Pasta meals from Trader Joe's and Walmart may be linked to a deadly listeria outbreaktoggle caption USDA Food Safety and Inspection ServicePublic health authorities are urging people to throw away certain pre-cooked pasta meals sold at two popular retailers over concerns that they could be contaminated with listeria and connected to a worsening nationwide outbreak. Sponsor MessageThat outbreak made headlines in June, when listeria concerns prompted recalls of several brands of ready-to-eat chicken fettuccine Alfredo meals — made by FreshRealm, Inc. and sold at Kroger and Walmart — and triggered an investigation. Last week, its pasta samples came back positive for listeria. "It is also the same strain of Listeria that is linked to causing illnesses in this outbreak," the FDA says. The chicken pasta meals sold at Trader Joe's, for example, have use-by dates of Sept. 20, Sept. 24 and Sept. 27 on their front labels.
