A literature review indicated a mean D70C of 23 seconds with a 95th percentile of 125 seconds (based on 146 data points).
Cooking for 2 minutes at 70°C would achieve a mean (approximate) 6-log reduction in vegetative cells, but would not kill spores. In the same review, a mean D120C of 18 seconds was calculated for spores, with a 95th percentile of 161 seconds
