To use the calculator add your data to the input boxes.

Initial numbers of Listeria monocytogenes (mL)

e.g. 100
D value (seconds)* at test temperature
e.g. 4
Duration of heat treatment (seconds) at test temperature
e.g. 15



*The temperature at which the D value (decimal reduction value) was obtained (or calculated) must be the same as the temperature used for thermal processing.

NOTE! This calculator has been provided to enable the completion of a modeling exercise to investigate the probability of Listeria monocytogenes growing in cheese. To understand the context click here.
