Foodborne Diseases Active Surveillance Network (FoodNet) data allow examination of incidence trends and differences.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We analyze sporadic invasive listeriosis cases reported to FoodNet from 2008 to 2023. Incidence rates and rate ratios are calculated overall and by studied period, pregnancy status, age, sex, race, and ethnicity.

No significant temporal trend in any studied subpopulation is observed. Pregnant women have a 64-fold (95% CI, 47\u201387) higher risk when compared to non-pregnant women of reproductive age. Incidence rate in the non-pregnant population rises with age, and Hispanic, non-Hispanic Asian, and non-Hispanic Black populations have higher rates than non-Hispanic White populations. An increased overall incidence rate would have been expected because of demographic shifts; instead, the observed stable incidence rate suggests approximately 16% lower exposure to Listeria monocytogenes in 2023 compared with 2008.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Stable listeriosis incidence rates despite demographic shifts suggest reduced population exposure to L monocytogenes.
