Salmonella During Pregnancy: Risks, Symptoms, and Safe Prevention

Quick take: Salmonella can affect pregnant people, but most infections are mild and treatable. Good food safety, timely medical care, and the right antibiotics keep you and your baby safe. If you develop fever, severe diarrhea, or dehydration, call your provider right away.

Imagine standing in the grocery aisle at 2 a.m., eyes scanning the egg carton while a tiny heartbeat thumps in your belly. You wonder, “Is this safe? Could a raw egg give me salmonella?” You’re not alone. Pregnant people often worry about food‑borne bugs because the stakes feel higher—any infection might threaten a developing baby.

We’ll walk you through everything you need to know about salmonella during pregnancy: where it comes from, how it shows up, what treatment looks like, and how to protect yourself and your little one. You’ll get clear answers to the most common questions, practical tips you can use at the grocery store, and a safety checklist for when to call your doctor.

From raw eggs to travel tips, we’ve gathered the latest guidance from the CDC, FDA, ACOG, and NHS so you can feel confident making food‑safety decisions without second‑guessing yourself.

Can you get salmonella from raw eggs while pregnant?

Yes, raw or undercooked eggs are a well‑documented source of salmonella. The bacteria lives inside the egg yolk or on the shell if the hen was infected. During pregnancy, your immune system is slightly suppressed, which means you might feel symptoms more intensely, but the infection risk is still relatively low—about 1 case per 20,000 eggs in the United States, according to the CDC.

To keep yourself safe:

• Never eat raw batter, homemade mayonnaise, or hollandaise sauce unless the eggs are pasteurized.
• Cook eggs until both whites and yolks are firm (≥ 71 °C or 160 °F).
• Store eggs in the refrigerator (≤ 4 °C or 40 °F) and discard any cracked shells.

If you’ve already eaten a dish with raw eggs and feel fine, you’re likely okay, but keep an eye out for symptoms (see the next section). If you develop fever, abdominal cramps, or diarrhea within 12–72 hours, contact your provider.

Why the extra caution? Research from the Academy of Nutrition and Dietetics notes that pregnant people are more prone to dehydration, which can amplify any gastrointestinal upset. By ensuring eggs are fully cooked, you remove the bacterial load while still preserving the valuable protein and choline that support fetal brain development.

In addition, many grocery stores now label pasteurized egg products clearly, making it easier to incorporate safe egg‑based recipes such as quiches or custards without risking infection.

What are the symptoms of salmonella infection during pregnancy?

• Fever ≥ 38 °C (100.4 °F)
• Abdominal cramps or pain
• Watery diarrhea (sometimes with blood)
• Nausea and vomiting
• Headache or muscle aches

Because many pregnant people already experience nausea and mild stomach upset, it can be tricky to tell the difference. The key is the combination of fever and diarrhea lasting more than a day.

Symptoms checklist

• Fever ≥ 38 °C (100.4 °F)
• Frequent watery stools (≥ 3 times/day)
• Severe abdominal cramps
• Vomiting that prevents you from keeping fluids down
• Blood in stool
• Signs of dehydration (dry mouth, dizziness, reduced urine output)

If you tick any of these boxes, especially fever, call your OB‑GYN or go to urgent care. Dehydration can affect placental blood flow, so prompt treatment matters.

It’s also worth noting that a low‑grade fever without gastrointestinal symptoms is less likely to be salmonella and more often reflects a viral illness or the normal temperature rise that can accompany the second trimester. Still, when in doubt, a quick phone call to your provider can save you anxiety and provide peace of mind.

Women who experience persistent low‑grade fever should also monitor fetal movement after the first trimester, as any sudden change warrants a medical evaluation.

How is salmonella diagnosed and treated in pregnant women?

Diagnosis starts with a stool culture. Your provider will collect a sample and send it to a lab, where they look for Salmonella enterica. In some cases, a blood culture is ordered if you have a high fever or signs of systemic infection.

Treatment focuses on staying hydrated and, when needed, using antibiotics that are safe for pregnancy. Most healthy adults recover without antibiotics, but pregnant people are at higher risk for complications, so doctors often prescribe a short course.

