- CDC investigated this outbreak in 2019 and 2020 and reopened the investigation in November 2021 when four new illnesses were reported since the end of August.
- In October 2021, as a part of routine retail sampling, the Georgia Department of Agriculture collected a product sample of prepackaged salad mix from a grocery store for testing. The sample tested positive for Listeria monocytogenes. In response to the sample results, Dole initiated a recall of packaged garden salads in October 2021. These products are now past their “Best if Used By” dates.
- The positive sample was later sent for whole genome sequencing (WGS) analysis; and in December 2021, WGS analysis was completed. The results show that the Listeria monocytogenes in the product sample was a match to the outbreak strain. FDA is conducting an inspection at the facility that produced the product that tested positive for Listeria monocytogenes.
- The Michigan Department of Agriculture and Rural Development also recently initiated retail sampling of Dole products in their state as part of this investigation. One product containing lettuce from the Dole facility in Yuma, AZ, tested positive for Listeria monocytogenes. WGS analysis showed that the Listeria monocytogenes in the product sample is also a match to the outbreak strain.
- In response to the sample analyses and the ongoing outbreak investigation, Dole has agreed to voluntarily suspend operations at both the Bessemer City, NC, facility and Yuma, AZ, facility and has voluntarily recalled all products and brands from those facilities. Those products have production lot codes beginning with either the letter “N” or “Y” in the upper right-hand corner of the package and Best if Used By dates from November 30, 2021 to January 8, 2022.
