[Assessment of probiotics according to the international organizations (FAO/WHO)].

The guidelines of international organizations (FAO/WHO) are presented in the paper for the purpose of estimation of probiotic properties of the strains of microorganisms as well as functional food products in respect of their influence on health. Modern scientific researches served as the basis for minimum requirements necessary for the competence of probiotic status. The chart of the experiment sequence is presented that has to be used for probiotics estimation: bacteria systemizing with the use of phenotype and genetic techniques, description of functional properties of the probiotic and estimation of its safety. The in vitro tests for determination of safety of probiotics are described.
