SIS will be discussing their revised Compliance Guidelines for Appendix A (Lethality) and Appendix B (Stabilization) that will have new information on using pathogen modeling to evaluate heating and cooling deviations. Presenters from USDA, Academia, and Industry will discuss through case studies how to evaluate type I heating deviations (i.e., failure to meet critical limit of cooking CCP) and type II heating deviations (i.e., slow heating come-up time) in cooked/heat-treated meat and poultry products, and cooling deviations in cooked/heat-treated meat and poultry products. Specifically, the presentation for each type of process deviation will cover the following topics: FSIS requirements and/or policy for lethality or stabilization; the biological hazards associated with the process deviation; available predictive microbial models; performance of models; the appropriate approach and important considerations when using a model from a FSIS perspective; key information needed to conduct successive predictive microbial modeling; the level of pathogen growth or lethality that would be regulatory noncompliance and a public health concern; and actual process deviation scenarios.
