FDA Recall Notice: Ready Care & Sysco Imperial Shakes by Lyons Magnus Due to Listeria Contamination

Recall , July 14, 2025

On February 21, 2025, Lyons Magnus initiated a voluntary nationwide recall of its Ready Care and Sysco Imperial frozen nutritional shakes after the discovery of Listeria monocytogenes, a potentially deadly foodborne pathogen. This contamination resulted in 38 hospitalizations and 12 fatalities across 21 U.S. states. [1]

Root Cause Analysis

  • Poor hygiene in production areas: Contaminated surfaces, especially in cold-chain zones.
  • Missed validation of kill-step for Listeria: Lack of microbial lethality verification during pasteurization or sterilization.
  • Lack of HACCP implementation and audit: Missing hazard analysis and control measures, with no proper documentation.
  • No environmental swabbing or sanitation monitoring: No routine pathogen monitoring in equipment or air vents. [2]

FDA Recall Lyons Magnus Ready Care & Sysco Imperial Shakes (Listeria Risk) blog

Affected Lots: Complete list of batches to be published by Lyons Magnus and FDA; representative samples include:

Lot RC1124 – Best By: May 2025

Lot SI2402 – Best By: June 2025

Lot RC2201 – Best By: April 2025

Lot SI2410 – Best By: July 2025 [3]

Issue Identified

Frozen shakes contained Listeria monocytogenes, a bacterium with serious health consequences specifically for pregnant women, older adults, immunocompromised, and those with medical conditions.

Reported symptoms:

  • Extreme high fever
  • Muscle pain
  • Gastrointestinal upset
  • Confusion or neurological symptoms in severe cases

The outbreak caused 12 deaths and 38 hospitalizations, which resulted in urgent recall of the affected products.  [4]

Regulatory Body Issues

  • The FDA and CDC cooperatively launched an investigation into the outbreak and product traceback
  • The plant was deemed noncompliant with Good Manufacturing Practices (GMP)
  • Lyons Magnus was instructed to cease operations until sanitation improvements and protocol adjustments [1]

The recall was graded as a Class I Recall highest level of severity because of life-threatening risk

Consumer Guidance by Manufacturer

Lyons Magnus has advised all parties, including consumers, to:

  • Discontinue use of Ready Care and Sysco Imperial frozen nutritional shakes immediately from impacted lots
  • Dispose of the product safely or return it to the place of purchase
  • Health institutions should quarantine and dispose of stock from affected batches
  • Anyone who develops symptoms after use should receive medical attention immediately
  • Report adverse events to FDA MedWatch
  • Lyons Magnus is adopting new microbial surveillance procedures and strengthened sanitation controls [5]

FRL Commentary

This recall serves as a harsh reminder that prevention of pathogens in clinical nutrition items needs to be more than standard food safety practices.

FRL advises manufacturers of medical foods and supplements:

  • Conduct validated environmental swab testing in refrigerated areas
  • Implement predictive microbiology model for Listeria and other pathogen
  • Perform third-party GMP audits on a quarterly basis
  • Implement lot-level traceability and create cold-chain risk assessments

Priority Action

Description

·        Environmental Swabbing Program

·       Routinely test production zones and air ducts for Listeria

·       HACCP with Pathogen Kill-Step Validation

·       Validate thermal or sterilization procedures

·        Cold-Chain Risk Analysis

·       Ensure temperature integrity and microbial risk modeling

·       GMP Training & Third-Party Audits

·       Train staff, enforce SOPs, and audit facilities quarterly

Meticulous food safety engineering and sustained compliance monitoring are what protect the health of at-risk populations.

Finalizing Comments

The Ready Care and Sysco Imperial shake recall is a high-impact illustration of how hygienic failure and microbial control breakdown can result in disastrous public health repercussions. Microbial safety must be treated by clinical nutrition manufacturers as a mission-critical concern particularly for cold-chain and high-risk food segments.
