factories that use the simulated experiments to determine their best
cleaning and sanitizing conditions should always be wary that
the experimental results are likely to underestimate the actual
values. Although the predicted level of viable microorganisms that
remained in situ after the cleaning and sanitizing process was relatively
low, the final contamination rate will be even lower since
the final step (step 6) involved spraying the surfaces of the
conveyor with 70% (v/v) ethanol that would reduce the bacterial
contamination rate further and perhaps to nearly zero
