Maintaining a high level of sanitation is essential for animal research facilities. Researcher and technician compliance, including appropriate application, is a common problem. Historically, our standard protocol included using a Chlorine Dioxide disinfectant (Clidox-S) followed by a wipe down with a less corrosive cleaner (Quatricide PV). The Clidox-S required a five-minute contact time, was corrosive to our stainless steel equipment and required a followup cleaner. We identified an Accelerated Hydrogen Peroxide based disinfectant (Rescue Ready to Use – RTU) that is both a disinfectant and a cleaner. It requires a one-minute contact time, claims to be non-corrosive to stainless steel equipment and comes in a convenient pre-soaked wipe format. Before deciding which product would best suit our needs we conducted side by side testing, for effectiveness.
We then considered many other factors: expense (wipes in particular), shorter contact time (improved compliance), less corrosion of our stainless equipment (long-term cost savings), safety of the product (no aerosol), longer shelf life (up to 2 years), the need for only one chemical (no cleaner required), ease of use (wipes) and user preference. Our final determination was that while the Rescue Ready to Use was more expensive, especially the wipes; it was an effective agent and offered many advantages that justified the increase in cost. We continue to see positive effects based on quarterly health monitoring, yearly agar testing and equipment longevity. In combination with a comprehensive training program our change to Rescue Ready to Use has ensured a high level of sanitation and cleanliness in our facility.
