How does one possibly validate pre-requisites such as :
Raw material acceptance protocols (namely visual inspections in order to detect foreign body contamination )
Supplier assurance
Foreign body control procedures in high care production areas
etc etc
I mean validation, not verification through internal auditing for example.
When I ask this question people give me validation of clean processes to eliminate the risk of allergen cross contamination OR temperature checks in serveral places of a full chiller together with bibliography with regards to chilled temperatures to validate chilled storage as a prerequisite.
Those are easy, but, how on earth does one validate prerequisites like the ones I mention above? is this even possible? (again , not verification )
many thanks all
