At least three people have died due to a listeria outbreak linked to chicken fettuccine alfredo meals distributed to Walmart and Kroger stores. The Centers for Disease Control and Prevention and public health officials are conducting an investigation into an outbreak linked to the meals sold at retail locations nationwide.

The company that made the meals issued a nationwide recall as the Centers for Disease Control and Prevention said they were linked to 17 listeria cases across 13 states.

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