The CORE Outbreak Investigation Table is a list of outbreak and adverse event investigations primarily being managed by FDA’s CORE Response Teams. The investigations are in a variety of stages, meaning that some outbreaks have limited information, and others may be near completion. The table will be updated weekly.
This week’s updates are:
- A new outbreak of E. coli O157:H7 (ref #1269) linked to a not yet identified product has been added to the table. FDA has initiated traceback.
- For the outbreak of E. coli O121:H19 (ref #1273) linked to a not yet identified product, the case count was adjusted from 33 to 37 cases.
- For the outbreak of E. coli O157:H7 (ref #1270) linked to onions, FDA updated the outbreak advisory.
- For the outbreak of Salmonella Thompson (ref #1262) linked to a not yet identified product, the outbreak has ended.
- For the outbreak of E. coli O157:H7 (ref #1249) linked to a not yet identified product, the outbreak has ended.
- For the outbreak of Listeria monocytogenes (ref #1247), FDA’s investigation has closed.
- For the outbreak of Cyclospora cayetanensis (ref #1245), FDA’s investigation has closed. CDC, FDA, and state and local partners conducted epidemiologic and traceback investigations and identified shrimp salad, made with fresh produce ingredients, as the source of illnesses in this outbreak. FDA collected and analyzed product and ingredient samples as part of the investigation, but all samples were reported as negative for Cyclospora. Due to the lack of additional supporting evidence, investigators were unable to determine a specific ingredient as the source of contamination while the outbreak was considered ongoing. All product is past shelf life and is no longer on the market. There is no ongoing risk to public health.
- For the outbreak of Cyclospora cayetanensis (ref #1237), FDA’s investigation has closed and the case count has adjusted to 49. CDC, FDA, and state and local partners conducted epidemiologic and traceback investigations and identified imported parsley as the source of illnesses in this outbreak. FDA initiated on-site inspections and collected and analyzed product and ingredient samples as part of the investigation, but all samples were reported as negative for Cyclospora. Due to the lack of additional supporting evidence, investigators were unable to determine a specific source of contamination while the outbreak was considered ongoing. All product is past shelf life and is no longer on the market. There is no ongoing risk to public health.
- For the outbreak of Salmonella Typhimurium (ref #1234), FDA’s investigation has closed. CDC, FDA, and state and local partners conducted epidemiologic and traceback investigations and identified jalapeno pepper as the source of illnesses in this outbreak. FDA collected and analyzed product samples as part of the investigation, but all samples were reported as negative for Salmonella. Additionally, once investigators had enough information to confirm jalapenos as the source of this outbreak, the products were past their shelf life and no longer available for sale. This outbreak is over and there is no risk to consumers.
