Using whole genome sequencing (WGS), U.S. federal and state public health officials recently solved a multistate foodborne illness outbreak investigation that has been ongoing since 2014, with the most recent illnesses being reported in December 2023.

The World Health Organization (WHO) recently published a three-part guide describing how whole genome sequencing (WGS) can be used as a tool to strengthen foodborne illness surveillance and response.

The U.S. Department of Agriculture (USDA) has announced the appointment of 21 new members and nine returning members to the National Advisory Committee on Microbiological Criteria for Foods (NACMCF). A virtual public meeting will be held in November to welcome the committee members and introduce a new charge on the genomic characterization of pathogens.

The establishment of a comprehensive surveillance program that harnesses the benefits of whole genome sequencing (WGS) requires a coordinated approach involving multiple stakeholders at multiple levels within the framework of One Health. EFSA is actively collaborating with the network of EU experts to foster cooperation and promote equitable data-sharing practices, and is also committed to ensuring a more balanced contribution from all European countries and providing effective support and resources when necessary.

A recent study aiming to investigate the usefulness of publicly available whole genome sequencing (WGS) data for Salmonella surveillance has provided an overview of antimicrobial resistance (AMR) among different serovars and defined the most common antibiotic resistance genes.

Using whole genome sequencing (WGS), a recent study led by Michigan State University (MSU) has demonstrated widespread antimicrobial resistance (AMR) among foodborne Campylobacter jejuni in the state, and the ability to trace the origins of specific strains.

A survey of non-typhoidal Salmonella (NTS) found on retail foods sold in the UK has shown the overall prevalence of Salmonella to be low, although there is great genetic diversity among the Salmonella that was present, which may hinder outbreak investigations and source attribution in the case of foodborne illness outbreaks. 

The Canadian Food Inspection Agency (CFIA) recently highlighted a new rapid tool called GeneSeekR that can confirm if Escherichia coli detected in food samples can cause illness in humans.

State and local health departments in Washington are investigating five cases of foodborne illness caused by Listeria monocytogenes in Western Washington, three of which have resulted in death. Whole genome sequencing (WGS) has indicated a common source of infection.

Expert scientists from nine African countries convened recently in Accra, Ghana to launch a new wave of diagnostic testing using DNA sequencing aimed at improving food safety and controlling antimicrobial resistance (AMR).
