During pregnancy, expectant mothers become acutely aware of the importance of nutrition, not just for their own well-being but crucially for their developing baby. It’s a period when certain dietary choices can carry significant risks, ranging from serious foodborne illnesses like Listeria, Salmonella, and Toxoplasma, to substances that can readily cross the placental barrier and impact fetal development. To help navigate these crucial decisions, we’ve compiled a comprehensive list of 10 key food and drink categories that leading global health organizations – including the CDC, ACOG, WHO, NHS, March of Dimes, and the American Pregnancy Association (based on their 2025 guidelines) – consistently advise against or recommend strictly limiting. Adhering to these guidelines is a vital step in ensuring a healthy pregnancy journey.
1. Raw or Undercooked Meats, Poultry, Eggs, and Seafood
- Potential Hazards: Consuming these items carries a high risk of exposure to harmful bacteria and parasites such as Salmonella, E. coli, Toxoplasma, and Listeria. These pathogens can cause severe illness in pregnant individuals and potentially lead to serious complications for the baby.
- Items to Exclude: This category includes foods like rare or medium-rare steaks, all forms of sushi or sashimi (raw fish), uncooked shellfish such as oysters, clams, and mussels, and any dishes containing raw or partially cooked eggs, like runny yolks, homemade Caesar salad dressing, or raw cookie dough.
- Safe Preparation: To eliminate these risks, ensure all meat and poultry are cooked thoroughly to an internal temperature of at least 165°F (74°C). Eggs should be cooked until both the yolk and white are firm. Fish should reach an internal temperature of 145°F (63°C).
2. Deli Meats, Hot Dogs, Cold Cuts, and Cured Meats (Unless Steaming Hot)
- Primary Concern: The main threat with these products is Listeria, a bacterium known for its ability to multiply even in refrigerated environments. Listeriosis, the infection caused by Listeria, can be particularly dangerous during pregnancy, potentially leading to miscarriage, premature birth, or severe infection in the newborn.
- Foods to be Cautious Of: This includes various processed meats such as pre-packaged turkey and ham slices, hot dogs, salami, prosciutto, bologna, pepperoni, and pâté.
- Preparation for Safety: If you choose to consume these items, it is crucial to heat them until they are steaming hot throughout, reaching an internal temperature of 165°F (74°C), to effectively kill any lurking bacteria.
3. Soft Cheeses Made from Unpasteurized Milk

- Significant Risk: Soft cheeses, especially those made from unpasteurized (raw) milk, pose a substantial risk of Listeria contamination. Their high moisture content and lower acidity create an ideal breeding ground for this dangerous bacterium.
- Varieties to Avoid: This list encompasses popular soft cheeses such as Brie, Camembert, and blue-veined varieties like Roquefort, Gorgonzola, and Stilton. Also included are fresh Mexican cheeses like queso fresco, queso blanco, and panela, along with feta and goat cheese (chèvre), unless their labels explicitly state they are made from pasteurized milk.
- Recommended Options: Opt for hard cheeses like cheddar, Swiss, or Parmesan, which are generally safe. Many soft cheeses are also available in pasteurized versions; always check the label for confirmation.
4. Unpasteurized Juices and Ciders
- Health Hazards: Unpasteurized juices and ciders can harbor harmful bacteria, including E. coli and Salmonella, among others. Pasteurization is a heat treatment process designed to eliminate these pathogens, making unpasteurized versions a potential source of foodborne illness.
- Common Examples: Be wary of fresh-squeezed juices purchased from farmers’ markets, unpasteurized apple cider, and certain types of raw kombucha, which may not undergo sufficient pasteurization.
- Safer Choices: Always choose juices that are clearly labeled “pasteurized.” This simple check ensures that the product has been treated to remove harmful bacteria.
5. Fish with High Mercury Content
- Developmental Concerns: High levels of mercury can be detrimental to a developing fetus, specifically impairing the brain and nervous system. Mercury accumulates in fish, and consuming certain species can lead to adverse neurological effects in infants.
- Fish to Strictly Avoid: Completely eliminate shark, swordfish, king mackerel, tilefish (especially from the Gulf of Mexico), bigeye tuna, and marlin from your pregnancy diet due to their exceptionally high mercury content.
- Moderate Consumption: Albacore (white) tuna should be limited to no more than 6 ounces per week.
- Excellent Safe Options: Many fish are low in mercury and provide beneficial omega-3 fatty acids. These include salmon, sardines, shrimp, cod, tilapia, and canned light tuna (which can be consumed up to 12 ounces per week).
6. Alcohol (Absolutely No Safe Amount)
- Profound Risks: The consumption of alcohol during pregnancy carries the risk of Fetal Alcohol Spectrum Disorders (FASD), a range of permanent and devastating birth defects. These can manifest as lifelong physical, behavioral, and learning challenges for the child. There is no known safe amount or type of
