Animal feeding stuffs: Methods of sampling and analysis - Detection and enumeration of Saccharomyces cerevisiae used as feed additive
24-11-2021
This document specifies general rules for the enumeration of Saccharomyces cerevisiae in feeding stuffs (additives, premixtures and compound feeds excluding mineral feeds) that contain Saccharomyces cerevisiae as a single microorganism component or in a mixture with other microorganisms. Applying the method to premixtures and compound feeds with critical amounts of copper demands a special procedure (see Annex A). The document is not applicable to mineral feeds, which are defined as complementary feeding stuffs composed mainly of minerals and containing at least 40 % crude ash (Regulation (EC) 767/2009) [3].There are different categories of feed samples:a)Additives containing about 1010 colony forming units (CFU)/g;b)Premixtures containing about 1011 CFU/kg;c)Compound feeds, meal or pellets which contain about 109 CFU/kg.
