Salmonellosis is a major cause of gastrointestinal disease in humans. This condition is caused by cross-species (zoonotic) Salmonella bacteria, resulting in illness and possible death, especially in young and immunodeficient subjects. Poultry products and table eggs are viewed as potential sources of Salmonellosis in humans. Reducing incidence of Salmonella in poultry flocks reduces the risk of human disease.
