Recently introduced to U.S. Congress, the Federal and State Food Safety Information Sharing Act aims to grant the U.S. Food and Drug Administration (FDA) the authority to share crucial food safety information with state and local regulatory agencies to improve foodborne illness outbreak response.

Ice cream has historically been associated with human cases of infection by various foodborne pathogens. Pathogen introduction into ice cream can occur at various points throughout the production process for a range of reasons, which can be addressed through proper food safety controls. 

With a focus on fresh-cut produce in the U.S./North America, this article explores critical questions related to the improvement and modernization of the microbial outbreak investigation process.

The U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA’s FSIS) recently published a summary of the six foodborne illness outbreak investigations involving FSIS-regulated products that took place during Fiscal Year (FY) 2023.

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.
