Nontyphoidal Salmonellosis

Monitoring

  • The median duration of stool excretion of Salmonella is ~5 weeks for all age groups.
  • Of patients < 5 years of age, 2.6% excrete salmonellae for >1 year.
  • Routine follow-up cultures are not recommended after uncomplicated Salmonella gastroenteritis in immunologically normal patients.
  • Some states require one or more negative stool cultures (>48 hours after discontinuation of antibiotics, if given) before food handlers or health care workers with Salmonella gastroenteritis can return to work. A similar approach may be followed in day-care centers.
  • Consideration may be given to monitoring stool cultures in immunocompromised patients and attempting to eradicate carriage.
