18 Foods to Avoid During Pregnancy

Pregnancy comes with enough surprises already. Your snack choices do not need to audition for the role of “unexpected plot twist.” While most foods are perfectly fine in a balanced pregnancy diet, some are better avoided because they can carry harmful bacteria, parasites, or chemicals that may affect you and your baby. In other words, this is not the season for culinary gambling.

If you have been Googling foods to avoid during pregnancy, you are not alone. It is one of the most common questions in prenatal care, and for good reason. Pregnancy changes your immune response, which means a food that once seemed harmless can become a bigger deal. The goal is not to make eating stressful. It is to make it safer, smarter, and a whole lot less confusing.

This guide breaks down 18 foods to avoid during pregnancy, why they matter, and what to choose instead. Some items are absolute no-gos. Others are more like “not unless it is cooked, pasteurized, or handled safely.” That distinction matters, especially if you are trying to eat well without turning every grocery trip into a detective show.

Why Food Safety Matters More During Pregnancy

During pregnancy, food safety is not just about avoiding a stomachache. Certain germs, including Listeria, Salmonella, and E. coli, can cause more serious illness in pregnant women and can sometimes affect the fetus as well. That is why pregnancy food safety advice focuses heavily on avoiding foods that are raw, undercooked, unpasteurized, or likely to sit around in cold storage long enough to invite trouble.

The good news is that the list is manageable. You do not need a joyless menu of dry toast and iceberg lettuce. You just need to know where the real risks are hiding.

18 Foods to Avoid During Pregnancy

1. High-Mercury Fish

Fish can be excellent during pregnancy, but not all fish are created equal. Some species contain too much mercury, which can affect a baby’s developing brain and nervous system. The big offenders include shark, swordfish, king mackerel, marlin, orange roughy, tilefish, and some bigeye tuna.

Safer swap: Choose lower-mercury options like salmon, shrimp, pollock, trout, sardines, or canned light tuna in sensible portions.

2. Fish From Local Waters Without Checking Advisories

Catching your own dinner sounds wholesome and cinematic, but local fish can sometimes contain contaminants depending on where they were caught. If there is no local advisory, it is smart to be cautious rather than treating mystery lake bass like a prenatal superfood.

Safer swap: Check local fish advisories first, or stick with commercially sold low-mercury fish.

3. Raw Fish

Raw fish dishes such as sushi, sashimi, and ceviche may contain bacteria or parasites. Pregnancy is not the ideal time to test whether your immune system enjoys a challenge. Even trendy, expensive, beautifully plated raw fish is still raw fish.

Safer swap: Go for cooked sushi rolls, baked salmon bowls, or shrimp tempura rolls if you want the sushi experience without the risk.

4. Raw Shellfish

Raw oysters, clams, mussels, and scallops are another category to skip. Shellfish can carry harmful germs, and because they filter water, they can also pick up contaminants from their environment. That seaside platter may look glamorous, but pregnancy is a better time for steamed, grilled, or fully cooked seafood.

Safer swap: Choose cooked crab, steamed shrimp, or fully cooked scallops.

5. Refrigerated Smoked Seafood

Lox, nova-style salmon, kippered fish, and other refrigerated smoked seafood products can carry Listeria. The issue is not necessarily the fish itself; it is the cold, ready-to-eat nature of the product. When a food can sit in the refrigerator and still support bacterial growth, it earns a place on the pregnancy caution list.

Safer swap: Canned or shelf-stable smoked seafood is generally safer, and smoked seafood cooked into a casserole or hot dish is a better choice.

6. Undercooked Meat and Poultry

Rare burgers, pink chicken, and undercooked pork are all poor pregnancy dinner guests. They may harbor bacteria or parasites that can make you seriously ill. This is especially important with ground meat, which needs to be cooked thoroughly because bacteria can be mixed throughout.

Safer swap: Cook meat and poultry all the way through, and use a food thermometer if you want certainty instead of wishful thinking.

7. Cold Deli Meats and Hot Dogs

Deli turkey, ham, salami, and hot dogs are common cravings, but they can be risky if eaten straight from the package or deli counter. These ready-to-eat meats can carry Listeria, which is one of the main reasons they show up on nearly every what not to eat when pregnant list.

