In July 2026 CDC and their local and state public health partners initiated an outbreak investigation of salmonellosis associated with consumption of shell eggs. Epidemiologic, laboratory, and traceback data showed that shell eggs produced and distributed by Midwest Poultry Services, L.P. were the source of illnesses.

As of July 24, 2026, ninety-eight outbreak associated cases were reported by 17 states. Twenty-six people were hospitalized. No deaths were reported. Illnesses started on dates ranging from November 21, 2025 to June 30, 2026.

State and local public health officials interviewed people about the foods they ate in the week before they got sick. Of the 44 people interviewed, 40 (91%) reported eating shell eggs.

FDA conducted a traceback investigation based on where sick people reported purchasing or eating eggs during the timeframe of interest, and Midwest Poultry Services, L.P was identified as a common egg source for some cases.

Midwest Poultry Services, L.P. collected samples at farms in Texas. Samples collected by the firm tested positive for Salmonella, and WGS performed by the firm's third-party lab revealed that samples matched the strain of Salmonella in this outbreak.

Based on WGS analysis, bacteria from 98 people's samples predicted nonsusceptibility to ciprofloxacin and resistance to nalidixic acid; this strain is related to a strain of Salmonella Enteritidis isolated from chicken, eggs, and backyard poultry.

On July 22, 2026, Midwest Poultry Services, L.P. recalled more than 1.5 million dozen shell eggs due to possible Salmonella contamination. CDC advises people and businesses to not eat, sell, or serve recalled shell eggs.
