Antibiotic Resistance in Foodborne Illness: Good and Bad News

By Kelly Young

Edited by David G. Fairchild, MD, MPH, and Richard Saitz, MD, MPH, FACP, FASAM

Nearly 70% of Salmonella typhi, which causes typhoid fever, is resistant to quinolones, raising concerns that ciprofloxacin may lose its effectiveness against the disease, according to the CDC's 2012 survey of antimicrobial resistance to foodborne pathogens.

Among the other concerning findings:

  • About one in four Campylobacter infections are resistant to ciprofloxacin.

  • Resistance to ceftriaxone is making severe Salmonella infections more difficult to treat, particularly in children.

And on a better note:

  • Resistance to ceftriaxone and quinolones is still considered rare.

  • Multidrug resistance in Salmonella infections has actually declined over the past decade, from 14% to 9%.
