map-09-17-2015On September 16, 2015, Karoun Dairies, Inc. voluntarily recalled and ceased production of certain cheeses that the company distributes due to possible contamination with Listeria. The recall includes several brands and types of cheeses that were distributed to retail outlets in the United States. Products were sold under the following brands: Karoun, Arz, Gopi, Queso Del Valle, Central Valley Creamery, and Yanni. Products are vacuum packed, in jars or in pails. Weights vary from 5 ounces to 30 pounds. A full list of cheeses is available on the Advice to Consumers, Restaurants, and Retailers page.

The CDC has reported that twenty-four people infected with one of the closely related Listeria strains have been reported from nine states since August 8, 2010. The number of ill people reported from each state is as follows: California (14), Colorado (1), Illinois (1), Massachusetts (2), Michigan (1), New York (2), Ohio (1), Tennessee (1), and Washington (1).

Dates of Listeria specimen collection range from August 8, 2010 to August 24, 2015. The cluster was first identified in August 2015 after investigators saw an increase in one of the five rare PFGE  fingerprints reported to PulseNet. WGS found that the four other PFGE fingerprints were closely related genetically to the first PFGE fingerprint. Illnesses associated with those PFGE fingerprints were added to the investigation, including illnesses that occurred over 5 years ago. Additional illnesses are under investigation.

Ill people range in age from less than 1 year to 92, and the median age is 77. Seventy-five percent of ill people are female. Twenty-one (91%) of 23 ill people for whom information is available reported being hospitalized. Five of the illnesses were pregnancy-related, and one illness resulted in a fetal loss. One death was reported from Ohio.
