Bacterial contamination in the dairy industry can have major implications for manufacturers and consumers. The importance of contamination control has been put into sharper focus by the growth of the 'natural' dairy products market. With a decrease in the use of preservatives natural dairy products can become ideal environments for bacterial growth.
To support the prevention of contamination, sterile gas is used in the production and packaging processes. Sterile gas filter systems are also used to ensure the sterility of the gas.
Filters must be fit for purpose and capable of delivering sterility throughout their service lifespans. It is vital that any filter failure is detected as soon as it occurs. Integrity testing is a means of achieving this, and through the correlation of an integrity test to a live bacterial or viral challenge, integrity testing can give you assurance of filter performance within an application.
This whitepaper evaluates the effectiveness of the aerosol challenge for the integrity testing of sterile gas and air filtration solutions.