Safer swap: Heat them until steaming hot before eating. That extra minute in the microwave is not glamorous, but it is practical.

8. Refrigerated Pâté and Meat Spreads

Refrigerated pâté and meat spreads may also carry Listeria. They are often overlooked because they do not scream “high risk” the way raw oysters do, but they are still on the avoid list.

Safer swap: Shelf-stable canned versions are a safer option if you really want them.

9. Store-Made Deli Salads

Chicken salad, tuna salad, egg salad, coleslaw, and potato salad from deli cases can be risky because they are prepared in bulk and stored cold. That combination gives bacteria more opportunity to grow than anyone wants during pregnancy.

Safer swap: Make your own at home with fresh ingredients, clean hands, and a refrigerator that is doing its job.

10. Raw or Runny Eggs

Soft-scrambled eggs, sunny-side-up eggs, and any egg dish with a runny center can increase the risk of Salmonella. Eggs are nutritious, but during pregnancy they should be fully cooked. Think firm whites and yolks, not “Instagram brunch aesthetic.”

Safer swap: Hard-boiled eggs, fully cooked omelets, or scrambled eggs cooked through.

11. Foods Made With Raw Eggs

The egg risk does not end at breakfast. Homemade Caesar dressing, hollandaise sauce, fresh mayonnaise, mousse, tiramisu, royal icing, eggnog, and some homemade desserts may use raw eggs. So can raw cake batter and old-fashioned cookie dough recipes.

Safer swap: Choose products made with pasteurized eggs, or make homemade versions with pasteurized egg products.

12. Unpasteurized Milk, Yogurt, and Ice Cream

Unpasteurized dairy products can carry harmful germs, including Listeria. Pasteurization is one of those wonderfully unexciting modern processes that deserves a standing ovation during pregnancy. If the label does not clearly say “pasteurized,” do not assume it is fine.

Safer swap: Choose pasteurized milk, yogurt, and ice cream from reputable sources.

13. Unheated Queso Fresco-Type or Unpasteurized Soft Cheeses

Soft cheeses can be tricky. Some are safe if made from pasteurized milk, while others are riskier, especially fresh queso fresco-style cheeses or any cheese made with unpasteurized milk. Brie, Camembert, blue-veined cheeses, queso blanco, and queso fresco deserve extra label-reading attention.

Safer swap: Pick cheeses clearly labeled as made with pasteurized milk, or enjoy them heated until steaming hot when appropriate.

14. Unpasteurized Juice or Cider

Fresh-pressed sounds healthy, but if the juice or cider is unpasteurized, it may carry harmful bacteria. Farmers market charm does not automatically equal food safety. A glass of raw cider is not worth the gamble.

Safer swap: Choose pasteurized juice and cider, or boil unpasteurized cider before drinking if that fits the product and recipe.

15. Raw Sprouts

Alfalfa, clover, radish, mung bean, and other raw sprouts are surprisingly risky. Bacteria can grow during the sprouting process, and washing does not reliably solve the problem. This is one of those foods that looks innocent enough to babysit your houseplants, but it still makes the no-thanks list during pregnancy.

Safer swap: Eat sprouts only when cooked thoroughly until steaming hot, or replace them with lettuce, cabbage, or sliced cucumbers for crunch.

16. Unwashed Fruits and Vegetables

Produce is healthy, but it still needs washing. Unwashed fruits, salad greens, herbs, and vegetables can carry germs from soil, water, handling, or transportation. Bagged greens are convenient, but an extra rinse can add peace of mind depending on the product and your provider’s advice.

Safer swap: Wash produce well under running water before eating, cutting, or cooking.

17. Cut Melon Left Out Too Long

Whole melon is one thing; cut melon is another. Once melon is sliced, bacteria can spread from the rind to the edible part. If cut melon has been sitting out for more than two hours, or longer than one hour in very hot weather, it belongs in the trash, not in your fruit bowl fantasy.

Safer swap: Eat melon freshly cut or keep it refrigerated and use it within a reasonable time.

18. Raw Dough and Batter

Yes, this includes the “just one little taste” of cookie dough. Raw dough and batter may contain raw eggs, but even egg-free dough can still be risky because raw flour can carry harmful bacteria. Pregnancy is not the time to lick the spoon and hope for the best.

