In most situations, a limit of NMT 10 CFU/100 ml (TAMC) would be acceptable for bioburden testing. If
a pre-filter is added as a precaution only and not because the unfiltered bulk solution has a higher bioburden, this limit is applicable also before the pre-filter and is strongly recommended from a GMP point of view. A bioburden limit of higher than 10 CFU/100 ml before pre-filtration may be acceptable if this is due to starting material known to have inherent microbial contamination. In such cases, it should be demonstrated that the first filter is capable of achieving a bioburden of NMT 10 CFU/100 ml prior to the last filtration. Bioburden should be tested in a bulk sample of 100 ml in order to ensure the Guideline on sterilisation of the medicinal product, active substance, excipient and primary container
