Evidence for foodborne transmission of human listeriosis has increased recently, although proof of its occurrence requires: (a) a link between cases of disease and the consumption of a certain food; Listeriosis - annual epidemiological report for 2015. Human transmission mainly occurs via ingestion of contaminated foods and spe-cifically affects pregnant women, newborns, elderly individuals and immunosuppressed individuals.
