Qualification of Disposable Petri Dishes

Aspects to be covered for performing the qualification of Petri dishes used in Microbiological Laboratory?



Dear Kiran
here what i can emphasize on is to check the washing of petri dishes, concentration and selection of detergent used, residues of detergent it can be very critical as the detergent may have a bacteriostatic effect and may inhibit the bacterial growth. Vice versa inadequate cleaning may also enhance the bio burdon. The other things to be taken in consideration are the proper sterilization of these dishes, personnel qualification for washing, handling, sterilization and storage of petri dishes as per SOP.
