本欧洲标准定义了将含有肠球菌（屎肠球菌）作为单一微生物组分或与其他微生物混合的饲料样品（添加剂，预混物和饲料）中的肠球菌计数的一般规则。本标准不适用于矿物饲料，定义为主要由矿物质组成的补充饲料，含有至少40％的粗灰分（理事会指令79/373/EEC）[3]。 饲料样品有不​​同类别: a）含有约1010个菌落形成单位（CFU）/ g的添加剂; b）含有108 CFU/g的预混物; c）含有约106 CFU/g的饲料，膳食或丸剂，包括完整的饲料和牛奶替代品。 检测限定在ISO 7218中

This European Standard defines general rules for the enumeration of enterococci in feed samples (additives, premixtures and feeding stuffs) that contain enterococci (E. faecium) as a single microorganism component or in a mixture with other microorganisms. This standard is not applicable to mineral feeds which are defined as complementary feedingstuffs 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 1010 colony forming units (CFU)/g; b) Premixtures containing 108 CFU/g; c) Feeds, meal or pellets which contain about 106 CFU/g and include complete feeding stuffs,and milk replacers. The detection limit is as defined in ISO 7218.
