BS EN 15788:2021

This standard BS EN 15788:2021 Animal feeding stuffs: Methods of sampling and analysis - Detection and enumeration of Enterococcus (E. faecium) spp. used as feed additive is classified in these ICS categories:

• 65.120 Animal feeding stuffs

This document specifies general rules for the enumeration of enterococci (E. faecium) in feeding stuffs (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 premixtures and compound feeds with critical amounts of copper demands a special procedure (see A.2). 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) [4]. There are different categories of feed samples: a) Additives containing about 1010 colony forming units (CFU)/g; b) Premixtures containing 1011 CFU/kg; c) Compound feeds, meal or pellets which contain about 109 CFU/kg.
