CDC announced that the outbreak due Listeria monocytogenes of fully cooked chicken products supplied by Tyson Foods is over

In July 2021, CDC, public health, and regulatory officials in several states and the USDA-FSIS began investigating a multistate outbreak of Listeria monocytogenes infections. Epidemiologic, laboratory, and traceback data showed that frozen, fully cooked chicken products supplied by Tyson Foods Inc. were the cause. On July 3, 2021, Tyson Foods Inc recalled approximately 8,955,296 pounds of ready-to-eat chicken products. Additional products made with Tyson Foods Inc. chicken were recalled on July 8 and July 13, 2021. As of September 10, 2021, this outbreak is over. Three people infected with the outbreak strain of Listeria monocytogenes were reported from two states. All three people were in a long-term care facility or hospital when they got sick. WGS showed that bacteria from sick people’s samples were identical, suggesting that people in this outbreak got sick from the same food. USDA-FSIS found the outbreak strain of Listeria in two samples of fully cooked chicken products during routine product testing. USDA-FSIS and partners collected food purchase records from the long-term care facility and hospital to determine the source of the fully cooked chicken products served. USDA-FSIS found that the Tyson facility in Dexter, Missouri, produced one of the products that tested positive for the outbreak strain. The product was supplied to another firm. From this firm, a positive sample was collected.  The product was distributed to the long-term care facility and the hospital. @ https://www.cdc.gov/listeria/outbreaks/precooked-chicken-07-21/details.html
