A multistate outbreak of Listeria monocytogenes linked to Lyons ReadyCare and Sysco Imperial Frozen Supplemental Shakes has resulted in at least 38 illnesses and 11 deaths across 21 states, primarily affecting individuals from long-term care facilities. The FDA was notified of the outbreak on November 25, 2024, and has since identified the source through traceback investigations, which revealed that the implicated shakes were distributed to foodservice customers such as hospitals and care facilities. Of the reported cases, 37 individuals have been hospitalized, with 34 of them residing in long-term care settings prior to illness. This ongoing outbreak includes cases dating back to 2018, with 20 new cases reported in 2024 and 2025. Certain products have been voluntarily recalled, although detailed recall information has not yet been posted on the FDA's website. Symptoms of Listeria infection can be severe, necessitating medical attention for those who may have consumed the affected products.
