The total case count in the ongoing Listeria outbreak linked to imported Italian ricotta cheese has expanded from 18 to 20 and one more victim has died, announced the Centers for Disease Control and Prevention in an update Friday. The two new illnesses were reported in California. One of these two victims died, bringing the total number of victim deaths from three to four. Last week, Food Safety News reported on two cases in California that had not yet been counted in CDC’s investigation update – a pregnant mother who contracted a Listeria infection and her son who was born prematurely September 19 and died October 4. CDC and the California Department of Public Health have yet to confirm whether the mother, Joanna Valentine, and her son Felix were the newly counted two cases and death linked to the outbreak, but it’s likely that they are, since the outbreak strain of Listeria was isolated from both the baby and the placenta. Also, CDC’s last update reported that two illnesses linked to the outbreak were diagnosed in newborns, and that number has now been raised to three, indicating that the newly reported infant case is likely Ms. Valentine’s son. Out of the 20 people in 12 states and Washington, D.C. who’ve now been infected with the outbreak strain of Listeria monocytogenes, 19 have been hospitalized, reports CDC. One stillbirth has also been tied to the outbreak. The 11 victims who were not fetal or newborn range in age from 30 to 87 years old, with a median age of 77, according to CDC’s update. The contaminated cheese causing this outbreak is imported from Italy by Forever Cheese of Long Island City, New York and sold under the Marte brand as Ricotta Salata Frescolina.
