Pregnancy comes with enough surprises (hello, sudden hatred of your favorite perfume) without adding “mystery food poisoning” to the plot. The good news: most “avoid” advice isn’t about banning joyit’s about lowering risk from foodborne germs, mercury, and ingredients that can affect fetal development.

This guide pulls from widely used U.S. medical and food-safety recommendations (think: OB-GYN guidance plus federal food safety agencies) and turns them into something you can actually use in a grocery store aislewithout needing a biology degree or a stress nap.

Before we jump in: “avoid” sometimes means “avoid unless prepared safely”

Some items on this list are total no-go (like alcohol). Others are “no-go in the risky form,” but perfectly fine when cooked, pasteurized, or handled correctly. When in doubt, ask your prenatal providerespecially if you’re immunocompromised, have pregnancy complications, or are unsure about a specific product.

The Big 10: Foods and Drinks to Avoid During Pregnancy

1. Alcohol
2. High-mercury fish
3. Raw or undercooked seafood (including raw oysters)
4. Undercooked meat and poultry
5. Raw or undercooked eggs (and foods made with them)
6. Unpasteurized milk, soft cheeses, and unpasteurized juices
7. Deli meats, hot dogs, and premade deli salads (unless reheated properly)
8. Refrigerated smoked seafood and refrigerated pâté/meat spreads
9. Raw sprouts
10. High-caffeine drinks (and energy drinks)avoid “over the limit” days

1) Alcohol

Bottom line: There’s no proven safe amount, type, or timing of alcohol during pregnancy.

Why it’s risky

Alcohol can pass to the baby and is linked to fetal alcohol spectrum disorders (FASDs), which can cause lifelong physical, learning, and behavioral challenges. The tricky part is that risk isn’t neatly predictableso the safest approach is none at all.

What to do instead

• Try alcohol-free beer/wine only if you trust the brand and your provider says it’s okaysome products still contain small amounts.
• Mocktail upgrades: sparkling water + citrus + mint, or ginger beer + lime + bitters-free “aromatics.”
• If you drank before you knew you were pregnant, don’t spiral. Bring it up at your next appointment for personalized guidance.

2) High-mercury fish

Avoid fish known to be highest in mercury, such as shark, swordfish, king mackerel, marlin, orange roughy, tilefish (Gulf of Mexico), and bigeye tuna.

Why it’s risky

Mercury can affect fetal brain and nervous system development. Fish is still a nutritional win overalljust not the high-mercury kind. This is a “choose wisely” situation, not a “never eat seafood again” situation.

How to make it safe instead

• Choose lower-mercury seafood like salmon, shrimp, pollock, cod, tilapia, sardines, and trout.
• A common guideline is aiming for 8–12 ounces per week of lower-mercury seafood (your provider may tailor this based on your diet and local advisories).
• When ordering tuna, note that some tuna types are higher-mercury than others; ask what kind it is if you can.

3) Raw or undercooked seafood (including raw oysters)

That means sushi/sashimi made with raw fish, plus raw oysters, clams, mussels, and similar shellfish.

Why it’s risky

Raw or undercooked seafood can carry germs and parasites that can hit harder during pregnancy. Foodborne illness can cause dehydration and fevertwo things your body (and baby) would rather not audition for.

How to make it safe instead

• Choose sushi made with fully cooked seafood (shrimp tempura, cooked crab, eel) or vegetarian rolls.
• Order shellfish only when thoroughly cooked (steamed clams/mussels until opened; cooked shrimp until opaque and firm).
• Skip the “lightly seared” trendpregnancy is not the time for culinary roulette.

4) Undercooked meat and poultry

Avoid rare/undercooked burgers, pink chicken (yes, that’s a thing), and “just a little under” anything that used to moo, oink, or cluck.

Why it’s risky

Undercooked meat and poultry can carry bacteria (like Salmonella and E. coli) and parasites (like Toxoplasma), which can be especially harmful in pregnancy.

How to make it safe instead

Use a food thermometer. Guessing doneness by vibes is how we got half the internet’s “I got food poisoning” stories.

