It is also important for medical device producers to carry out their bioburden tests for validation of sterilisation just prior to the product being sterilised. âIf product is being left around on shelves, companies need to redo the bioburden tests, as bioburden may have changed during storage,â said Rose.
Maintaining control of bioburden. Preventing, controlling and eradicating contamination in cleanrooms used for medical device production was the topic of a recent GMP seminar by sterilisation service provider Isotron. In medical device production low bioburden levels are key.
