05/28/24 Public Health Education Topic: Salmonella


Salmonella are bacteria that make people sick. Most types of Salmonella cause an illness called salmonellosis while some other types of Salmonella cause typhoid fever or paratyphoid fever.

CDC estimates Salmonella bacteria cause about 1.35 million infections, 26,500 hospitalizations, and 420 deaths in the United States every year. Food is the source for most of these illnesses.

  • Most people who get ill from Salmonella have diarrhea, fever, and stomach cramps.

  • Symptoms usually begin 6 hours to 6 days after infection and last 4 to 7 days.

  • Most people recover without specific treatment and should not take antibiotics. Antibiotics are typically used only to treat people who have severe illness or who are at risk for it.

  • Some people’s illness may be so severe that they need to be hospitalized.

How do people get infected?

Salmonella lives in the intestines of people and animals. People can get Salmonella infection from a variety of sources, including:

  • Eating contaminated food or drinking contaminated water

  • Touching infected animals, their feces, or their environment
