Learning lessons from other critical industries.


Within dairy processing, sterile gas is of critical importance to the success of both the manufacturing process and the sensitive products being produced. However, there are no clear standards to define gas sterility and there is a general lack of harmonised "best practice" for maintaining process gas sterility in the high production environment of dairy processing.  


In light of this, we can look to the pharmaceutical industry for guidance on practices for controlling microbial hazards. Sterile gas is also of critical importance to pharmaceutical manufacturing processes, where the stakes of final product contamination are also high.  In pharmaceutical manufacturing, performance of critical microbial control processes are more defined and recognised by manufacturing plants and regulatory bodies.


The standards for sterilizing grade filtration systems and the associated integrity testing practices defined in pharmaceutical manufacturing can be transferred into the dairy industry to allow increased control of the hazards posted by airborne microbiological contamination
