Bibliography

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 environmental and veterinary samples for: - the validation of alternative methods which can be used in particular in the framework of the official control; - the international acceptance of the results obtained by the alternative method.
