Vulto Creamery Listeria Cheese Outbreak
Case Count: Connecticut (1), Florida (1), New York (5) and Vermont (1)
CDC collaborated with public health and regulatory officials in several states and the U.S. Food and Drug Administration (FDA) to investigate a multistate outbreak of Listeria monocytogenes infections (listeriosis). Listeria causes a serious, life-threatening illness.
Listeria specimens from ill people were collected from September 1, 2016 to March 13, 2017. Ill people ranged in age from less than one year to 89 years, with a median age of 52 years. Five of eight ill people were female. All eight (100%) ill people were hospitalized, including two people from Connecticut and Vermont who died. One of the illnesses was reported in a newborn.
Epidemiologic and laboratory evidence indicated that soft raw milk cheese made by Vulto Creamery of Walton, New York, was the likely source of this outbreak.
State and local health departments interviewed ill people or their family members about the foods they ate or other exposures in the month before their illness started. Based on those interviews, eight (100%) of eight people ate a soft cheese. The ill resident of Florida reported traveling to New York state and eating soft cheese there before becoming ill. Available information indicated that cheese made by Vulto Creamery was for sale at stores where at least seven of the ill people bought cheese before getting sick.
The Connecticut Department of Public Health collected leftover cheeses from the home of the deceased person in Connecticut. The outbreak strain of Listeria was identified in a leftover cheese that the family identified as Ouleout cheese from Vulto Creamery.
The New York Division of Milk Control and Dairy Services collected three intact wheels of Ouleout cheese from Vulto Creamery. The outbreak strain of Listeria was identified in samples taken from the three wheels of cheese. On March 7, 2017, Vulto Creamery recalled all lots of Ouleout, Miranda, Heinennellie, and Willowemoc soft wash-rind raw milk cheeses. On March 10, the company expanded the recall to include four other cheeses: Andes, Blue Blais, Hamden, and Walton Umber. The raw milk cheeses were distributed nationwide, with most sold in stores in the northeastern and Mid-Atlantic states; California; Chicago; Portland, Oregon; and Washington, D.C.
