In an after-action review of a 2022 Escherichia coli O157:H7 outbreak linked to ground beef, the U.S. Food and Drug Administration’s Food Safety and Inspection Service (USDA’s FSIS) highlights the importance of improving outreach to food retail stores about best food safety practices for beef that will be ground.

Researchers are exploring the potential of protective bacterial cultures to mitigate the growth of foodborne pathogens that have developed antimicrobial resistance.

The U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA’s FSIS) has announced upcoming changes and expansions to its beef sampling and testing programs for Escherichia coli and Salmonella. 

A Center for Produce Safety-funded study is working to characterize the physiological changes that occur in Shiga toxin-producing Escherichia coli O157:H7 (STEC) bacteria that is present on romaine lettuce during postharvest cooling and refrigerated transport to processors, which could affect the pathogen’s virulence and detectability characteristics. The end goal of the research is to develop an easily accessible online tool for industry that identifies practices to mitigate the risks of STEC transmission via romaine lettuce.

The Food and Agriculture Organization of the United Nations (FAO) recently published two reports—one on control measures for Shiga toxin-producing Escherichia coli (STEC) in meat and dairy products, and another reviewing Listeria monocytogenes attribution, characterization, and monitoring in ready-to-eat (RTE) foods.

A study has demonstrated the economic impacts of foodborne illness outbreaks on supply chains by observing the damages caused by the 2018 Escherichia coli outbreak that was linked to romaine lettuce grown in California.

The U.S. Food and Drug Administration (FDA) has announced that it will conduct targeted sampling of leafy greens as part of the Leafy Greens STEC Action Plan (LGAP). The agency also provided updates on the progress of LGAP and a summary report of a 2021 sampling assignment.

The U.S. Centers for Disease Control and Prevention (CDC) has summarized its investigations of possible multistate outbreaks caused by Salmonella, Shiga toxin-producing Escherichia coli (STEC), and Listeria monocytogenes in 2017–2020. 

Due to concerns about Escherichia coli O157:H7 contamination, The Canadian Food Inspection Agency (CIFA) has implemented temporary Safe Food for Canadians (SFC) license conditions for romaine lettuce imports from the U.S., specifically California’s Salinas Valley.

The U.S. Department of Agriculture’s Agricultural Research Service (USDA’s ARS) recently published a Research Brief that highlights two recent food safety studies related to Shiga-toxin-producing Escherichia coli O157:H7.