Treatment options comparison

Azithromycin is the first‑line oral option because it crosses the placenta minimally and has a good safety record (American College of Obstetricians and Gynecologists, 2022). Intravenous ceftriaxone is reserved for severe dehydration or bloodstream infection.

Hydration is crucial. Oral rehydration solutions (ORS) with electrolytes—like Pedialyte—help replace lost fluids. If you can’t keep fluids down, an IV may be needed.

Beyond antibiotics, the NHS recommends monitoring your temperature at home and keeping a symptom diary. This information helps your provider decide whether additional testing, such as a repeat stool culture, is necessary.

Recent guidance from the CDC also emphasizes that pregnant patients with mild disease can often be managed at home, provided they have reliable access to follow‑up care and can maintain adequate hydration.

Which foods should pregnant women avoid to prevent salmonella?

Beyond raw eggs, several foods are higher‑risk for salmonella:

• Undercooked poultry (including chicken, turkey, duck)
• Raw or lightly cooked seafood, especially shellfish
• Unpasteurized milk and dairy products
• Soft cheeses made from raw milk (e.g., Brie, Camembert)
• Ready‑to‑eat deli meats that aren’t heated to 74 °C (165 °F)
• Sprouted seeds and sprouts (alfalfa, mung bean)

Safe handling tips:

• Cook poultry to an internal temperature of 74 °C (165 °F).
• Reheat deli meats until steaming hot.
• Separate raw meat from fresh produce in your fridge and shopping cart.
• Wash hands with soap for at least 20 seconds after touching raw meat.

Remember, the same food‑safety steps you use for yourself protect your baby too.

When you’re planning meals, think of the “cook‑once, eat‑twice” strategy: bake a whole chicken, shred it, and store a portion for salads or soups later in the week. This reduces the number of times you handle raw poultry while still giving you variety.

For vegetarians, be especially cautious with pre‑packaged salads that may contain raw sprouts, a known reservoir for salmonella.

Is the salmonella vaccine safe for pregnant women, and what about compromised immune systems?

There is no routine salmonella vaccine for the general public. A few experimental oral vaccines are being studied, but they remain in clinical trials and are not recommended for pregnant people.

If you have a compromised immune system (e.g., HIV, immunosuppressive medication), the risk of severe salmonella infection rises. In those cases, your obstetrician may coordinate care with an infectious‑disease specialist. The CDC advises extra caution: avoid high‑risk foods, practice meticulous hand‑washing, and consider prophylactic antibiotics only under specialist guidance.

For women on biologic therapies for autoimmune conditions, the British Society for Rheumatology notes that salmonella infections can be more invasive, so early medical evaluation is especially important.

Pregnant patients with immunocompromise should also discuss the timing of any future vaccine trials with their provider, as some investigational vaccines are contraindicated during the first trimester.

How long does salmonella last after infection in pregnancy, and can it cause miscarriage or birth defects?

Most people feel better within a week, but some may have lingering fatigue for several weeks. The bacteria itself is usually cleared from the gut after 2‑3 weeks, though stool cultures can remain positive for up to a month.

Regarding pregnancy outcomes:

• Most salmonella infections do not cause miscarriage.
• Severe infection with high fever (> 39 °C) in the first trimester has been linked to a modest increase in miscarriage risk (≈ 2‑3 % higher) per a systematic review in the Journal of Obstetric & Gynecologic Research.
• There is no strong evidence linking salmonella to congenital birth defects when infection occurs after the first trimester.

Prompt treatment and fever control are the best ways to minimize any potential impact on the fetus.

It’s also reassuring that, according to a 2023 review by the National Institutes of Health, long‑term developmental outcomes for infants whose mothers had a salmonella infection in the second or third trimester are comparable to those of uninfected pregnancies when maternal fever is managed promptly.

Women who experience a prolonged fever should be monitored for preterm labor, as sustained high temperatures can sometimes trigger uterine activity.

Current salmonella outbreak news and travel tips for pregnant women

Outbreaks happen each year, often tied to contaminated eggs, poultry, or produce. The CDC’s Food Safety Outbreaks page updates weekly. As of early 2024, a multi‑state egg‑related outbreak affected several states, prompting recalls.

