Are Eggs Safe During Pregnancy?

The Verdict: Yes, With One Firm Rule

Eggs are a genuinely good food during pregnancy, but you need to cook them until both the white and the yolk are firm. The single non-negotiable is no runny yolks and no soft-set whites. Once an egg is fully cooked, it is a safe, nutrient-dense, affordable source of high-quality protein, choline, and other nutrients your body and baby use heavily right now. The caution here is entirely about how the egg is prepared, not about whether to eat eggs at all.

Why Runny Yolks Are the Problem

The concern is salmonella, a bacterium that can be present inside or on the shell of raw and undercooked eggs. In a typical healthy adult, salmonella usually causes a few miserable days of fever, cramping, vomiting, and diarrhea. In pregnancy your immune system is naturally dialed down, so a foodborne infection can hit harder, last longer, and lead to dehydration that may require treatment. Severe vomiting and diarrhea can also trigger uterine contractions, which is why the bar for prevention is higher than usual.

Heat is what kills salmonella. A runny yolk or a glossy, undercooked white simply has not reached a high enough internal temperature to make the egg reliably safe. That is the whole mechanism, and it is the reason this page lands on caution rather than a clean green light.

Exactly How to Eat Eggs Safely

Cook eggs until the white is completely set and the yolk has thickened and is no longer liquid. Scrambled eggs should look dry rather than wet and glossy. Fried eggs are safest cooked on both sides (over-hard) or covered so the top sets; skip sunny-side-up. Hard-boiled and well-cooked omelets and frittatas are easy wins. For casseroles, quiches, and egg bakes, cook until the center is firm and a knife comes out clean.

There is no strict daily limit on cooked eggs for most pregnant people, and an egg or two a day fits comfortably into a balanced diet. If you have high cholesterol or another medical condition, follow whatever guidance your provider has already given you about eggs. One smart shortcut: pasteurized eggs (in the shell or as cartoned liquid egg) have been gently heat-treated to kill salmonella, so they are the safer choice anytime a recipe calls for lightly cooked or raw egg.

The Hidden Raw-Egg Foods to Watch

The bigger real-world risk often is not your breakfast plate but foods that quietly contain raw or barely-cooked egg. Homemade Caesar dressing, fresh mayonnaise, hollandaise and bearnaise sauce, raw cookie dough and cake batter, homemade ice cream, tiramisu, mousse, eggnog, and meringue or royal icing can all hide uncooked egg. When eating out, ask how a sauce or dressing is made, and at home use pasteurized eggs for any recipe where the egg will not be fully cooked. Commercial, store-bought versions of mayonnaise and dressings are typically made with pasteurized egg and are fine.

Trimester Notes and a Word on Nutrition

The cooking rule does not change by trimester; firm yolks are the standard from your first positive test through delivery. Early on, when nausea makes plain proteins appealing, well-cooked eggs are an easy, gentle option. Eggs are also one of the best dietary sources of choline, a nutrient that supports your baby's developing brain and is often under-supplied even by prenatal vitamins, so fully cooked eggs are a useful thing to keep on the menu throughout pregnancy.

Breastfeeding Is More Relaxed

Once your baby has arrived and you are breastfeeding, the salmonella math changes. A foodborne illness in you does not pass through breast milk to your baby, so the pregnancy-specific caution eases. That said, food poisoning is still unpleasant and can leave you dehydrated and depleted at a time when you need your energy, so cooking eggs well remains a sensible habit even if it is no longer a hard rule.

When to Call Your Provider

If you ate an undercooked egg and feel fine, you almost certainly do not need to do anything. Call your provider if, after any suspect food, you develop a fever, persistent vomiting or diarrhea, signs of dehydration such as dizziness or very dark urine, or diarrhea that lasts more than a day or two. And contact them promptly for any pregnancy red flags alongside illness, including belly cramping, contractions, or changes in your baby's movements. When in doubt, a quick call is always reasonable.

The Bottom Line

Eat eggs freely during pregnancy, but cook them until the white and yolk are firm, and use pasteurized eggs for anything that stays raw or runny.
