The incidence of Salmonella in Georgia has increased slightly over time , with certain areas, especially in the southern parts of the state, having higher incidence (Figure 2). Mode of Transmission : Ingestion in food derived from infected animals or food contaminated by feces of an infected animal or person ; environmental or person-toperson exposures. Common vehicles include undercooked eggs, raw milk, contaminated water, meat and poultry. Pet turtles , iguanas and chicks are common sources for infants and children exposures.
