    Abstract - (Show below) - (Hide below)

    Gives the general principle and the technical protocol for the validation of alternative methods in the field of microbiological analysis of food, animal feeding stuff and related areas for: a. the validation of alternatives methods to be used for official control; b. the international acceptance of the results obtained by the alternative method.
