, except for plating on solid medium to quantitate recovery. A few 100-mL rinses are assumed, but the volume and number of rinses are issue to validation. Every validation operate really should be executed independently at the very least 3 times.
The inspection ought to contemplate the relationship between the organisms present in the samples as well as the possible for that existence of other objectionable situations.