Quick temperature cheat sheet

5) Raw or undercooked eggs (and foods made with them)

This includes runny yolks, homemade cookie dough, and foods made with raw egg like some Caesar dressings, hollandaise, tiramisu, and homemade mayo.

Why it’s risky

Raw eggs can carry Salmonella. During pregnancy, even a “mild” stomach bug can be more disruptive because dehydration and fever matter more.

How to make it safe instead

• Cook eggs until both the white and yolk are firm.
• Use pasteurized eggs for recipes that traditionally use raw egg (ask your provider if you’re unsure which brands are appropriate).
• Buy dressings and sauces from reputable brands that use pasteurized ingredients.

6) Unpasteurized milk, soft cheeses, and unpasteurized juices

Avoid raw milk products and soft cheeses made from unpasteurized milk (or with unclear labeling). Also be cautious with unpasteurized juices/ciders.

Why it’s risky

Unpasteurized products can carry germs like Listeria, which is especially concerning during pregnancy because it can cross the placenta and lead to serious complications.

How to make it safe instead

• Check labels for the word “pasteurized”.
• Many soft cheeses are fine if made with pasteurized milkjust confirm the label.
• If you’re eating out, ask whether cheeses and dairy are pasteurized (yes, it can feel awkward; no, you will not be the weirdest customer they get that day).

7) Deli meats, hot dogs, and premade deli salads (unless reheated properly)

This includes cold cuts, deli turkey, bologna, hot dogs, and premade deli salads like chicken salad, tuna salad, ham salad, coleslaw, and potato salad.

Why it’s risky

Ready-to-eat refrigerated foods can be linked to Listeria. Here’s the annoying part: Listeria can grow even in the fridge. (Your refrigerator is a cold box, not a magical force field.)

How to make it safe instead

• Heat deli meats and hot dogs until steaming hot (a common target is about 165°F).
• Choose freshly cooked proteins (grilled chicken, roasted turkey you cooked yourself).
• Make deli-style salads at home with safe handling, then refrigerate promptly and eat within a reasonable window.

8) Refrigerated smoked seafood and refrigerated pâté/meat spreads

This includes refrigerated smoked salmon labeled “lox,” “nova-style,” “kippered,” or “smoked,” plus refrigerated pâté or meat spreads from the deli case.

Why it’s risky

These refrigerated ready-to-eat foods are higher risk for Listeria. The concern is not “fish is bad,” but “refrigerated smoked fish can be risky unless it’s cooked.”

How to make it safe instead

• Choose canned or shelf-stable smoked seafood (and refrigerate after opening).
• Use smoked fish as an ingredient in a fully cooked dish (like a casserole or hot pasta dish).
• Swap refrigerated pâté for shelf-stable versions that don’t require refrigeration before openingif you want it at all.

9) Raw sprouts

Examples include alfalfa, clover, mung bean, radish, and mixed “sandwich sprouts.”

Why it’s risky

Sprouts grow in warm, humid conditionsexactly what certain bacteria love. Germs can be inside the seed, which makes them difficult to wash off thoroughly.

How to make it safe instead

• Eat sprouts only when cooked until steaming hot.
• When ordering sandwiches and bowls, ask for “no sprouts,” or check ingredient lists (sprouts are sneaky like that).
• Get crunch elsewhere: shredded cabbage, cucumber, bell pepper, or toasted nuts (if tolerated).

10) High-caffeine drinks (and energy drinks)avoid “over the limit” days

You don’t necessarily need to avoid caffeine completely, but many U.S. experts recommend keeping total caffeine under about 200 mg per day during pregnancy.

Why it’s risky

Caffeine crosses the placenta, and high intakes have been associated in some research with adverse outcomes. Because the science isn’t perfectly uniform, most guidance lands on a conservative daily cap. Energy drinks are extra tricky because they can be high in caffeine and may include other stimulants or large sugar loads.

How to make it safe instead

• Track your total caffeine from coffee, tea, soda, chocolate, and some “energy” products.
• Common reference point: roughly one 12-ounce cup of coffee can land near the daily recommendation (but it varies widely by brand and brew).
• Try half-caf, smaller sizes, or switching one cup to decaf.

