It was not immediately clear how many deaths were caused by the listeria outbreak. The CDC said listeriosis contributed to "at least one" of two deaths in New York and Nebraska but did not elaborate. A third deceased person in Minnesota was infected with listeriosis linked to the cheese but that is not thought to be the primary cause of death, a spokesman for the Minnesota Department of Health said.
Three people from Maryland reported becoming ill from the strain of listeria linked to the ricotta. One person each from California, Colorado, District of Columbia, Nebraska, New Jersey, New Mexico, Ohio, Pennsylvania and Virginia also reported an illness. Two of the illnesses were in newborn babies, the CDC said.
