A listeria food poisoning outbreak that has killed three people and led to one pregnancy loss is linked to newly recalled heat-and-eat chicken fettucine alfredo products sold at Kroger and Walmart stores, federal health officials said late Tuesday.

The outbreak, which includes at least 17 people in 13 states, began last July, officials said. At least 16 people have been hospitalized.

FreshRealm, a large food producer with sites in California, Georgia and Indiana, is recalling products made before June 17. The recall includes these products, which were sold in the refrigerated sections of retail stores:

    listerias is a problem if your immunocompromised, or pregnant, usually its milder in healthy people. the reason why its so virulent amongs susceptible, because it can zoom around infected cells, using thier cytoskeleton, this allows it to spread from cell to cell very quickly, while most other infections require the cells bursting, or the bacteria exiting the cell.

      I don’t really understand how “outbreak strains” are identified or tracked, but this if what the linked FDA paper in the article says:

      FSIS and public health partners are investigating an outbreak of Lm that currently includes 17 ill people in 13 states. As of June 17, 2025, there have been three reported deaths and one fetal loss associated with this outbreak. The outbreak strain of Lm was isolated from ill people on dates ranging from August 2024 – May 2025. The same outbreak strain was isolated from a routine chicken fettuccine alfredo sample collected by FSIS in a FreshRealm establishment in March 2025. The lot of chicken fettuccine alfredo represented by this sample was held during sampling, destroyed, and never entered commerce. The subsequent investigations at the establishment that produced this product, and into the product ingredients, have not identified the source of contamination. FSIS also used purchase records from two ill people to trace purchased chicken fettuccine alfredo products to FreshRealm establishments. An additional two ill people verbally described chicken fettuccine alfredo products they purchased. FSIS identified products produced by FreshRealm that matched the descriptions during follow-up at the retail stores where they shopped. This investigation is ongoing. FSIS is sharing what is currently known regarding products associated with the outbreak as the agency continues to work with public health partners to identify whether a specific ingredient in the chicken fettucine alfredo may be the source of this strain of Lm.
