Efficiency of a reheating step to inactivate Clostridium perfringens vegetative cells: How to measure it?

To estimate acceptable values of DA53, FTF and ST53, variability and uncertainty were taken into account separately. A two dimensional Monte Carlo simulation enabled the definition of 14 measure thresholds which made sure with a 97.5% confidence that less than 20%, 10% or 5% of exposed consumers in a specified population would experience diarrhea. The three proposed control measures, single and combined, were then compared by estimating the duration required to reach control measure thresholds. This required duration differs significantly from a control measure to the other, with the lowest duration for the combination of FTF and DA53.