Food-safety habits that protect you beyond the “avoid” list

Even if you never touch a deli sandwich again (a brave sacrifice), food safety still matters at home and when eating out.

Smart habits that pay off

• Clean: Wash hands, utensils, and cutting boardsespecially after handling raw meat.
• Separate: Keep raw meat separate from produce and ready-to-eat foods to prevent cross-contamination.
• Cook: Use a thermometer for meats, leftovers, and casseroles.
• Chill: Refrigerate perishables promptly; don’t let cut fruit sit out at room temperature for long stretches.

If you accidentally ate something on the list

First: breathe. One exposure doesn’t automatically mean harm. Watch for symptoms like fever, vomiting, diarrhea, severe body aches, or dehydration. If you have symptomsor you’re worriedcall your prenatal provider. They’d much rather reassure you early than meet you later in a panic.

Conclusion

Pregnancy nutrition advice can feel like a scavenger hunt where every clue is “read the fine print.” But the goal is simple: avoid foods and drinks more likely to carry harmful germs, limit exposure to mercury, and steer clear of substances that can impact fetal development.

If you remember nothing else, remember this: pasteurized + fully cooked + safely handled gets you most of the way there. And yesyour cravings will still try to negotiate. You’re allowed to negotiate back (with a thermometer and a label check).

Real-Life Experiences Related to Avoiding These Foods and Drinks (Extra)

Most people expect pregnancy cravings to be cutepickles, ice cream, the occasional dramatic weeping over a croissant. What they don’t always expect is how specific the cravings can get, and how often those cravings go straight for items on the “maybe not right now” list. A very common experience is the deli sandwich dilemma: you want the cold turkey sub you’ve loved since college, but now you’re standing in the kitchen Googling “steaming hot means… how hot, exactly?” Many pregnant people end up doing a compromise: heating the meat until it’s piping hot, letting it cool, then rebuilding the sandwich at home with fresh toppings. It’s not quite the same, but it often scratches the itch without the extra risk.

Another real-world moment: becoming an accidental cheese label detective. People report spending more time reading dairy labels than reading texts from their friends. You’ll see it happen: you pick up brie, you panic, then you find “made with pasteurized milk” and feel like you just solved a mystery novel. (Plot twist: you did. The murderer was “unclear labeling.”) That same label-reading skill often spreads to juices, ciders, and even “health drinks” from farmers markets, where pasteurization isn’t always obvious. Many pregnant people learn to ask one simple question: “Is this pasteurized?”and they get comfortable asking it everywhere.

Then there’s the coffee negotiation era. Some people decide to quit caffeine completely; others keep one small cup and treat it like a sacred morning ritual. A common strategy is “front-loading”: having caffeine early, then switching to decaf or herbal options later. The catch is that “herbal” doesn’t automatically mean “pregnancy-friendly,” so many people stick to safer basics (like ginger or peppermint teas) and check with their provider about anything medicinal-sounding. And energy drinks? A lot of pregnant people describe those as the easiest “no,” mostly because they’re often high in caffeine and can make jitters and heartburn feel like a competitive sport.

Eating out can also feel like a mini social experiment. People report learning to ask restaurant questions in a calm, friendly way: “Is that egg fully cooked?” “Is the cheese pasteurized?” “Can you make that without sprouts?” The first time feels awkward; the third time feels normal. Some even develop a personal “safe order” playbooklike choosing grilled proteins, cooked vegetables, and hot soups (as long as they’re piping hot) to lower food-safety worries while still enjoying meals out.

Lastly, many people share that the most helpful experience is realizing this isn’t about being perfectit’s about being consistent. Pregnancy comes with enough pressure; food shouldn’t become a daily guilt contest. The wins are practical: keeping a thermometer in the kitchen, heating deli meats when cravings hit, choosing lower-mercury fish, and avoiding alcohol. If you do those things most of the time, you’re stacking the odds in your favorwithout turning every meal into a dissertation defense.
