Two Georgia residents are among those affected by a multistate outbreak of Listeria infections. The Centers for Disease Control and Prevention, public health officials in several states, and the U.S. Department of Agriculture’s Food Safety and Inspection Service are actively investigating the source.

Epidemiological data indicates that many of the 28 infected people, spread across 12 states, reported consuming meats sliced at deli counters. No evidence currently suggests that prepackaged deli meats are responsible.

Current Statistics and Demographics

From May 29, to July 5, samples from the infected individuals were collected. All 28 people with available information have been hospitalized.

There have been two deaths reported in Illinois and New Jersey. Of the 28 cases, one individual fell ill during pregnancy but recovered while still pregnant.

Notably, the outbreak likely extends beyond these reported cases, as some infected individuals may not seek medical care or get tested for Listeria. Furthermore, recent cases may still be pending confirmation due to the time required for reporting.

Data from the infected individuals shows:

Age range: 32 to 94 years, with a median age of 75.
Gender: 46% female, 54% male.

Race: 72% White, 23% African American/Black, 5% Asian.
Ethnicity: 96% non-Hispanic, 4% Hispanic.

Investigative Efforts

Health officials are gathering comprehensive data on the affected individuals, including their age, race, ethnicity, and dietary history. Interviews revealed that of the 18 people able to provide information, 16 (89%) reported consuming meats sliced at deli counters. Commonly cited meats include deli-sliced turkey, liverwurst, and ham, purchased from various supermarkets and grocery stores.

The CDC’s analysis comparing the diets of outbreak patients with those of non-outbreak Listeria cases indicates a higher likelihood of deli-sliced turkey and liverwurst consumption among the former group, suggesting a link to deli-sliced meats.

Laboratory Findings

Using the PulseNet system, investigators are employing whole genome sequencing to track the genetic fingerprint of the bacteria. This method has shown that the bacteria from all the patients are genetically similar, implying a common food source.

The USDA-FSIS is conducting traceback efforts to determine the suppliers of the deli meats consumed by the affected individuals.

Public Health Recommendations

The CDC urges those who are pregnant, aged 65 or older, or immunocompromised to seek medical advice if they exhibit symptoms of Listeria. To mitigate risks, it is recommended to avoid eating deli-sliced meats unless they are heated before consumption.

Authorities continue their efforts to pinpoint the exact source of the outbreak and prevent further infections.
