Update of the deadly Yu Shang Listeria outbreak

The deadly outbreak of Listeria monocytogenes due to Yu Shang RTE poultry products has ended. The outbreak caused 24 illnesses in nine states: California (14), Georgia (1), Illinois (2), Michigan (1), Nevada (1), New Jersey (1), New York (1), Oregon (1), and Tennessee (2). The illnesses occurred over three years. Samples from sick people were collected from October 24, 2021, to January 25, 2025. Twenty-two of the patients were hospitalized. Eight illnesses were related to pregnancy, according to the CDC. A California mother and her twins were sick, and both infants died. Listeria was found in samples tested from the mother and one of the twins but not from the other infant. For this reason, only the mother and one twin are included as confirmed cases in this outbreak. A Tennessee mother and her infant were sick, and her infant died. WGS was performed on the Listeria cultured from the patients. Results showed the fingerprints closely resemble one another, suggesting that the patients were exposed to the same source of contamination. Tests on Yu Shang products were positive for Listeria, and WGS showed it matched the outbreak strain. @ https://www.pritzkerlaw.com/personal-injury/2025/deadly-yu-shang-listeria-outbreak/