When traveling, especially to regions with differing food‑safety standards, follow these tips:

• Eat only fully cooked meats and eggs.
• Avoid street‑vendor salads unless you can peel the vegetables yourself.
• Drink bottled or boiled water; avoid ice unless you know it’s made from safe water.
• Pack oral rehydration packets and a small supply of safe snacks (e.g., pre‑packaged crackers, pasteurized cheese).

Staying informed and sticking to safe food practices reduces your odds of picking up salmonella on a trip.

For longer trips, the NHS suggests bringing a portable food‑thermometer. A quick check that chicken reaches 74 °C (165 °F) can be a lifesaver when you’re cooking in unfamiliar kitchens.

Additionally, consider enrolling in the CDC’s “Travelers’ Health” email alerts to receive real‑time outbreak notifications for the regions you plan to visit.

Home remedies for salmonella nausea during pregnancy and natural remedies with evidence

Nausea is common in both early pregnancy and salmonella infection. While you should never replace medical care with home tricks, a few gentle remedies can ease discomfort:

• Ginger tea: 1 g fresh ginger steeped in hot water for 5 minutes. Small studies show ginger reduces pregnancy‑related nausea without harming the fetus (American Pregnancy Association, 2021).
• BRAT diet: Bananas, rice, applesauce, toast—easy‑to‑digest foods that can calm an upset stomach.
• Hydration with electrolytes: Small sips of oral rehydration solution every 15 minutes.
• Probiotic yogurt: Contains live cultures that may help restore gut flora after antibiotics, though evidence is modest.

These remedies are supportive; if vomiting prevents you from staying hydrated, seek medical attention promptly.

Another evidence‑based option is peppermint oil capsules, which have been shown in a 2020 Cochrane review to reduce nausea in pregnancy when taken in low doses. Always discuss any supplement with your provider, especially if you are taking other medications.

For persistent nausea, a warm compress on the abdomen and slow, deep breathing can also provide relief without medication.

Difference between salmonella and listeria in pregnancy, testing options, and impact on breastfeeding

Both salmonella and listeria are food‑borne bacteria, but they differ in severity and treatment:

• Salmonella usually causes acute gastroenteritis; fever and diarrhea are common. Antibiotics are optional for healthy adults but often used in pregnancy.
• Listeria monocytogenes can cause meningitis and miscarriage. It often presents with flu‑like symptoms, not diarrhea, and requires immediate antibiotic therapy (ampicillin + gentamicin).

Testing:

• Stool culture for salmonella.
• Blood culture and, if pregnant, amniotic fluid testing for listeria when symptoms suggest infection.

Regarding breastfeeding, most antibiotics used for salmonella (azithromycin, ceftriaxone) are considered safe and pass into breast milk at low levels. Listeria infection itself can be transmitted through breast milk, but appropriate treatment eliminates the risk.

For mothers who are unsure whether a symptom points to salmonella or listeria, the CDC recommends a “rule of thumb”: diarrhea with blood leans toward salmonella, whereas a combination of fever, muscle aches, and no gastrointestinal upset leans toward listeria. Prompt lab testing settles the question.

Risk factors that increase your chance of salmonella during pregnancy

Not every pregnant person faces the same level of risk. Certain factors raise the odds of acquiring salmonella:

• Living in or traveling to regions with recent outbreak reports (as tracked by the CDC or NHS).
• Having a chronic condition that weakens immunity, such as diabetes or inflammatory bowel disease.
• Working in food‑service or handling raw animal products at home.
• Consuming a diet high in raw or undercooked animal products, especially without proper refrigeration.

Understanding these risk factors helps you prioritize preventive steps. For example, if you work as a home cook for a family, you might invest in a separate cutting board for raw poultry and a dedicated set of utensils for ready‑to‑eat foods.

Women who have a history of recurrent gastrointestinal infections should discuss a personalized food‑safety plan with their OB‑GYN early in pregnancy.

