And if This is actually the circumstance, when this kind of contaminated merchandise is subjected to sterility tests working with correct culture media, it is anticipated that the contaminating organisms will increase and generate colonies (in the case of sound lifestyle media plates) or turbidity and/or gas production (for broth cultures) that provides impetus towards the existence of contaminating microorganisms.
