Microbiological analysis of milk - Determination of presumptive Bacillus cereus - Colony count technique at 37 °C.

Summary

This standard specifies, in addition to DIN EN ISO 7932, a colony counting method for the determination of the number of presumptive Bacillus cereus (B. cereus, for short) at 37 °C using a PEMBA agar as culture medium for isolating. It is applicable for milk, milk products, ice cream and milk-based baby food. By using a MYP agar as culture medium for isolating the provisions given in DIN EN ISO 7932 apply. For the determination of a low number of presumptive B. cereus a most probable number technique (MPN method) with selective enrichment is available in DIN EN ISO 21871.

Notes

Applies in conjunction with DIN EN ISO 7932 (2005-03)
