We just completed a corporate audit and we received a non-conformance for not having a validation study completed for our extended run time. Since I have been in my current food safety position for 9 years we have always run the same number of days, we run a 21 day cycle. Now I need to do a validation study. Would it be simple enough to use our micro testing results of our finished product that we test every four hours as an effective validation? Or should I also include some micro testing of the production line? We do micro testing after each clean-up and that is always quite good. Our product testing also has very good results. We produce a NRTE product that must be reconstituted in an oven (360F) or fryer at (360F) by the end user.