Testing for salmonella during pregnancy: what to expect at the lab

If your provider suspects salmonella, a stool sample is the first step. The sample is usually collected in a clean, leak‑proof container and sent to a certified laboratory. Results typically return within 48‑72 hours. A positive culture confirms the presence of Salmonella enterica and guides antibiotic choice.

In severe cases—especially if you have a high fever or signs of bloodstream infection—a blood culture may be ordered. This involves a small needle draw, and the lab looks for bacteria in the bloodstream. While blood cultures are less sensitive for salmonella than stool cultures, they are crucial for identifying invasive disease that could affect the placenta.

The NHS advises that you should refrain from taking probiotics or antibiotics for at least 48 hours before providing a stool sample, as these can interfere with accurate detection.

For those who need a rapid diagnosis, some hospitals now offer PCR‑based stool testing, which can return results within a few hours, though the cost and availability vary by region.

Nutrition and recovery: supporting your body after a salmonella episode

Recovering from salmonella while pregnant calls for a balanced approach that restores fluids, replenishes electrolytes, and supplies the nutrients your growing baby needs.

• Protein: Soft‑cooked lean meats, tofu, or well‑cooked beans provide amino acids for fetal tissue growth.
• Complex carbs: Oatmeal, sweet potatoes, and whole‑grain toast give steady energy without overloading the stomach.
• Healthy fats: Avocado, olive oil, and nut butters support hormone production and help absorb fat‑soluble vitamins.
• Hydration: In addition to water, add a pinch of salt and a splash of fruit juice to oral rehydration solutions for better electrolyte balance.

According to Harvard T.H. Chan School of Public Health, maintaining a diet rich in fiber (e.g., cooked carrots, peeled apples) can help normalize bowel movements after the infection clears.

Finally, schedule a follow‑up appointment with your OB‑GYN within 1‑2 weeks of recovery to ensure that your weight gain and lab values are on track.

Many women find that a gentle probiotic supplement, taken after completing antibiotics, can reduce lingering bloating, but always check with your provider first.

How to safely handle leftovers and reduce salmonella risk

Leftovers are a convenient way to stretch meals, but they can become a hidden source of salmonella if not stored or reheated properly. The CDC recommends cooling cooked foods to below 4 °C (40 °F) within two hours and storing them in shallow containers to speed up cooling.

When reheating, make sure the internal temperature reaches at least 74 °C (165 °F) before serving. A food‑grade thermometer is the most reliable way to verify this, especially for soups, stews, and casseroles that may have uneven heating.

Pregnant people should also avoid “room‑temperature” foods that sit out for longer than an hour, such as buffet salads or picnic spreads, as these environments can promote bacterial growth.

Labeling leftovers with the date prepared can help you keep track of the recommended 3‑day consumption window, reducing the temptation to eat food that may have become unsafe.

Salmonella risk for pregnant vegans and vegetarians

While vegans and vegetarians avoid animal products that are classic salmonella carriers, they can still encounter the bacteria through contaminated produce, sprouts, and processed plant‑based foods. Sprouted beans and alfalfa seeds have been linked to several outbreaks because the warm, moist conditions of sprouting are ideal for bacterial growth.

To minimize risk, buy pre‑packaged sprouts that have been treated with a food‑safety kill step, or better yet, avoid raw sprouts altogether. Wash all fresh produce under running water, and consider using a produce‑wash solution recommended by the FDA.

Plant‑based meat alternatives, such as soy “chicken” strips, should be cooked to the same internal temperature guidelines as animal meat (74 °C/165 °F) to ensure any potential contamination is eliminated.

Many pregnant vegans find that incorporating a variety of cooked legumes, grains, and fortified plant milks provides the necessary nutrients without increasing salmonella exposure.

Myth vs. fact

Myth: “If I’m pregnant, any salmonella infection will cause a miscarriage.”

Fact: Most salmonella infections do not lead to miscarriage. Severe fever in early pregnancy slightly raises risk, but prompt treatment mitigates it.

Myth: “I can’t eat any eggs at all while pregnant.”

Fact: Fully cooked eggs and pasteurized egg products are safe and provide valuable protein and choline for fetal brain development.

