Volunteer for NIAID-funded clinical studies related to salmonellosis on ClinicalTrials.gov.
Salmonella bacteria can be found in food products such as raw poultry, eggs, and beef, and sometimes on unwashed fruit. Food prepared on surfaces that previously were in contact with raw meat or meat products can, in turn, become contaminated with the bacteria. This is called cross-contamination.
In recent years, the Centers for the Disease Control and Prevention has received reports of several cases of salmonella from eating raw alfalfa sprouts grown in contaminated soil. You also can get salmonella after handling pets, particularly reptiles like snakes, turtles, and lizards.
Salmonella can become a chronic infection even if you do not have symptoms. In addition, though you may have no symptoms, you can spread the disease by not washing your hands before preparing food for others. In fact, if you know you have salmonella, health care experts recommend you do not prepare food or pour water for others until laboratory tests show you no longer carry Salmonella bacteria.
