text: You will need to hire an experienced microbiologist to do this. \n\nIt will probably require an initial investment of 100,000 to a million dollars depending on your facilities. After the lab is set up you need to validate your equipment and compose a set of standard operating procedures. \n\nIt would probably be cheaper to outsource your micro testing. QA testing lab companies will have their own validated methods, a staff of microbiologists, and (in some cases) they'll even pick up your samples right from your processing facility.
