A total of 134 people infected with the outbreak strain of Salmonella Enteritidis were reported from 10 states. Six sick people reported traveling to California or Nevada in the week before they got sick. Illnesses started on dates ranging from February 24, 2025, to June 6, 2025. Of the 112 people with information available, 38 were hospitalized. One death was reported from California. 

The true number of sick people in this outbreak was likely much higher than the number reported, and this outbreak may not have been limited to the states with known illnesses. This is because many people recover without medical care and are not tested for Salmonella.

FDA conducted an inspection at cage-free laying houses used by August Egg Company and collected samples for testing. Three samples tested positive forSalmonella Enteritidis. WGS showed that the Salmonella Enteritidis in the samples matched to Salmonella from sick people.

People reported buying many different brands of eggs from multiple stores. FDA conducted a traceback investigation based on where the ill people reported shopping or eating during the timeframe of interest. August Egg Company was identified as a common supplier of eggs. 

Ill people in Kentucky, New Jersey, and Washington reported traveling to California and Nevada before they got sick.
