US Listeria outbreak associated with Tyson chicken products declared over

 

  

In July, the US Centers for Disease Control and Prevention (CDC) and other public health and regulatory officials in several US states, and the United States Department of Agriculture's Food Safety and Inspection Service (USDA-FSIS) began collecting different types of data to investigate a multi-state outbreak of Listeria monocytogenes infections.

 

Epidemiologic, laboratory and traceback data showed that frozen, fully cooked chicken products supplied by Tyson Foods Inc. had made people sick.

 

As of September 10, the CDC is declaring this outbreak is over.

 

Three people infected with the outbreak strain of Listeria monocytogenes were reported from two states, Delaware and Texas. Illnesses started on dates ranging from April 6, 2021, to June 5, 2021.

 

State and local public health officials interviewed people about the foods they ate in the month before they got sick. All three people were in a long-term care facility or hospital when they got sick. These facilities served many food items, including meals made with precooked chicken.

 

Whole genome sequencing (WGS) showed that bacteria from sick people’s samples were identical. This suggests that people in this outbreak got sick from the same food.

 

Frozen, fully cooked chicken products supplied by Tyson Foods Inc., were recalled.

 

Additional products made with Tyson Foods Inc. chicken were also recalled.

 

Products include chicken strips, pulled chicken, diced chicken, chicken wing sections, fully cooked pizza with chicken, chicken salad sandwiches, chicken wraps and salads with chicken.
