The USDA has posted a list with labels of the chicken products included in the recall.

The USDA said the recall came after the agency was notified June 9 of two people sick with listeriosis. An agency investigation identified three listeriosis illnesses, including one death, between April 6 and June 5, the agency said. Two chicken samples collected during the investigation were found to contain bacteria closely related to the strains involved in those illnesses, the USDA said, and one of those chicken samples was collected at Tyson Foods.

Tyson said the recalled products were produced at its Dexter, Mo., plant between late December and mid-April, and were sold to restaurants and supermarkets across the U.S. and Puerto Rico.

The company said the recall was voluntary and that there was no conclusive evidence that the chicken products were contaminated at the time of shipment.

“We are taking this precautionary step out of an abundance of caution and in keeping with our commitment to safety,” said Scott Brooks, Tyson’s senior vice president of food safety.

Listeria is a potentially deadly bacteria. Generally it doesn’t cause illnesses in healthy people, but it can threaten older adults, pregnant women and newborns, as well as people with weakened immune systems.

The recall comes as Tyson’s chicken business, the nation’s largest in terms of pounds produced, has struggled to keep up with surging demand. The Arkansas-based company has been raising wages to keep its poultry plants staffed, while spending tens of millions of dollars to buy meat from rivals to meet its customers’ orders, executives said in May.
