The U.S. Food and Drug Administration (FDA) has revealed preliminary findings from a multi-year environmental study of a specific growing region in the Southwest U.S., which sought to better understand the ecology of human pathogens in the environment.
Forward processing of leafy greens crops does not significantly increase the food safety risk posed by Escherichia coli, suggests a recent study led by a USDA Agricultural Research Service (USDA-ARS) scientist and funded by the Center for Produce Safety.
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.
A recent review has established pathogen-specific foodborne illness burden estimates for leafy greens in the U.S. by combining three outbreak-based attribution models with illness incidence and economic cost models.
A recent study has identified factors that determine the susceptibility of different leafy greens to foodborne Escherichia coli, including storage temperatures, leaf roughness, and natural wax coating. The researchers also found that the juices of kale and collard leaves have a natural antimicrobial effect.
As part of the agency’s Leafy Greens STEC Action Plan, the U.S. Food and Drug Administration (FDA) has published a report detailing the results of targeted inspections and microbiological testing of leafy greens grown in Salinas Valley, California during the region’s 2022 harvest season.
The U.S. Food and Drug Administration (FDA) has updated its Leafy Green STEC Action Plan (LGAP), which outlines the agency’s efforts to reduce foodborne illness outbreaks linked to leafy greens that were caused by Shiga toxin-producing Escherichia coli (STEC).
The Arizona and California Leafy Greens Marketing Association (LGMA) recently made available a new food safety tool to help growers and shippers assess risk in the crop production environment.
The U.S. Centers for Disease Control and Prevention (CDC) has identified a reoccurring, emerging, and persistent (REP) strain of Escherichia coli O157:H7—REPEXH02—that has been implicated in significant foodborne illness outbreaks linked to leafy greens from 2016–2019.
Research on plant defense responses against pathogens, specifically E. coli O157:H7 and Salmonella Typhimurium, holds insights to preventing foodborne illnesses and improving food safety practices.
