The U.S. Food and Drug Administration (FDA) and the U.S. Centers for Disease Control and Prevention (CDC) have closed an investigation into a multi-state Salmonella outbreak linked to eggs that caused 134 infections, 38 hospitalizations, and one death.

Illnesses were confirmed in ten states: Arizona, California, Colorado, Kansas, Kentucky, Nebraska, New Jersey, Nevada, Utah, and Washington. The last onset of illness was reported on June 6, 2025.

Cage-free brown eggs and certified organic eggs supplied by August Egg Company of Hilmar, California were determined as the vehicle of illness.

The outbreak and a recall of implicated products was first announced by FDA on June 5, 2025. The recalled eggs are now past expiration and should no longer be available for sale at retail stores.

As part of its investigation, FDA conducted an inspection and environmental sampling at cage-free laying houses used by August Egg Company. Whole genome sequencing (WGS) analysis matched the three Salmonella-positive environmental samples from the investigation to the outbreak strain of Salmonella.

FDA is working with both August Egg Company and the laying houses on corrective and preventive actions.
