fetal complications.
In summary, unpasteurized cheese consumption during pregnancy is a preventable yet significant risk factor for listeriosis. The potential for miscarriage, stillbirth, or newborn infection underscores the importance of vigilance. By adhering to food safety guidelines and recognizing early warning signs, expectant mothers can protect themselves and their babies from this dangerous bacterium. When in doubt, err on the side of caution—a momentary indulgence is never worth jeopardizing a healthy pregnancy.

Symptoms to Watch: Fever, muscle pain, nausea, or diarrhea after eating unpasteurized cheese while pregnant
Accidentally consuming unpasteurized cheese during pregnancy can expose you to harmful bacteria like Listeria monocytogenes, which may lead to listeriosis. This infection poses risks to both you and the fetus, making it crucial to recognize early symptoms. Fever, muscle pain, nausea, and diarrhea are key indicators that warrant immediate attention. These symptoms typically appear within a few days to several weeks after exposure, though they can sometimes take longer to manifest. Monitoring your health closely after such an incident is essential for timely intervention.
Fever is often the first red flag, signaling your body’s attempt to fight infection. A temperature above 100.4°F (38°C) should prompt a call to your healthcare provider. Muscle pain, particularly in the back and joints, may accompany the fever, mimicking flu-like symptoms. However, unlike the flu, listeriosis-related muscle pain tends to be more localized and persistent. If you experience these symptoms alongside gastrointestinal issues like nausea or diarrhea, it’s critical to act swiftly, as dehydration can exacerbate the condition, especially during pregnancy.
Nausea and diarrhea are particularly concerning because they can lead to fluid loss, which is dangerous for both you and the developing baby. Pregnant individuals are already at higher risk of dehydration due to increased fluid demands. If vomiting or diarrhea persists for more than 24 hours, seek medical attention. Oral rehydration solutions can help maintain electrolyte balance, but they should not replace professional care. Always consult your doctor before taking any medications, even over-the-counter ones, during pregnancy.
While these symptoms are alarming, not everyone who consumes unpasteurized cheese will develop listeriosis. However, pregnant individuals are ten times more likely to contract the infection due to hormonal changes that weaken the immune system. If you suspect exposure, document the type and amount of cheese consumed, as well as the timing of symptoms. This information will aid your healthcare provider in assessing risk and determining whether testing or treatment is necessary. Early detection and treatment with antibiotics can prevent severe complications, such as miscarriage, preterm labor, or neonatal infection.
Practical prevention is equally important. Always check labels for "pasteurized" when purchasing cheese, and avoid soft cheeses like Brie, Camembert, blue-veined cheeses, and Mexican-style cheeses (e.g., queso fresco) unless explicitly labeled as pasteurized. Hard cheeses, shredded cheeses, and cream cheese are generally safe. When dining out, don’t hesitate to ask about pasteurization. While one accidental exposure doesn’t guarantee illness, staying vigilant and informed minimizes risks, ensuring a healthier pregnancy for you and your baby.

Prevention Tips: Check labels, choose pasteurized cheese, and avoid soft cheeses like Brie or Camembert
Pregnant women are often advised to avoid certain foods to minimize health risks, and unpasteurized cheese is a common concern. The risk lies in the potential presence of harmful bacteria like Listeria monocytogenes, which can cause listeriosis—a serious infection that may lead to miscarriage, premature delivery, or severe illness in newborns. If you’ve accidentally consumed unpasteurized cheese, it’s crucial to monitor for symptoms like fever, muscle pain, or gastrointestinal issues, and consult a healthcare provider immediately. However, prevention is always better than cure, and understanding how to avoid this risk is key.
Step 1: Scrutinize Labels for Pasteurization Status
The first line of defense is reading labels carefully. Look for terms like "pasteurized," "made with pasteurized milk," or "pasteurized process cheese." If the label is unclear or absent, assume the cheese is unpasteurized, especially if it’s imported or from a local farm. For example, hard cheeses like cheddar or Swiss are typically pasteurized, but artisanal varieties may not be. When in doubt, contact the manufacturer or skip the product entirely. This simple habit can significantly reduce your exposure to potential risks.
Step 2: Prioritize Pasteurized Cheese Varieties
Opting for pasteurized cheese is a straightforward way to eliminate the risk of bacterial contamination. Pasteurization involves heating milk to a specific temperature to kill harmful pathogens, making it safe for consumption. Popular pasteurized options include mozzarella, provolone, and processed cheese slices. For those who enjoy softer textures, pasteurized cream cheese, cottage cheese, or string cheese are excellent alternatives. By making pasteurized cheese your go-to choice, you can enjoy your favorite flavors without worry.
Step 3: Steer Clear of High-Risk Soft Cheeses
Soft cheeses like Brie, Camembert, blue cheese, and queso fresco are more likely to harbor Listeria due to their moisture content and production methods. Even if these cheeses are made with pasteurized milk, their manufacturing processes can reintroduce bacteria. For instance, the mold in blue cheese is cultivated in environments that may not be sterile. While these cheeses are safe for non-pregnant individuals, pregnant women should avoid them entirely. Instead, consider substituting with pasteurized versions or harder cheeses that pose less risk.
Caution: Cross-Contamination and Storage Practices
Beyond selecting the right cheese, proper handling is essential. Always store cheese at or below 40°F (4°C) to slow bacterial growth. Avoid leaving cheese unrefrigerated for more than two hours, or one hour if the temperature is above 90°F (32°C). Additionally, use separate cutting boards and utensils for raw and ready-to-eat foods to prevent cross-contamination. These precautions ensure that even pasteurized cheese remains safe to consume.
Accidentally consuming unpasteurized cheese during pregnancy can be alarming, but proactive measures can prevent such incidents. By checking labels, choosing pasteurized options, and avoiding high-risk soft cheeses, you take control of your dietary safety. Pairing these steps with proper food handling practices creates a robust defense against potential risks. Remember, small changes in your shopping and eating habits can make a significant difference in protecting both you and your baby.
