I am creating a hazard analysis for the creation of bulk polyethylene liners but I am have a hard time coming up with the 'germ' aspect. The liners come off a sterile roll of film and have no human contact until converted bags are folded. From what I see, the major germs would come from human conduct and poor hygiene. There is no food contact, no allergens in the process. We have a clean room process, hairnets, uniform jackets, hand washing etc.
What would limits of biological be from human touch to a sterile plastic bag (dirty hands, coughing, hair..etc) or a folding table?
