title: [Microbiological validation of a film system for monitoring total aerobic bacteria on surfaces and laboratory garments in controlled areas].
abstract: The microbiological control of the environment is a real issue inside the pharmaceutical production plants. Actually the most used methods are the Contact Plates and the Swabs. The purpose of this study is to evaluate the performance of a new "ready to use" method called Petrifilm SM (produced by 3M Laboratories). Petrifilm consists of a dry-rehydratable growth medium coated on a flexible film. Petrifilm is tested in comparison with Swabs and Contact Plates to monitor the microbiological pollution on labs surfaces and operator's overalls. The results obtained are comparable with the above mentioned methods, but with important advantages being less bulky, considerably time saving and highly reproducible. Hence, we think that Petrifilm S, can be successfully used instead of the other two more traditional methods.
