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 outbreak, which includes at least 17 people in 13 states, began last July, officials said. At least 16 people have been hospitalized.

Ready-to-eat chicken fettuccine Alfredo meals sold at Walmart and Kroger have been recalled after a listeria outbreak that has led to 17 illnesses including three deaths and one fetal loss.
