The US Department of Agriculture’s Food Safety and Inspection Service is issuing a public health alert for ready-to-eat meals containing a Food and Drug Administration-regulated pre-cooked pasta that may be contaminated with Listeria monocytogenes. FSIS expects more updates as this investigation continues.

The following product is subject to the public health alert: 12-ounce clear plastic tray packages labeled “MARKETSIDE LINGUINE WITH BEEF MEATBALLS & MARINARA SAUCE” with “best if used by” dates SEP 22, 2025; SEP 24, 2025; SEP 25, 2025; SEP 29, 2025; SEP 30, 2025; and OCT 01, 2025.

The product bears establishment number “EST. 50784” or "EST. 47718" inside the USDA mark of inspection. This item was shipped to Walmart locations nationwide.

The producing company collected samples of the FDA-regulated, pre-cooked pasta used as an ingredient in these products as part of the ongoing investigation related to the Listeria outbreak linked to chicken fettuccine alfredo meals. The test confirmed that the linguine pasta was positive for Listeria monocytogenes, and further testing is ongoing to determine if the Listeria monocytogenes is genetically related to the specific outbreak strain. FSIS previously issued a recall notice linked to the Listeria outbreak in June 2025 and continues to coordinate with FDA, the Centers for Disease Control and Prevention, and state public health partners.

Consumption of food contaminated with Listeria monocytogenes can cause listeriosis, a serious infection that primarily affects older adults, persons with weakened immune systems, and pregnant women and their newborns. Less commonly, persons outside these risk groups are affected.

Listeriosis can cause fever, muscle aches, headache, stiff neck, confusion, loss of balance and convulsions sometimes preceded by diarrhea or other gastrointestinal symptoms. An invasive infection spreads beyond the gastrointestinal tract. In pregnant women, the infection can cause miscarriages, stillbirths, premature delivery or life-threatening infection of the newborn. In addition, serious and sometimes fatal infections can occur in older adults and persons with weakened immune systems. Listeriosis is treated with antibiotics. Persons in the higher-risk categories who experience flu-like symptoms within two months after eating contaminated food should seek medical care and tell the health care provider about eating the contaminated food.

FSIS is concerned that some product may be in consumers’ refrigerators or freezers. Consumers who have purchased these products are urged not to consume them. These products should be thrown away or returned to the place of purchase.
