Certain bacteria in the group Salmonella cause salmonella food poisoning. These bacteria live in the intestines of humans and animals. Human infection results when food or water that has been contaminated with infected feces is ingested. Salmonella food poisoning is commonly caused by: undercooked chicken, turkey, or other poultry, undercooked eggs, unpasteurized milk or juice, contaminated raw fruits, vegetables, or nuts.
To diagnose salmonella food poisoning, your doctor will do a physical examination. They may check if your abdomen is tender. They may look for a rash with small pink dots on your skin. If these dots are accompanied by a high fever, they may indicate a serious form of salmonella infection called typhoid fever.
