Can Green-Shelled Eggs Cause Food Poisoning?
Yes—but only in the same way that white, cream, or brown eggs can.
The main recognized food-safety concern associated with shell eggs is Salmonella. According to the U.S. Food and Drug Administration, even fresh eggs with clean, uncracked shells may sometimes contain Salmonella bacteria.
If contaminated eggs are eaten raw or undercooked, they may cause diarrhea, fever, abdominal cramps, vomiting, and other symptoms of foodborne illness. Symptoms often begin within 12 to 72 hours and commonly last four to seven days, although serious cases may require hospital treatment.
The outside color of an egg does not tell consumers whether Salmonella is present. A spotless green egg is not automatically safer than a white egg, while a white egg is not automatically safer than a green one.
Food safety depends much more on farm hygiene, refrigeration, shell condition, preparation, cooking temperature, and the prevention of cross-contamination.
This is the most important point for consumers: do not fear the natural green pigment, but do not let the attractive color create a false sense of safety either.
Who Faces the Greatest Risk?
Most healthy people recover from Salmonella infection without specific treatment, but the illness can become severe.
The FDA identifies young children, older adults, pregnant women, and people with weakened immune systems as groups at higher risk of serious complications. This includes people undergoing certain cancer treatments, transplant recipients, and individuals with conditions that weaken their ability to fight infection.
People in these groups should be especially careful about dishes containing raw or lightly cooked eggs. Examples include homemade mayonnaise, Caesar dressing, eggnog, mousse, tiramisu, uncooked cake batter, homemade ice cream, soft scrambled eggs, and eggs with runny whites.
Pasteurized shell eggs or pasteurized egg products are safer choices when a recipe will not cook the egg thoroughly. Pasteurization is designed to destroy Salmonella without fully cooking the egg or significantly changing how it can be used in recipes.
