Clostridium difficile is a gram-positive, spore-forming anaerobic bacillus that is associated with diarrheal disease. C difficile is shed in the feces of affected individuals and its spores can survive on surfaces for prolonged periods of time. These spores can contaminate a hospital environment by spread through health care workers and suboptimal environmental cleaning practices. We report an outbreak of health care facility-onset C difficile infection that was eventually linked to contaminated mop pads after a laundry machine malfunction.
