2023 Multistate Outbreak of Listeriosis Linked to Soft Serve Ice Cream
In August 2023, CDC, state, and local public health officials investigated an outbreak of Listeria monocytogenes associated with Real Kosher Soft Serve Ice Cream. Two cases - one in New York and one in Pennsylvania were identified. Both cases were hospitalized. No one died.
The Pennsylvania Department of Agriculture found the outbreak strain of Listeria in an unopened "Soft Serve on the Go" vanilla chocolate ice cream cup that the sick person had in their freezer. The New York State Department of Agriculture and Markets found the outbreak strain of Listeria in five "Soft Serve On the Go" ice cream cups that were collected from Real Kosher Ice Cream's manufacturing location.
The New York City Department of Health and Mental Hygiene found the outbreak strain of Listeria in an "Ice Cream House" mini dessert cigar novelty ice cream product and several environmental samples taken from The Ice Cream House.
"Ice Cream House" products and Soft Serve On the Go" ice cream cups are made at the same facility.
The investigation was closed on October 26, 2023.
