This document defines general rules for the enumeration of enterococci (E. faecium) in feedingstuffs (additives, premixtures and compound feeds excluding mineral feeds) that contain enterococci as a single microorganism component or in a mixture with other microorganisms. Applying the method to 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 R767/2009) [4].
There are different categories of feed samples:
-
Additives containing about 1010 colony forming units (CFU)/g;
-
Premixtures containing 1011 CFU/kg;
-
Compound feeds, meal or pellets which contain about 109 CFU/kg;
The detection limit is defined in EN ISO 7218.
