Salmonella typhimurium

Salmonella are bacteria and a common cause of foodborne illness (sometimes called food poisoning). Infections caused by Salmonella result in more hospitalizations and deaths than any other foodborne illness in the United States. In recent years, large outbreaks of illness caused by Salmonella-contaminated eggs and poultry products have made headlines. Salmonella has been found in many foods, including ground beef, turkey, pork, tomatoes, sprouts, cucumbers, cantaloupes, and peanut butter – to name a few. Although contaminated food is the usual way of getting Salmonella, the bacteria also can be passed from animals to people. Older adults, infants, and people with weakened immune systems are more likely to have a serious illness.


Key Facts

  • CDC estimates 1 million people in the United States get sick from eating food contaminated with Salmonella.
  • Illness usually lasts 4-7 days and most people recover without treatment.
  • In rare cases, people may become seriously ill with Salmonella.
  • About 400 people die each year from Salmonella infection.
  • Children are the most likely to get food poisoning from Salmonella.
  • Salmonella causes $365 million in direct medical costs annually.
