What Can’t You Eat While Pregnant? Start With 4 Questions
Most pregnancy food rules come down to four questions, not fifty rules. Ask them of whatever is in front of you and the long list of “don’ts” becomes a short list of swaps — and almost nothing leaves your plate for good.
US guidance flags unheated deli meats and refrigerated pâté; raw-milk dairy and certain soft cheeses; raw seafood and refrigerated smoked fish; high-mercury fish; raw eggs and sprouts; and alcohol. The details matter: pasteurized feta is different from unheated queso fresco, and washed produce is different from premade deli salad. Ask four questions about the food in front of you: Is it fresh? Is it cooked? Is it pasteurized? How much?
No list covers every label you’ll pick up, and the guidance keeps shifting. So the more durable tool is four questions you can run on anything that isn’t named above:

Why does a food get flagged in pregnancy?
Pregnancy increases the risk of some foodborne illnesses. Certain infections can also affect the pregnancy or baby. Food type, handling and preparation all matter; these four questions help you find the relevant guidance without treating every food the same.
Is it fresh, or fridge-aged?
Is it fresh?Listeria is unusual in that it keeps growing at fridge temperature. So a chilled, ready-to-eat food gets riskier the longer it sits — an opened pack of ham, last night’s leftovers, a bag of cut fruit. Time is the part you can control.
Chill promptly. Refrigerate perishable food within two hours, or one hour above 90°F (32°C). Most cooked leftovers keep for three to four days at 40°F (4°C) or below; reheat leftovers to 165°F (74°C). Follow any shorter package or local pregnancy guidance.
Check with a thermometer. Keep your refrigerator at 40°F (4°C) or below. A fridge thermometer helps you check the actual temperature.
Has it been cooked through?
Is it cooked?Use a food thermometer and the temperature for the food: poultry and reheated leftovers need 165°F (74°C), ground meat 160°F (71°C), and fish 145°F (63°C). Whole cuts of beef, pork and lamb need 145°F (63°C) plus a three-minute rest. Deli meat should be heated to 165°F or until steaming hot.
Eat hot food hot. If it should be steaming, let it steam.
Split the boards. Separate boards and hands between raw meat and anything you will eat uncooked.
Was it pasteurized and washed?
Is it pasteurized?Pasteurization is a controlled heat treatment that reduces harmful germs in milk and juice. Washing produce under running water removes dirt and reduces contamination; it is not the same as pasteurization and does not sterilize food. Check dairy labels, and wash produce yourself unless its label says it is ready to eat or prewashed.
Read one word. On the carton: pasteurized.
Rinse everything. Under running water, rubbing firm skins as you go. A knife through an unwashed melon drags whatever is on the rind into the flesh. No soap needed.
How much, and how often?
How much?Some guidance concerns infection; other advice concerns substances such as mercury, alcohol, vitamin A and caffeine. Amount, frequency and the specific substance matter. Cooking does not remove every risk, so check the relevant limit or avoidance advice.
Mercury
Mercury builds up as it moves up the ocean food chain, so the biggest, longest-lived predators carry the most. It affects the developing nervous system and your body is slow to clear it, which is why the advice is a weekly number of servings of low-mercury fish rather than no fish at all.
Alcohol
Alcohol reaches your baby at roughly the same concentration as in your own blood, and a developing liver has almost none of what it needs to break it down. No safe amount and no safe trimester have been found — which is why the advice is none at all rather than a limit, and why alcohol is the one thing here with no safer version.
Vitamin A
Too much preformed vitamin A can harm a developing baby. NHS guidance advises avoiding liver, liver products and supplements containing vitamin A during pregnancy. Beta-carotene in ordinary fruit and vegetables is different; ask your clinician about any supplement rather than treating all vitamin A sources alike.
Caffeine
Keep caffeine to no more than 200 mg a day during pregnancy. Coffee strength and serving size vary, so two mugs are not a reliable limit. Count tea, matcha, cola, energy drinks, chocolate and caffeine-containing medicines as well; check medicine use with your pharmacist or clinician.
If you have already eaten something on this list, it does not mean you or your baby will become ill. Contact your clinician if you feel unwell, develop fever or flu-like symptoms, or are worried about a recalled food. This page cannot assess an individual exposure.
The 8 foods to avoid during pregnancy — and the safer version of each
What the science says, in plain terms, and the version that keeps it on your plate. The chip on each card is the question to ask of it.
Deli meat & cold cuts
Sliced ham, turkey, salami and pâté sit chilled and ready to eat for days, which is exactly the window listeria needs. Pregnancy makes listeria roughly ten times more likely to take hold, and it is one of the few bacteria that reaches the baby.
Heat deli meat to 165°F (74°C) or until steaming hot throughout; toasting the bread alone is not enough. Shelf-stable canned fish is another option.
Unpasteurized dairy & soft cheese
Without pasteurizing, listeria, salmonella and E. coli can be in the milk from the start — the shared problem with raw milk, raw-milk yogurt and kefir, and unpasteurized juice or cider. Organic, local or very fresh makes no difference to it.
Soft cheeses are not all the same. CDC lists pasteurized feta, mozzarella, cottage cheese and cream cheese as safer choices. Queso fresco-type cheeses and deli-sliced cheeses need heating, even when pasteurized. For other soft cheeses, check the specific guidance and heat where recommended.
