1.  How do I interpret the C. botulinum models?

The USDA Food Safety & Inspection Service (9CFR-Docket 95-033F) states that the cooling profile of a product can not result in growth of C. botulinum. In some instances, the PMP C. botulinum cooling model may predict a value of growth that is less than 0.3 log10. A predicted value lower than 0.3 log10 does not represent growth, because the log10 for one multiplication of C. botulinum is 0.3 log10 or greater.
