I want to check the area cleaning effectiveness in ISO 8. I will take the swab sample from floor and wall for analytical testing. Should I collect the swab for microbial testing also. I have done the disinfectant efficacy test to clean the production area.
@ajaybangalroe yes, it is compulsory to check the area for cleanliness.
this is gonna be so expensive and time consuming, doing microbial test each time after a complete cleaning
