Listeria monocytogenes is an organism that “can cause serious and sometimes fatal infections” in young children, the elderly or those with weakened immune systems, the company said in a news release. It can also lead to serious pregnancy complications. Healthy people may suffer short-term symptoms including high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea.
The affected product was packaged in clear plastic clamshell containers with the Kirkland Signature brand label with a pack date of Sept. 18, 2025, and a sell-by date of Sept. 22, 2025.
It was sold at the deli sections of Costco Warehouse stores on Sept. 18 in 33 states: Alabama, Alaska, Colorado, Connecticut, Delaware, Florida, Georgia, Idaho, Indiana, Louisiana, Maine, Maryland, Massachusetts, Minnesota, Mississippi, Missouri, Montana, Nebraska, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Ohio, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Utah, Virginia, Washington and Wisconsin.
Consumers are advised not to eat the product, to dispose of it and to visit their local Costcos for full refunds.
Listeria infection is the third leading cause of death from foodborne illness in the United States, with an estimated 1,600 people infected every year, according to the Centers for Disease Control and Prevention.
In May, at least 10 people were hospitalized in California and Nevada in a listeria outbreak involving ready-to-eat foods produced by Fresh & Ready Foods LLC of San Fernando, California, which issued a voluntary recall at the time. More than 80 products were included in the recall, ranging from snack boxes to sandwiches and pastas.
In February, food service company Lyons Magnus recalled a range of nutritional milkshakes after they were linked to 12 deaths and dozens of serious infections.
