Interpretive Summary: The persistence of foodborne pathogens (such as Escherichia coli, Listeria monocytogenes and Salmonella enterica) in agricultural soils compromises the safety of fresh produce. USDA scientists isolated 3 bacteria of the genus Paenibacillus that can inhibit these pathogens growth. To elucidate information regarding their ability to inhibit pathogens they sequenced their genomes and will perform future studies to identify genes involved in pathogen suppression in both the pre- and post-harvest periods.

Technical Abstract: Three Paenibacillus spp., designated SEL1, SEL2, and SEL3, were isolated from soil samples collected at lettuce farms in the Salinas Valley of California in fall 2020. Genomic sequencing of these isolates was performed using the PacBio Revio platform. All three genomes possess circular whole-genome sequences and lack detectable plasmids.
