Sumary of Factors Potentially Contributing to the Contamination of Peaches Implicated in the Summer 2020 Outbreak of Salmonella Enteritidis:
- Food and Drug Administration (FDA) and multiple state and federal partners investigated an outbreak of Salmonella Enteritidis infections linked to peaches packed or supplied by a large grower/producer..
- Based on the historical outbreak data, this multistate outbreak appears to represent a novel commodity/pathogen pair..
- The epidemiological and traceback investigation identified the large grower/producer packinghouses, cooling facilities and/or orchards as a potential source of the peaches and helped prioritize investigational activities..
- The investigation did not result in finding the outbreak strain (via whole genome sequencing (WGS)) in investigation samples, however, numerous Salmonella isolates were found in samples collected from the peach orchards..
- Multiple Salmonella isolates from product (peach) and peach tree leaf sampling activities conducted during this investigation genetically resembled historical chicken and cattle isolates not associated with this outbreak or any known foodborne illnesses..
- The large grower/producer cooperated with FDA throughout the investigation and is continuing to engage with FDA on the agency findings and recommendations….
