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.

A 2021 multinational foodborne illness outbreak investigation involving imported melons contaminated by Salmonella Braenderup exemplifies effective collaboration across countries, rapid information sharing, and harmonized data collection, and the lessons learned could form the basis of standard practices in multinational outbreak investigations.

As of November 24, 2023, a fatal foodborne outbreak of salmonellosis linked to cantaloupes has caused 99 illnesses across 32 states in the U.S., and 63 illnesses across five provinces in Canada. A total of three patients have died. A recall has been issued.

The European Food Safety Authority (EFSA) has put out an alert regarding an international outbreak of Salmonella Enteritidis in chicken, involving 335 cases across 14 European countries plus the UK, as well as the U.S.

Salmonella spp. have long been associated with low-moisture foods such as nuts and nut-derived products, with varying prevalence observed in tree nuts, including cashews, at retail. Virtually all cashews are imported to the U.S. Some nuts, including cashews, are imported as a "raw" product (i.e., one that has not been subjected to a process to adequately reduce pathogens, such as a kill step). Salmonella contamination of such products has resulted in several notable outbreaks in the U.S. in the past ten years, including those in which cashew-containing products have been implicated as a vehicle. This article presents a brief overview of outbreak investigations of Salmonella infections linked to the consumption of cashews and cashew-containing food products. It also presents challenges encountered, lessons learned, and relevant regulatory requirements for importers and manufacturers of cashews and cashew-containing products.

The European Food Safety Authority (EFSA) and the European Center for Disease Prevention and Control (ECDC) recently published a summary of a joint investigation of a multi-country foodborne illness outbreak of Salmonella Seftenberg that was possibly linked to cherry-like tomatoes.

The U.S. Centers for Disease Control and Prevention (CDC) recently published a new webpage with information about a persistent, multidrug-resistant strain of Salmonella Infantis known as REPJFX01, which has been the cause of many illnesses and outbreaks.

In a new video and infographic, the U.S. Food and Drug Administration (FDA) has provided an overview of the traceback process used during foodborne illness outbreaks to investigate a food’s path through the supply chain.

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.

U.S. Representative Rosa DeLauro (CT-03) has reintroduced the Expanded Food Safety Investigation Act, which would give the U.S. Food and Drug Administration (FDA) the authority to investigate corporate livestock feedlots and confinement operations implicated in foodborne illness outbreaks.
