Summary

The following heat treatments prevented growth and toxin production during 90 days provided that the storage temperature was no higher than 12 deg C: 75 deg C for not less than 1,072 minutes, 80 deg C for not less than 230 minutes, 85 deg C for not less than 36 minutes, and 90 deg C for not less than 10 minutes. Following heating at 70 deg C for 2,545 min. and storage at 12 deg C, growth was first observed after 22 days. Predictions from the model provided a valid description of the data used to generate the model, and agreed with observations made previously.