Safer swap: Bake first, snack second. Edible dough products made specifically to be eaten raw are the exception if they are produced safely.

Important Pregnancy Drink Notes

Even though this article focuses on foods, two drink-related rules deserve their own spotlight. First, avoid alcohol completely during pregnancy. There is no known safe amount, no safe time, and no safe type. Second, limit caffeine. Many experts recommend keeping caffeine under about 200 milligrams a day, which means coffee, tea, soda, chocolate, and especially energy drinks should all be counted honestly rather than with magical thinking.

How to Make Pregnancy Eating Easier, Not Scarier

A smart pregnancy diet is less about memorizing a horror list and more about using a few reliable habits. Read labels. Look for the word pasteurized. Cook animal proteins thoroughly. Reheat deli meats until steaming. Wash produce. Keep cold foods cold and hot foods hot. If something has been sitting out too long at a buffet, baby shower, office party, or family cookout, let it go. Your future self will thank you.

It also helps to focus on what you can enjoy: low-mercury fish, cooked eggs, pasteurized dairy, fully cooked meats, washed produce, whole grains, beans, nuts, and nutrient-dense snacks that actually keep you full. Pregnancy is demanding enough without adding hunger and confusion to the mix.

Conclusion

Knowing the 18 foods to avoid during pregnancy can take a lot of stress out of meal planning. The main risks come from foods that are raw, undercooked, unpasteurized, high in mercury, or prone to bacterial growth during cold storage. Fortunately, most of them have easy substitutes. You usually do not need to give up the entire category, just the risky version of it.

If you are ever unsure, ask your OB-GYN, midwife, or prenatal dietitian. Pregnancy nutrition should feel informed, not fearful. You are not aiming for perfection. You are aiming for safer choices, consistent habits, and fewer opportunities for your lunch to become a medical event.

Real-Life Experiences With Pregnancy Food Rules

Here is the part nobody tells you when they hand you a pregnancy food list: the tricky part is not reading it, it is living it. In real life, avoiding risky foods during pregnancy is rarely about dramatic cravings for champagne and oysters under a chandelier. More often, it looks like standing in your kitchen at 7:12 a.m. wondering whether the turkey sandwich you loved last month has now become your enemy. It looks like reading a cheese label three times in the grocery aisle while another shopper quietly reaches around you for perfectly normal cheddar.

Many pregnant women describe the first few weeks as the strangest combination of hunger, nausea, and suspicion. Foods you used to love suddenly smell suspicious. Foods you never cared about become the only thing that sounds tolerable. Then you find out that the one item you can currently imagine eating is a cold deli sub, which feels deeply unfair and a little personal.

Social situations can make things even more awkward. At brunch, everyone else is ordering runny eggs, smoked salmon, and fancy lattes large enough to require zoning approval. Meanwhile, you are asking whether the eggs can be fully cooked, whether the cheese is pasteurized, and whether there is any chance the mocktail has less mystery and more ingredient transparency. You may feel high-maintenance. You are not. You are being careful.

Family advice adds another layer. Someone will almost certainly say, “I ate that with all my pregnancies and my kids turned out fine.” That may be true, but it is not a nutrition policy. Pregnancy advice is based on risk reduction, not nostalgia. The fact that someone once survived a questionable potato salad at a summer picnic does not make the potato salad a prenatal vitamin.

There is also the emotional side of food restriction. Pregnancy already asks a lot of the body. When you are tired, queasy, and trying to do everything right, even a small food rule can feel huge. That is why flexibility matters. If you cannot have the cold deli sandwich, have the hot grilled one. If sushi sounds amazing, get a cooked roll. If soft cheese is on the menu, read the label and choose a pasteurized option. Safe swaps are not consolation prizes. They are how real people make real life work.

Over time, most women settle into a rhythm. They learn which brands are pasteurized, which coffee order fits the caffeine limit, and which leftovers are still worth eating. The anxiety usually softens once the rules become habits. And that is the real takeaway: pregnancy food safety is not about eating fearfully for nine months. It is about making a series of practical choices that protect your baby while still leaving room for enjoyable meals, normal routines, and the occasional dessert that has actually been baked first.
