Three people have died and more than a dozen others were hospitalized following an outbreak of listeria that has been linked to premade chicken fettuccine alfredo meals sold nationwide at Kroger and Walmart, federal health officials said Wednesday.

The strain of listeria bacteria tied to the outbreak was found in a sample of chicken fettucine alfredo during a routine inspection in March.

FreshRealm is recalling certain chicken fettuccine alfredo products that may contain an outbreak strain of listeria monocytogenes contamination.
