Deadliest Listeria Outbreak in Over a Decade Linked to Recalled Frozen Nutrition Shakes
A Growing Outbreak with Severe Consequences
Federal and state health officials have announced a rapidly growing listeria outbreak linked to recalled frozen supplemental nutrition shakes, resulting in 38 confirmed infections and 12 fatalities across 21 states. The contaminated products were manufactured by Prairie Farms Dairy at a facility in Fort Wayne, Indiana. Swabs collected from the processing area of the plant tested positive for listeria, and the investigation is ongoing, according to the Food and Drug Administration (FDA). The affected states include Alabama, California, Colorado, Connecticut, Florida, Illinois, Indiana, Maryland, Michigan, Minnesota, Missouri, North Carolina, Nevada, New York, Ohio, Oklahoma, Pennsylvania, Tennessee, Texas, Washington, and West Virginia.
The Centers for Disease Control and Prevention (CDC) has reported that the outbreak includes illnesses dating back to 2018, with 20 cases occurring in 2023 and 2024 alone. Of the 38 individuals for whom detailed information is available, 37 have been hospitalized, highlighting the severity of the infections. Notably, the majority of those infected were residents of long-term care facilities or were hospitalized before falling ill, underscoring the vulnerability of these populations to listeria infections.
This outbreak has already surpassed the death toll of a 2024 listeria outbreak linked to Boar’s Head deli meats, which caused 10 deaths and 57 illnesses. It is now considered one of the deadliest listeria outbreaks in the U.S. since 2011, when contaminated cantaloupe caused widespread illness and fatalities.
Listeria Infections: Understanding the Risks
Listeria monocytogenes, the bacteria responsible for this outbreak, can cause severe and sometimes fatal infections, particularly in vulnerable populations such as the elderly, young children, and individuals with weakened immune systems. While healthy individuals may experience milder symptoms like fever, headache, nausea, and diarrhea, the infection can lead to more serious complications, including miscarriages and stillbirths in pregnant women.
The CDC and FDA are urging consumers, especially those in high-risk groups, to take immediate action to avoid exposure to contaminated products. The outbreak has raised concerns about food safety, particularly in institutional settings like nursing homes, where the recalled shakes were primarily distributed.
Recalled Products and Consumer Guidance
The recalled products include Lyons ReadyCare and Sysco Imperial Frozen Supplemental Shakes, which were supplied by Prairie Farms Dairy and distributed by Lyons Magnus, a Fresno, California-based food manufacturer. These shakes were sold in four-ounce servings and came in flavors such as vanilla, chocolate, strawberry, and strawberry banana. The recalled products have best-by dates ranging from February 21, 2025, to February 21, 2026.
Lyons Magnus issued the recall on February 22, 2024, and has advised consumers to "quarantine" any recalled products they may have. The company has provided additional information on its website and encourages consumers to contact them directly at frozenshakerecall@lyonsmagnus.com for further assistance.
Protecting Yourself and Your Loved Ones from Foodborne Illness
To prevent listeria infections and other foodborne illnesses, it’s essential to follow safe food-handling practices. Here are some tips to help you stay safe:
- Check for Recalls: Regularly check your pantry, fridge, and freezer for recalled items. You can sign up for recall alerts from the FDA or other food safety organizations to stay informed.
- Follow Storage Instructions: Always store perishable items at proper temperatures, and ensure frozen foods are kept at 0°F (-18°C) or below.
- Clean and Sanitize: Wash your hands thoroughly before and after handling food. Clean all surfaces, utensils, and containers that come into contact with food.
- Cook and Reheat Safely: Cook meals to the recommended internal temperature, and reheat leftovers to at least 165°F (74°C) to kill harmful bacteria.
- Avoid High-Risk Foods: Pregnant women, older adults, and individuals with weakened immune systems should avoid high-risk foods like soft cheeses, raw sprouts, and deli meats unless they are heated to an appropriate temperature.
By taking these precautions, you can significantly reduce the risk of foodborne illness for yourself and your loved ones.
The Importance of Vigilance in Food Safety
This outbreak serves as a stark reminder of the importance of food safety and the need for vigilance, particularly when it comes to vulnerable populations. Institutions and caregivers must prioritize the safety of the food they serve, especially in settings like nursing homes, where residents may already be at heightened risk for severe infections.
While the investigation into the Prairie Farms Dairy facility continues, consumers are urged to remain cautious and take proactive steps to protect themselves from listeria and other foodborne pathogens. By staying informed, following food safety guidelines, and holding food manufacturers accountable, we can work together to prevent future outbreaks and safeguard public health.
For now, the focus remains on supporting the families affected by this tragic outbreak and ensuring that all necessary measures are taken to prevent similar incidents in the future. Stay informed, stay vigilant, and prioritize your health and safety.
