Percent pathogen transfer from initial to secondary coupon at high and low pathogen concentration. Individual transfer scenarios (direct vs. indirect) are shown. The percent transferred when no wash or decontamination step was included is represented on the X-axis, with the percent transferred following a wash or decontamination step represented on the Y-axis. Values for individual pathogens were averaged (n = 3) prior to plotting. Linear regression lines were plotted with the slope of each line indicated. a Percent pathogen transfer at high initial pathogen concentration. S. aureus outlier results are indicated with gray arrows. B) Percent pathogen transfer at high initial pathogen concentration excluding S. aureus. b Percent pathogen transfer at high initial pathogen concentration excluding S. aureus. c Percent pathogen transfer at low initial pathogen concentration. P. aeruginosa outlier results are indicated with a gray arrow. D) Percent pathogen transfer at low initial pathogen concentration excluding P. aeruginosa
