Safety Status: Avoid Entirely
Traditional, raw-egg hollandaise sauce should be strictly avoided during pregnancy.
According to guidelines from the U.S. Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC), raw egg products are high-risk sources of Salmonella enteritidis. Hollandaise is a classic French emulsion made by whisking raw egg yolks with melted butter and acid (lemon juice or vinegar).
During preparation, the egg yolks are gently warmed over a double boiler, but they are not cooked to the temperature required to pasteurize them. Salmonella can survive this gentle heating. If the eggs are contaminated, eating the sauce can lead to severe food poisoning, resulting in vomiting, diarrhea, high fever, and maternal dehydration, which can trigger uterine irritability or preterm labor.
Furthermore, restaurants often hold hollandaise sauce in warm water baths for several hours. This holding temperature (110°F to 120°F / 43°C to 49°C) is inside the food safety “danger zone,” allowing any bacteria present to multiply rapidly.
Safe Alternatives & Cooking Rules
You can safely enjoy eggs benedict and hollandaise sauce with these precautions:
- Commercially Prepared Hollandaise: Purchase jarred, canned, or powdered hollandaise sauce from the supermarket. These products are commercially pasteurized and shelf-stable, making them safe for pregnant individuals.
- Use Pasteurized Eggs: Make hollandaise at home using commercially pasteurized liquid eggs or in-shell pasteurized eggs. Pasteurized eggs have been heat-treated to destroy Salmonella while remaining liquid, making them safe for emulsions.
- Verify at Restaurants: When dining out, ask if the hollandaise is made from pasteurized paste or liquid eggs. If the staff cannot confirm, choose a different sauce.
Kitchen Hygiene and Handling
If you prepare pasteurized hollandaise at home:
- Do Not Let Sit: Serve the sauce immediately after preparation.
- Discard Leftovers: Do not store and reheat homemade hollandaise. Discard any leftover sauce that has sat at room temperature for more than 2 hours.
- Wash Hands: Wash your hands and cooking utensils with hot soapy water after handling raw eggshells.
Safe Alternatives
Pasteurized commercially prepared hollandaise sauce, or homemade hollandaise made with pasteurized liquid eggs.
OB-GYN Clinical Tip
When dining out at brunch restaurants, always ask the staff if their hollandaise sauce is made from pasteurized eggs. Traditional restaurant-made hollandaise is often unpasteurized and kept warm (not hot enough to kill bacteria), presenting a high risk.
