Deadly Listeria Outbreak Exposes Hidden Risks in Ready-to-Eat Foods
A multi-state Listeria monocytogenes The outbreak has transformed a basic meal into a public health emergency. Six people died and 25 were hospitalized after eating contaminated prepackaged pasta sold at major grocery stores like Trader Joe’s, Walmart and Kroger.
The U.S. Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) are working together to trace the source of the outbreak, first announced in June 2025.
Investigators linked the infections to ready-to-eat pasta from supplier Nate’s Fine Foods, including precooked fettuccine, linguine and bow-tie pasta. These products can be refrigerated or frozen and are designed to be lightly cooked in the microwave or oven. A list of contaminated products is available on the USDA Food Safety and Inspection Service website.

For what Listeria Do you like ready-to-eat foods?
Bacteria L. monocytogenes can cause listeriosis, a potentially fatal infection. Listeria is the third leading cause of foodborne illness death in the United States, responsible for approximately 172 deaths each year. It is a persistent microbe that can thrive even in cold environments, surviving refrigeration and sometimes growing in packaged foods over time.
When it comes to food, Listeria Often spreads in processing facilities where bacteria can be difficult to eliminate, even in the cleanest circumstances. Listeria can enter a food processing facility through multiple routes, including through contaminated food during the harvesting process. It can also be spread within the establishment through food processing, preparation, packaging and transportation.
Something as modest as incoming air can contain traces of L. monocytogenes and be enough to trigger an epidemic.
Symptoms of Listeria Infection
If you have contracted ListeriaSymptoms usually appear within two weeks of eating contaminated food, but can appear as early as the day of consumption or up to 10 weeks later. For most healthy adults, the illness may go away with rest and fluids, but the infection can be devastating for pregnant women, newborns, the elderly, and people with weakened immune systems.
According to the FDA press release, “mild symptoms may include fever, muscle aches, nausea, fatigue, vomiting, and diarrhea. If the more severe form of listeriosis develops, symptoms may include headache, neck stiffness, confusion, loss of balance, and seizures.”
Most people who encounter L. monocytogenes will contract a non-life-threatening intestinal disease. In these cases, the infection will likely present with flu-like symptoms and clear up without medical intervention. However, the invasive strain of L. monocytogeneswhere the bacteria spreads beyond the intestine, is fatal: nearly one in six people who contract invasive listeriosis will die.
What can you do to protect yourself Listeria?
The good news is that Listeria infection is preventable. Awareness and good refrigeration habits can make all the difference. In the face of the current outbreak, consumers are encouraged to check their refrigerators and freezers for recalled products.
To protect against Listeria At home, keep your refrigerator at 40 degrees Fahrenheit or colder and your freezer at 0 degrees Fahrenheit. Wash produce, cook food thoroughly, and promptly throw away anything that looks suspicious or expired.
If you ate recalled pasta and experience fever, fatigue, or muscle aches, the CDC recommends contacting a healthcare professional immediately. However, if you don’t have any symptoms, testing or treatment is probably not necessary.
