FDA

What’s New

  • A new outbreak of E. coli O157:H7 (reference #1121) in a not yet identified product has been added to the table and traceback has been initiated.
  • For the outbreak of Salmonella Litchfield in seafood, (reference #1105), FDA issued an Outbreak Advisory on 10/19/2022.
  • Based on CDC’s epidemiological investigation of two large multistate outbreaks of Cyclospora cayetanensis (reference #1080 and #1084), ill people reported eating a variety of leafy greens before becoming sick. For both investigations, CDC, FDA, and state and local partners conducted epidemiologic and traceback investigations and collected and analyzed product and environmental samples. All samples collected were reported as negative for Cyclospora. Due to the lack of additional detail in the epidemiological data and the absence of supporting evidence collected from traceback and sample collection, FDA could not identify a specific product as the source of either outbreak.
  • For the outbreak of Salmonella Senftenberg (reference #1087) in a not identified product, one additional case was reported, the outbreak has ended, and FDA’s investigation has closed.
  • For the adverse illness event series in frozen food (reference #1076), the outbreak has ended, and the FDA investigation has closed.
