Salmonella bacteria cause much of the food poisoning in the world, including an estimated 1,400,000 cases of salmonellosis in the United States each year. In Illinois about 1,500 to 2,000 cases of this foodborne illness are reported each year.
Salmonellais a general name for a group of about 2,000 closely related bacteria that cause illness by reproducing in the digestive tract.
How is it spread?
Salmonella live in the intestinal tracts of humans and other animals, including birds. Humans are usually infected by eating foods contaminated with animal feces. Contaminated foods are often of animal origin, such as beef, poultry, milk or eggs, but any food, including fruits and vegetables, may become contaminated. Contaminated foods usually look and smell normal and the contamination should not be expected to be visible.
Person-to-person transmission of salmonella occurs when an infected person's feces, unwashed from his or her hands, contaminates food during preparation or comes into direct contact with another person. Salmonellacan also be acquired directly from animals such as pets, birds, fish, dogs, cats and turtles. The U.S. Food and Drug Administration banned the sale of turtles smaller than 4 inches wide in 1975 to prevent the spread of salmonella.