Choose pasteurized dairy and check the cheese type. Heat queso fresco-type or deli-sliced cheese to 165°F (74°C) or until steaming hot; pasteurization alone does not settle every cheese question.
Bagged salad & pre-cut fruit
For US readers, avoid unwashed produce and premade deli salads. Keep cut produce refrigerated and follow storage instructions and recalls. A prewashed salad label is not a guarantee against contamination, but bagged salad and all pre-cut fruit are not universal CDC avoidance categories.
Buy whole heads of lettuce, and wash and cut fruit yourself.
Raw & runny eggs
Salmonella can be on the shell and, occasionally, inside the egg; cooking until the white and yolk are firm kills it. The catch is how often raw egg turns up in things that don’t look like egg — homemade mayonnaise and aioli, hollandaise, Caesar dressing, mousse, meringue, cookie dough, cake batter.
Cook eggs until set. For shop-bought mayonnaise and dressings, check the label for pasteurized egg.
Sushi & raw seafood
Raw seafood may carry bacteria and parasites. Freezing can control some parasites but does not reliably eliminate harmful bacteria or mercury. During pregnancy, choose properly cooked fish and shellfish, and check the species for mercury guidance.
Cooked rolls — eel, tempura prawn, cooked crab — plus vegetable rolls.
Raw sprouts
Alfalfa, mung, clover and radish sprouts are grown warm and humid, which suits the seed and suits salmonella and E. coli just as well. The bacteria can be inside the seed itself, so rinsing the sprouts can’t reach them.
Cook them until steaming. For the same raw crunch, shredded cabbage or carrot does the job.
Tiramisu & raw-egg desserts
Tiramisu recipes vary: some contain raw egg and alcohol, while others use pasteurized eggs or a cooked mixture. Mousse, homemade ice cream and other chilled desserts also vary. Ask about the actual ingredients and preparation rather than assuming every recipe is the same.
Choose desserts made with pasteurized eggs and no alcohol, or a recipe that thoroughly cooks its egg mixture to the recommended temperature. Refrigerate promptly and account for any caffeine.
High-mercury fish
Fish provides useful nutrients during pregnancy. FDA/EPA advice is two to three 4-ounce servings weekly from the Best Choices list, OR one serving from Good Choices. Avoid the highest-mercury species. These are alternative weekly patterns, not allowances to add together.
Fish, sorted — one serving is 4 oz (113 g); choose one weekly pattern
Salmon · sardines · anchovies · trout · herring · mackerel (Atlantic) · cod · haddock · tilapia · pollock · prawns · scallops · canned light tuna
Albacore / white tuna · yellowfin tuna · halibut · Chilean sea bass · snapper · grouper · monkfish · mahi-mahi
Shark · swordfish · king mackerel · Gulf of Mexico tilefish · marlin · orange roughy · bigeye tuna
Ingredients often don’t appear under the name you are looking for, and there are exceptions — high-dose vitamin A, herbal blends, some supplements to name a few — sit outside the four questions altogether. The front of a pack tells you what kind of thing it is; the answer is in the ingredients panel, in small type and unfamiliar words.

Why does pregnancy food advice differ by country?
When two health bodies disagree, it is usually about their local food supply rather than the biology. Follow the guidance for the country whose food you are eating.
United States — ACOG, FDA & CDC
US guidance treats all raw fish as off the menu while pregnant, and asks for eggs cooked until firm unless they are pasteurized. Deli meat is safe once heated until steaming. The FDA/EPA advice on fish is two to three servings a week from the low-mercury list.
United Kingdom — NHS
NHS guidance advises avoiding raw fish, including sushi made with previously frozen raw fish. British Lion or Laid in Britain hen eggs can be eaten runny within their use-by date. Follow NHS advice for liver, supplements and soft mould-ripened cheeses.
Australia — NSW Food Authority
Australian guidance differs from the US. NSW Food Authority recommends avoiding chilled ready-to-eat foods such as cold deli meats, premade salads and soft-serve ice cream. Follow its food-by-food advice and local fish guidance rather than applying the US table unchanged.
Do these rules change by trimester?
Food-safety precautions apply throughout pregnancy. Avoid alcohol throughout pregnancy and follow the low-mercury fish guidance from the start. Do not use a trimester change as a reason to relax food handling or mercury precautions.
Does freezing kill listeria?
Freezing does not reliably kill listeria. Keep food safely stored and use the appropriate cooking or reheating temperature. Do not rely on freezing to make a recalled or otherwise unsafe food suitable to eat.
What about eating out — restaurants, buffets and salad bars?
Order things that arrive hot and freshly cooked, and treat anything that has been sitting out at room temperature the way you would a days-old leftover. Buffets, salad bars and self-serve counters are the weak point, not restaurants in general. Asking for a dish well done, or without the raw-egg dressing, is a normal thing to ask.
Is soft-serve ice cream a problem?
Soft-serve machines hold a milk mixture at a cool temperature for long stretches, so anything living inside a poorly cleaned machine has time to grow — which is why Australian guidance singles it out. Scooped ice cream from a sealed tub, made with pasteurized milk and eggs, doesn’t have the same problem.
Do the same rules apply while breastfeeding?
Breastfeeding has its own food and drink guidance; do not automatically carry every pregnancy restriction forward. Continue ordinary food hygiene and low-mercury fish choices. Ask your clinician about alcohol, caffeine, medicines and any individual concerns.
