Can you eat homemade mayonnaise while pregnant?
Check firstOnly with pasteurized eggs, otherwise skip it. Classic homemade mayonnaise and aioli are built on raw egg yolk, which carries a Salmonella risk, but mayonnaise made from pasteurized shell eggs or liquid pasteurized egg is fine.
Why
The emulsion is never cooked, so whatever is in the yolk stays in the jar. NHS guidance on foods to avoid singles out foods containing raw or partially cooked egg, including homemade mayonnaise, and FoodSafety.gov tells pregnant women to avoid raw egg dishes such as homemade mayonnaise, Caesar dressing and hollandaise because of Salmonella. Salmonella in pregnancy means fever, vomiting and dehydration at a time when you are already more vulnerable, and severe illness can affect the pregnancy. The fix is simple rather than restrictive: make it with pasteurized eggs in the shell or a carton of pasteurized liquid egg, and the raw-egg risk goes away. Store-bought jarred mayonnaise is made with pasteurized egg and is safe as is. Lemon juice and vinegar in the recipe do not reliably kill Salmonella, so acidity is not a substitute.
Safer alternatives
- Jarred mayonnaise such as Hellmann's or Kewpie
- Homemade mayo whipped from pasteurized shell eggs
- Aioli made with Greek yogurt, garlic and lemon
- Mashed avocado or hummus as a sandwich spread

Frequently asked questions
Is store-bought mayonnaise safe in pregnancy?
Yes. Commercial mayonnaise is made with pasteurized egg, so there is no raw-egg risk. Keep the jar refrigerated once opened and use it by the date on the label.
What about aioli or Caesar dressing at a restaurant?
Ask whether it is made in house with raw egg. Restaurant aioli and traditional Caesar dressing often are, which puts them in the avoid column. Many kitchens use pasteurized liquid egg or a jarred base, and staff can usually tell you.
I ate homemade mayonnaise before I knew. Should I worry?
The odds are strongly in your favor, since most eggs are not contaminated. Watch for fever, stomach cramps, vomiting or diarrhea over the next few days and call your provider if any of those appear. One exposure with no symptoms needs no action.
