CREM Co’s use of PCS patented process applied for auditing kit can sample environmental surfaces as large as 30x60 cm (1x2 feet) in healthcare facilities with >80% recovery of the microbial burden. The method is simple, economical and quantitative. The spray-and-wipe procedure using a microfiber cloth permits wiping of smooth and uneven surfaces while also recovering microbes in even dried surface biofilms. The kit can assess the presence of bacteria and fungi/unit surface area sampled. The turnover time of the method remains similar to that of other available methods.
