We’ve done extensive work on this topic dating back to 2006 (search barfblog.com), but new tools, like whole genome sequencing, mean additional outbreaks have been identified. A summary paper of recent outbreaks has just been published. Abstract below:
Frozen raw breaded chicken products (FRBCP) have been identified as a risk factor for Salmonella infection in Canada. In 2017, Canada implemented whole genome sequencing (WGS) for clinical and non-clinical Salmonella isolates, which increased understanding of the relatedness of Salmonella isolates, resulting in an increased number of Salmonella outbreak investigations. A total of 18 outbreaks and 584 laboratory-confirmed cases have been associated with FRBCP or chicken since 2017. The introduction of WGS provided the evidence needed to support a new requirement to control the risk of Salmonella in FRBCP produced for retail sale.

so on the label (right). Illnesses are also linked to chopped liver made from this product at retail stores. The outbreak strain of Salmonella Heidelberg was isolated by the New York State Department of Agriculture and Market from samples of broiled chicken livers from the establishment, and chopped chicken livers produced at retail from these livers. These products would have been repackaged and will not bear the original packaging information.
