The Centers for Disease Control and Prevention (CDC) posted a food safety alert on February 24 regarding a multistate outbreak of Listeria infections linked to frozen supplement shakes that were distributed to food service operators and long-term care facilities.
Key Points:
- On February 22, 2025, Lyons Magnus LLC recalled 4 oz. Lyons ReadyCare and Sysco Imperial Frozen Supplemental Shakes due to the potential for the products to be contaminated with Listeria monocytogenes.
- Thirty-eight people from 21 states have been infected with this outbreak strain of Listeria. Thirty-seven people have been hospitalized, and 12 people have died.
- While cases date back to 2018, over half of the people affected by this outbreak got sick in either 2024 or 2025. It is common for Listeria outbreaks to last several years because it is an incredibly hardy germ that can survive on surfaces for long periods of time.
- CDC has investigated this strain several times but never had enough information to identify a food source, beyond something being served in long-term care facilities. Environmental testing and whole genome sequencing helped solve the outbreak this year.
- Lyons ReadyCare and Sysco have recalled all supplement shakes under their brands and within shelf life, and questions about the recall should be directed to FDA.
- The ages of those affected range from 43-101 years, with older adults over the age of 65 years being the most affected.
- These shakes were distributed nationwide to institutional settings like long-term care facilities and given most commonly to those on medically necessary soft diets.
- These products are not available to the general public and are only available to institutional settings like long-term care facilities.
