Animal feeding stuffs: Methods of sampling and analysis - Isolation and enumeration of presumptive Bacillus spp.

inactive
Organization: NEN
Publication Date: 1 February 2020
Status: inactive
Page Count: 20
ICS Code (Animal feeding stuffs): 65.120
scope:

This documentdefines general rules for the enumeration of bacilli in feeding stuffs (additives, premixtures and compound feeds including mineral feeds) that contain bacilli as a single microorganism component or in a mixture with other microorganisms. 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 to 1010 CFU/kg.

The detection limit is defined in EN ISO 7218.
