The Ever-Present Risk of Salmonella in Raw Eggs
For many, the idea of a protein-packed raw egg is a health food staple, but the reality is that the risk of bacterial contamination from Salmonella is an enduring concern. Despite advancements in food production and safety measures, instances of contaminated eggs still occur. According to the CDC, Salmonella is one of the most common causes of foodborne illness, and eggs have frequently been identified as a source. The bacteria can be present inside an egg before the shell is even formed, and contamination can also happen from outside sources during handling.
Recent events, such as the egg recalls announced by the FDA in 2025 due to Salmonella contamination, serve as a critical reminder that this risk is not a thing of the past. These incidents demonstrate that even with strict monitoring, contaminated products can enter the market. For this reason, regulatory bodies like the USDA and FDA consistently advise against consuming raw or undercooked eggs unless they have been pasteurized.
The Role of Pasteurization in Egg Safety
Pasteurization is a heat-treatment process that significantly reduces the number of harmful bacteria in food products, like eggs, without cooking them. This process makes it safe to consume eggs in their raw form for preparations where the egg isn't cooked, such as homemade mayonnaise, Caesar salad dressing, or certain desserts. For consumers looking to mitigate the risk associated with raw eggs, especially raw yolks, pasteurized versions are the recommended choice.
Commonly pasteurized egg products include:
- In-shell eggs (clearly labeled on the carton)
- Liquid egg products (such as cartons of pre-cracked yolks or whites)
- Meringue powder
While finding pasteurized shell eggs might be less common than liquid products, their availability is increasing. When a recipe calls for raw egg and safety is a priority, switching to pasteurized eggs is a simple and effective solution.
Raw vs. Pasteurized Eggs: A Comparison
To better understand the trade-offs, here is a comparison of raw, unpasteurized eggs and pasteurized eggs.
| Feature | Raw (Unpasteurized) Eggs | Pasteurized Eggs |
|---|---|---|
| Salmonella Risk | Small but persistent risk of bacterial contamination from Salmonella inside or on the shell. | Risk of Salmonella is virtually eliminated by the heat-treatment process. |
| Recommended Use | Can be used if fully cooked until both the yolk and white are firm. Not recommended for raw dishes. | Recommended for recipes calling for raw or lightly cooked eggs, like dressings, sauces, and certain desserts. |
| Nutrient Absorption | Protein absorption may be lower compared to cooked eggs, and raw whites can hinder biotin absorption. | Comparable nutrient profile to raw eggs, with improved protein absorption due to denaturing of proteins. |
| Vulnerable Groups | Must be avoided by high-risk individuals, including the elderly, young children, pregnant women, and the immunocompromised. | Safe for all populations when used raw in recipes that require them. |
| Taste & Texture | Preferred by some for certain recipes, but the risk remains. | May exhibit slight textural changes, such as looser whites, but yolks perform similarly in recipes like hollandaise or dressings. |
Addressing the Bird Flu Concern
Alongside the perennial Salmonella risk, recent news has highlighted concerns about the H5N1 bird flu virus affecting poultry farms. While this is a serious issue for the poultry industry, experts agree that the risk of contracting bird flu from properly cooked eggs is extremely low. Pasteurization is also effective at killing the virus. Most significantly, chickens infected with the virus typically stop laying eggs, reducing the likelihood of infected eggs entering the marketplace. As with Salmonella, the key is to ensure eggs are thoroughly cooked to a safe internal temperature.
Proper Handling to Minimize Risk
For those who choose to continue using unpasteurized eggs in cooked dishes, proper handling is paramount to minimize risks, especially avoiding cross-contamination.
- Refrigerate Immediately: Always buy eggs from a refrigerated case and store them in the coldest part of your own refrigerator, not the door, upon returning home.
- Inspect Your Eggs: Before use, discard any eggs that are cracked or dirty.
- Wash Your Hands: Thoroughly wash your hands with soap and water after handling raw eggs.
- Prevent Cross-Contamination: Use separate utensils, cutting boards, and bowls for raw eggs and other foods. Sanitize all surfaces that come into contact with raw egg.
- Serve Promptly: Consume raw egg dishes immediately after preparation. Never leave them at room temperature for more than two hours.
Conclusion
In summary, while there is no definitive moment where raw eggs become 'safe,' the risks are consistently low for the general population, provided proper food safety practices are followed. However, the risk of Salmonella is an enduring reality, underscored by recent recalls in 2025. This risk is unacceptable for vulnerable individuals, who should always opt for cooked or pasteurized eggs. For everyone else, the safest, most risk-free option for dishes requiring raw egg yolks, is to use pasteurized eggs or egg products. Informed decision-making and adhering to established food safety guidelines are the best ways to protect your health and enjoy your food.

Key Takeaways
- Salmonella risk is ongoing: Recent recalls in 2025 confirm that a risk of Salmonella contamination from unpasteurized eggs persists.
- Pasteurized eggs are the safest option: Use pasteurized eggs or egg products for all uncooked or lightly cooked recipes, especially for vulnerable groups.
- Vulnerable populations should avoid raw eggs: Elderly people, young children, pregnant individuals, and the immunocompromised are at high risk of severe illness from Salmonella and should not consume raw eggs.
- Cooking kills bacteria: For unpasteurized eggs, cooking until both the yolk and white are firm is the most effective way to eliminate harmful bacteria.
- Proper handling is crucial: Always refrigerate eggs, avoid cracked or dirty shells, and prevent cross-contamination by washing hands and surfaces after handling.
