To help predict and mitigate the presence of Escherichia coli and other foodborne pathogens on lettuce, a new weather-based model has been developed by USDA-ARS researchers and collaborators.

Through sampling activities and whole genome sequencing (WGS) analysis, a recent research project funded by the Center for Produce Safety (CPS) revealed insights about the movement of L. monocytogenes across a processing facility, the persistence of the pathogen, and the efficacy of biocides and sanitation practices.
