Illness is usually worse in very young and very old people.
The bacteria can be found in foods such as raw chicken, turkey, beef, pork, other meat, eggs, and unpasteurized milk products. Infected people may carry the bacteria in their feces for several weeks or more, even after they feel better. Symptoms can be mild or severe. Sometimes the blood or other body sites become infected. Some people can have salmonellosis but have no symptoms at all.
