Evaluating disinfection methods for viruses and bacteria

Tuladhar E, Hazeleger WC, Koopmans M, Zwietering MH, Beumer RR and Duizer E. Residual viral and bacterial contamination of surfaces after cleaning and disinfection. Applied and environmental microbiology. 2012; 78: 7769-75.
 
Cleaning and disinfection are important facets of animal care and critical for multi-cat settings, such as veterinary clinics, breeding catteries, and shelters. These investigators examined the ability of various methods to disinfect surfaces of a multitude of viruses (e.g., norovirus, rotavirus, and others) and bacteria (e.g., Staphylococcus, Salmonella, and others) that vary in environmental stability. A single wipe with water, liquid soap, or free chlorine solution led to reduction in contamination but not total elimination of the pathogens. A second wipe with chlorine solution led to significantly more reduction in contamination. However, a single wipe with liquid soap followed by a single wipe with chlorine solution reduced contaminant levels significantly for most pathogens tested. [MK]
