标准范围

ISO 21528-2:2004规定了一种无需预富集的肠杆菌科计数方法。适用于人类消费和动物饲养的产品，以及食品生产和食品处理领域的环境样品。在37°C下培养后，通过在固体培养基中计数菌落进行计数。当所寻求的菌落数量预计超过每毫升或每克试验样品100个时，建议使用该技术。

ISO 21528-2:2004 specifies a method, without pre-enrichment, for the enumeration of Enterobacteriaceae. It is applicable to products intended for human consumption and the feeding of animals, and environmental samples in the area of food production and food handling.Enumeration is carried out by counting colonies in a solid medium after incubation at 37 °C.This technique is recommended when the number of colonies sought is expected to be more than 100 per millilitre or per gram of the test sample.
