There are >2,600 recognized serovars of Salmonella enterica. Many of these Salmonella serovars have a broad host range and can infect a wide variety of animals, including mammals, birds, reptiles, amphibians, and insects. In addition, Salmonella can grow in plants and can survive in protozoa, soil, and water. Hence, reducing human infections will require the reduction of Salmonella in animals and limitation of transmission from the environment.

Changes in prevalence of S. enterica serovars Pullorum versus Enteritidis and Typhimurium in the United States. As the prevalence of Pullorum in U.S. poultry flocks decreased as a result of a U.S. Department of Agriculture program (blue line), the prevalence of Enteritidis in humans increased (red line). Transmission of Enteritidis to humans from chicken eggs increased coordinately with the increased prevalence in poultry. During the period when the incidence of Enteritidis infections in humans was increasing, the incidence of Typhimurium infections in humans (green line) was relatively unchanged.
