Clostridium Difficile in Ready-To-Eat Salads, Scotland

Emerg Infect Dis. 2009 May;15(5):817-8. doi: 10.3201/eid1505.081186.

Abstract

Of 40 ready-to-eat salads, 3 (7.5%) were positive for Clostridium difficile by PCR. Two isolates were PCR ribotype 017 (toxin A-, B+), and 1 was PCR ribotype 001. Isolates were susceptible to vancomycin and metronidazole but variably resistant to other antimicrobial drugs. Ready-to-eat salads may be potential sources for virulent C. difficile.
