48、s in different laboratories and to contribute towards the protection of the health of the laboratory personnel by preventing risk of infection.When conducting microbiological examinations for cosmetic products, it is especially important that: only those microorganisms which are present in the sampl

49、es be isolated or enumerated; the microorganisms do not contaminate the environment.In order to achieve this, it is necessary to pay attention to personal hygiene and to use working techniques which ensure, as far as possible, exclusion of extraneous contamination.Since, in this document, it is possible to give only a few examples of the precautions to be taken during microbiological examinations, a thorough knowledge of the microbiological techniques and of the microorganisms involved is essential. It is important that the analyses be conducted
