We have a crisis management procedure in the event of a crisis but one of our customers are looking for a special event swabbing procedure. I have read a lot on what to do in the event of roof leak, drain back up, pipe leak, etc. I know what to do with the product and that we need to swab for Salmonella and Listeria after but, I am having difficulty putting this together into a procedure. Do I have to list each event and the what we will do under each special circumstance? Do you make a new procedure for this or add it to your Crisis Management Procedure? How do you know how many swabs are sufficient to take after? Any help or advice would be greatly appreciated.
