Outbreak Background – June 6, 2025
Federal health officials, working with state and local authorities, are actively investigating a multistate Salmonella outbreak connected to eggs.
Combined epidemiological evidence, laboratory testing, and traceback data have established that eggs from August Egg Company are possibly contaminated with Salmonella and may be making people sick.

State and local authorities are actively interviewing those infected about the foods they ate prior to becoming ill.
Twenty-seven (27) of the 30 interviewed to date reported eating eggs.
Health officials have identified two illness sub-clusters at two different restaurants. According to the CDC, “An illness sub-cluster is a group of unrelated sick people who all ate at the same location or event, such as a restaurant.” Eggs were served at both sub-cluster restaurants.
Laboratory and Traceback Findings – June 6, 2025
Health officials are utilizing the PulseNet surveillance system to identify cases potentially connected to this outbreak. The CDC operates PulseNet as a nationwide database containing genetic profiles of bacteria responsible for foodborne diseases. Scientists analyze bacterial samples using whole genome sequencing (WGS) to create detailed DNA profiles.
Genetic analysis revealed that bacterial samples from those infected share close genetic similarities, indicating exposure to a common contamination source.
The FDA inspected August Egg Company’s production plant and gathered product samples for laboratory analysis. Testing revealed that several samples contained Salmonella bacteria. Whole genome sequencing analysis demonstrated that the Salmonella strains found in these samples have a close genetic match to the Salmonella strains isolated from individuals who became ill.
Whole genome sequencing revealed that bacterial samples from 79 patients showed expected resistance to nalidixic acid and reduced susceptibility to ciprofloxacin. This particular strain matches a Salmonella Enteritidis variant previously found in chickens, eggs, and backyard poultry. One patient’s sample indicated additional resistance to ampicillin and streptomycin. While most Salmonella infections resolve without antibiotic treatment, cases requiring medication in this outbreak might not respond to standard antibiotics and could need alternative treatment options. Additional details can be found through the National Antimicrobial Resistance Monitoring System (NARMS) website.
Affected individuals purchased various egg brands from different retailers. The FDA traced back the supply chain by investigating where sick people shopped and dined during the relevant time period, which led them to identify August Egg Company as a shared egg supplier.
Some patients from Kentucky, New Jersey, and Washington had visited California and Nevada prior to developing their illness.
Consumer and Commercial Action – June 6, 2025
Anyone in possession of the recalled eggs, are strongly advised to not eat, serve, sell, donate, or further distribute them.
Health Risks
Salmonella is a bacterium that can cause severe gastrointestinal illness in humans. Symptoms typically include diarrhea, fever, and stomach cramps, appearing six hours to six days after exposure to the bacteria. While most people recover without specific treatment, the infection can be severe, especially for young children, the elderly, and individuals with weakened immune systems.
