Fig 8.

Graph presents the frequency of contaminated units and mean CFU in contaminated units for S. enterica, L. innocua, E. faecium, and E. coli under no cleaning and dry cleaning, depicting lower contamination with dry cleaning.

Density estimate of the prevalence of contaminated milk powder units (A) and the mean concentration within contaminated units (B) across all simulated production runs (n = 1,000 iterations) for each organism after a 2-log CFU contamination breach. Higher peaks mean more simulations fell into the range measured on the x-axis. In terms of contaminated units, Salmonella and E. faecium were the most similar in the absence of a towel-wiping intervention, but L. innocua was more similar to Salmonella when towel wiping was included.
