Most Caesar dressing you’ll find at the grocery store is safe during pregnancy. The concern comes from traditional recipes that use raw egg yolks, which carry a small risk of salmonella, a bacterial infection that can cause serious complications for a developing baby. If your Caesar dressing is made with pasteurized eggs or no eggs at all, you can enjoy it without worry.
Why Traditional Caesar Dressing Is a Concern
Classic Caesar dressing is made by whisking raw egg yolks with olive oil, anchovies, garlic, lemon juice, and Parmesan cheese. The raw egg is the problem. About 0.01% of all shell eggs in the U.S. contain Salmonella enteritidis bacteria, and because the dressing is never cooked, the bacteria survive if they’re present. That percentage sounds tiny, but it only takes one contaminated egg to cause an outbreak. In a well-documented 1991 case investigated by the CDC, 14 out of 15 people who got sick at a restaurant had eaten the Caesar salad. The dressing had been made that morning with 36 hand-cracked egg yolks and sat out in a chilled compartment for 8 to 12 hours.
For most healthy adults, a bout of salmonella means a few miserable days of diarrhea and cramping. During pregnancy, the stakes are higher. Salmonella infection has been linked to preterm birth, miscarriage, and inflammation of the membranes surrounding the baby. Research in animal models shows that even a low dose of the bacteria during late pregnancy can reduce fetal weight by altering how the placenta functions. Severe vomiting and diarrhea also raise the risk of dehydration, which can trigger contractions.
Store-Bought Dressing Is Generally Safe
Commercial Caesar dressings sold in bottles at the supermarket are made very differently from the restaurant original. Most use pasteurized eggs or egg products, which have been heat-treated to kill bacteria. Many don’t contain eggs at all, relying on commercial mayonnaise, soybean oil, or other emulsifiers for creaminess. The acidity from added vinegar or citric acid, combined with preservatives like sodium benzoate and potassium sorbate, further prevents bacterial growth. These dressings are shelf-stable before opening precisely because they’re engineered to be inhospitable to pathogens.
To confirm, check the ingredient list. If it lists “pasteurized eggs” or “pasteurized egg yolks,” it’s safe. If eggs aren’t listed at all, even better. Brands like Ken’s, Cardini’s, and most store-brand versions fall into this category.
What About Restaurants?
Restaurants are where you need to be more cautious. Higher-end restaurants and farm-to-table spots are more likely to make dressing from scratch with raw egg yolks. Chain restaurants, on the other hand, typically use pre-made dressings from commercial suppliers.
Before ordering a Caesar salad, ask your server whether the dressing is made in-house or comes from a bottle, and whether it contains raw eggs. If the staff isn’t sure, skip it or ask for the dressing on the side so you can check the packaging yourself. This isn’t an unusual request, and most restaurants will answer without hesitation.
The Other Ingredients Are Fine
Raw eggs get all the attention, but you might also wonder about anchovies and Parmesan, the other signature Caesar ingredients. Both are safe during pregnancy. Anchovies are a low-mercury fish, listed by the Mayo Clinic alongside other seafood that’s safe for pregnant women. The tiny amount blended into a salad dressing poses no mercury risk whatsoever.
Parmesan is a hard, aged cheese made from pasteurized milk, and the CDC lists it as a “safer choice” for pregnant women. Hard cheeses are inhospitable to Listeria, another bacteria that can be dangerous during pregnancy, because of their low moisture content and long aging process. So the cheese shavings on your Caesar salad are not a concern.
Making Caesar Dressing at Home
If you love Caesar salad and want to eat it regularly throughout pregnancy, making your own dressing gives you complete control. The simplest swap is using pasteurized eggs, which are sold at most grocery stores (look for the “pasteurized” label on the carton). These eggs have been gently heat-treated in the shell, so they’re safe to use raw while still giving you that traditional richness.
You can also skip eggs entirely. A base of plain Greek yogurt produces a creamy, tangy dressing that mimics the texture of the original. Blend it with a squeeze of lemon juice, a minced garlic clove, a spoonful of Dijon mustard, a few mashed anchovy fillets (or a dash of Worcestershire sauce), olive oil, and grated Parmesan. Full-fat yogurt gives the closest result, but low-fat works too. For a dairy-free version, substitute dairy-free yogurt and leave out the cheese.
Commercial mayonnaise is another safe base, since it’s made with pasteurized eggs and vinegar. Thinning mayo with lemon juice and adding the classic Caesar seasonings creates a dressing that’s rich and entirely pregnancy-safe.
Quick Reference: Safe vs. Risky Caesar Dressing
- Safe: Bottled store-bought dressing (pasteurized eggs, preservatives, acidified)
- Safe: Homemade with pasteurized eggs, yogurt, or commercial mayo
- Safe: Chain restaurant dressing from a commercial supplier
- Ask first: Any restaurant that makes dressing from scratch
- Avoid: Homemade dressing using raw, unpasteurized shell eggs
The bottom line is straightforward: the only version of Caesar dressing to avoid during pregnancy is one made with raw, unpasteurized eggs. Every other version, whether from a bottle, a careful home kitchen, or a restaurant that uses commercial dressing, is perfectly fine to enjoy.
