1   Scope This European Standard defines general rules for the enumeration of probiotic pediococci in feed samples (additives, premixtures and feeding stuffs) that contain pediococci as a single bacterial component or in a mixture with other microorganisms. This standard is not applicable for mineral feeds which are defined as complementary feeding stuffs composed mainly of minerals and containing at least 40% crude ash (Council Directive 79/373/EEC) [3]. There are different categories of feed samples:

a) Additives containing about 10 10 (colony forming units) CFU/g

b) Premixtures containing about 10 8 CFU/g

c) Feeds, meal or pellets, which contain about 10 6 CFU/g and include complete feeding stuffs, and milk replacers.

The detection limit is as defined in EN ISO 7218.
