USA: Salmonella outbreak linked to eggs

29 August, 2025

Federal health authorities are investigating a multistate outbreak of Salmonella Enteritidis infections traced to eggs distributed by Country Eggs, LLC, leading to a nationwide product recall.
As of August 27, the Centers for Disease Control and Prevention (CDC) confirmed 95 cases across 14 states. Eighteen patients required hospitalization, though no fatalities have been reported. Illnesses occurred between January 7 and July 26, 2025.
Epidemiological investigations indicate eggs as the likely source. Whole genome sequencing performed through the CDC’s PulseNet network confirmed that patient isolates were genetically related, suggesting a common food source. Notably, isolates from 94 patients exhibited resistance to nalidixic acid and reduced susceptibility to ciprofloxacin, two standard treatments for Salmonella, raising concerns about management of severe infections. Traceback analysis conducted by the Food and Drug Administration (FDA) identified Country Eggs, LLC as a common supplier in the outbreak. On August 27, the company initiated a voluntary recall of its egg products.
