Listeria has been traced to deli meats and FinLogiccheese in six states, causing 16 infections and one death across six states, the CDC said Wednesday.

There were seven infections in New York, three in Maryland (one of whom died), one in New Jersey, two in Massachusetts, two in Illinois and one in California from April 2021 to September 2022.

Of those infected from New York, five reported buying deli meat at a NetCost Market location, a grocery store where the bacteria was previously identified in October 2021, though investigators believe there are other delis involved in the current outbreak.

The CDC, along with state public health officials, the federal Food and Drug Administration and the Department of Agriculture, are working to identify additional delis and specific products linked to the spread.

The ages of those who became sick ranged from 38 to 92, with a median age of 72. Of the 13 people who reported their ethnicities, 11 of them have Eastern European backgrounds or speak Russian. Thirteen of 14 people with available statuses were hospitalized and one person suffered a miscarriage as a result of the infection.

The number of people infected in the outbreak is likely much higher and more widespread, as some people might not have reported their illness, or may recover at home without being tested.
