Top Foods to Avoid During Pregnancy: Essential Safety Guide
Smart food choices during pregnancy reduce infection risks, avoid harmful exposures, and support fetal growth. This guide flags foods to avoid, items to limit, and safer swaps so you can eat confidently. Emphasize moderation and food safety, and adjust as your needs evolve. Use the sections below for quick reminders on what to skip and what to choose instead.
Why Some Foods Are Risky in Pregnancy
Pregnancy alters the immune system, making foodborne infections like listeria, salmonella, and toxoplasma more dangerous and increasing risks such as miscarriage, preterm birth, and severe newborn illness. Knowing which foods to avoid helps prevent these complications.
Non-infectious risks matter, too. Limit high-mercury fish to protect fetal brain and nervous system development, and avoid excess preformed vitamin A (retinol) from liver and certain supplements due to birth defect risks. Aim for balanced nutrition—get needed nutrients without extremes—by learning what to eat and what to avoid during pregnancy.
Seafood and Fish: Safer Choices and What to Skip
Fish provides protein and omega-3s, but it’s crucial to know the fish to avoid during pregnancy. High-mercury fish to skip include shark, swordfish, king mackerel, marlin, tilefish (Gulf of Mexico), orange roughy, and bigeye tuna. These are not safe in pregnancy due to mercury exposure.
Avoid raw or undercooked seafood. When considering sushi during pregnancy, choose rolls made with fully cooked fish (like tempura shrimp or cooked salmon) or vegetarian options only. Skip raw oysters, clams, ceviche, and refrigerated smoked fish (such as lox) unless heated until steaming. Also avoid high-mercury species in sushi.
Safer, low-mercury choices include salmon, sardines, trout, pollock, cod, tilapia, shrimp, crab, and canned light tuna. Aim for 8–12 ounces weekly in 2–3 cooked meals, and limit albacore (white) tuna to 4 ounces per week. Properly cooked, these options are not fish to avoid during pregnancy and fit well with safe sushi during pregnancy guidelines.
Meat, Poultry, Deli Items, and Eggs
During pregnancy, prevent foodborne illness by cooking meats fully and handling ready-to-eat items safely.
- Cook to safe temperatures: poultry and leftovers 165°F (74°C); ground meats 160°F (71°C); whole cuts 145°F (63°C) with a 3-minute rest.
- Avoid undercooked meats, including pink burgers, poultry with red juices, and runny sausages.
- Deli meats and hot dogs may carry listeria—reheat until steaming just before eating; skip pâtés and refrigerated meat spreads (shelf-stable canned is safer).
- Keep perishables at or below 40°F (4°C); discard food left out over 2 hours (1 hour if above 90°F/32°C).
- For eggs, avoid raw or undercooked dishes (e.g., homemade mayo, cookie dough, hollandaise, Caesar dressing, tiramisu); cook eggs until whites and yolks are firm or use pasteurized eggs for lightly cooked/uncooked recipes.
Dairy, Soft Cheeses, and Unpasteurized Foods
Unpasteurized milk and products made from it may harbor listeria. What foods to avoid during pregnancy in this category include raw milk and soft cheeses made from unpasteurized milk, such as some brie, camembert, blue-veined cheeses, queso fresco, queso blanco, panela, and unpasteurized feta. Choose pasteurized milk, yogurt, and cheese; check labels for “pasteurized.” These are common pregnancy foods to avoid if unpasteurized.
If you avoid dairy, choose fortified alternatives like soy, almond, or oat beverages and look for calcium and vitamin D. Keep dairy cold, follow use-by dates, and discard items with off smells or textures to steer clear of foods not safe during pregnancy. This supports what to eat and what not to eat during pregnancy with safe swaps and reinforces what not to eat when pregnant for dairy choices.
Drinks, Caffeine, and Supplements
- Alcohol: no safe amount in pregnancy
- Skip wine, beer, spirits
- Try sparkling water + fruit or pasteurized mocktails
- Caffeine limit: ~200 mg/day (focus on coffee during pregnancy)
- Count coffee, tea, soda, energy drinks, chocolate
- Rough guide: brewed coffee (8 oz) 80–100 mg; black tea 40–50 mg; energy drink 80–150 mg/serving
- Use supplements carefully
- Avoid high‑dose vitamin A (retinol) and fish liver oils
- Omega‑3 fish oil may help—pick purified products; confirm with your provider
Quick Reference: Pregnancy Foods to Avoid
| Foods to Avoid During Pregnancy | Safer Alternatives |
|---|---|
| High mercury fish (shark, swordfish, marlin, bigeye tuna, tilefish, king mackerel, orange roughy) | Salmon, trout, sardines, pollock, cod, tilapia, shrimp, canned light tuna |
| Raw or undercooked seafood; sushi with raw fish; refrigerated smoked fish | Fully cooked fish and shellfish; smoked fish heated until steaming |
| Raw or undercooked meat and poultry; deli meats not reheated; pâtés | Well-cooked meats; deli meats reheated until steaming; canned pâtés |
| Unpasteurized milk, juices, and soft cheeses made with raw milk | Pasteurized milk, yogurt, cheese; pasteurized juices |
| Raw or partially cooked eggs and foods made with them | Fully cooked eggs; recipes using pasteurized eggs |
| Alcohol; excessive caffeine | Alcohol-free mocktails; keep caffeine near the 200 mg daily limit |
Timing Matters: First and Third Trimester Tips
Key foods to avoid in first trimester: high-mercury fish, unpasteurized dairy, raw or undercooked meats, and alcohol—early development is sensitive. For foods to avoid in third trimester, keep avoiding the same items and be extra careful with deli meats, soft cheeses, and leftovers to reduce listeria risk as your due date nears.
Food Safety and When to Seek Care
- Wash hands and produce
- Keep raw and ready-to-eat foods separate; use different cutting boards
- Cook to safe temperatures
- Refrigerate within 2 hours (1 hour if hot)
- Reheat leftovers until steaming
These steps lower foodborne risks in pregnancy.
- Choose well-cooked, pasteurized foods; pick low-mercury fish
- Limit caffeine; follow coffee during pregnancy guidance
- Seek care for fever, vomiting, severe diarrhea, or less fetal movement after eating
- Ask your provider about foods and drinks to avoid and trimester-specific advice