Myth: “Antibiotics are dangerous for my baby.”

Fact: Certain antibiotics, like azithromycin and ceftriaxone, are classified as safe in pregnancy and are often recommended for salmonella when needed.

Key takeaways

• Raw or undercooked eggs are a known source of salmonella—cook them thoroughly.
• Watch for fever ≥ 38 °C, diarrhea, and dehydration; call your provider promptly.
• Safe antibiotics (azithromycin, ceftriaxone) are available; avoid trimethoprim‑sulfamethoxazole after the first trimester.
• Practice strict food safety: cook poultry, avoid unpasteurized dairy, and separate raw meats from fresh produce.
• Outbreak updates are available on the CDC website; stay informed when traveling.
• Gentle home remedies (ginger tea, BRAT diet, electrolytes) can ease nausea, but don’t replace medical care.
• Know your personal risk factors and seek testing early if symptoms appear.
• Handle leftovers promptly, reheat to 74 °C (165 °F), and label containers with dates.
• Even plant‑based diets need the same cooking temperatures for processed meat alternatives.

Frequently asked questions

What are the signs of salmonella infection during pregnancy?

Key signs include fever ≥ 38 °C, watery diarrhea (sometimes with blood), abdominal cramps, and vomiting that prevents you from staying hydrated. If you have any of these, especially fever, contact your OB‑GYN.

Can salmonella cause miscarriage?

Salmonella rarely causes miscarriage. A high fever in the first trimester modestly raises the risk, but prompt treatment and fever control keep the chance low.

Is it safe to eat sushi while pregnant?

Only if the sushi is made with fully cooked fish or vegetarian ingredients. Raw seafood can harbor salmonella, listeria, and other pathogens, so it’s best to avoid it during pregnancy.

How long does it take to recover from salmonella in pregnancy?

Most people feel better within 4–7 days. Full recovery, including gut healing, may take up to two weeks. Stay hydrated and follow your provider’s advice.

Which antibiotics are recommended for salmonella in pregnant women?

Azithromycin is the first‑line oral antibiotic; ceftriaxone is used intravenously for severe cases. Both are considered safe (Category B) by the FDA and recommended by ACOG.

Can I get salmonella from a pet cat or dog while pregnant?

Pets can carry salmonella, especially reptiles and birds, but transmission from cats or dogs is rare. Practice good hygiene—wash hands after handling pet waste or food bowls—to minimize any risk.

Should I stop taking probiotics if I’m being treated for salmonella?

Probiotics are generally safe and may help restore gut flora after antibiotics. Discuss any supplement with your provider, but they are not contraindicated.

Are over‑the‑counter anti‑diarrheal meds safe during pregnancy?

Most OTC anti‑diarrheal medicines, such as loperamide, are not routinely recommended for pregnant people because they can slow gut motility and affect nutrient absorption. The NHS advises using them only under a provider’s direction.

Does getting a flu shot protect me from salmonella?

No. The influenza vaccine protects against the flu virus, not bacterial infections like salmonella. However, staying up to date on all vaccines reduces overall illness burden, which can help you maintain a stronger immune system during pregnancy.

Can I eat pre‑sliced deli meat that says “ready to eat”?

Even “ready‑to‑eat” deli meats can harbor salmonella if they have been stored too long. Reheat them until steaming hot (74 °C/165 °F) before eating to ensure safety.

Will a salmonella infection affect my prenatal blood test results?

Typical prenatal labs (CBC, CMP) may show a mild rise in white blood cells during infection, but this does not usually alter the overall interpretation of your pregnancy health. Your provider will consider any temporary changes in context.

When to see a doctor / specialist

Call your OB‑GYN or go to urgent care now if you have:

• Fever ≥ 38 °C lasting more than 24 hours
• Severe dehydration (dry mouth, dizziness, urine < 150 mL/day)
• Blood in stool
• Persistent vomiting that prevents fluid intake
• Abdominal pain that’s sharp or worsening

In these cases, an infectious‑disease specialist may be consulted, especially if you have a compromised immune system. This article is for informational purposes only and does not replace personalized medical advice.
