T/ZNZ 252-2024 Isolation, identification, and detection of virulence genes of Bacillus cereus in formula milk powder
Basic Information
Scope
Main technical content: This document specifies the equipment and materials, culture media and reagents, sample preparation and strain isolation and identification, plate counting method (first method), MPN counting method (second method), PCR detection of virulence genes, and biosafety requirements for the isolation and identification of Bacillus cereus in formula milk powder. This document is applicable to the isolation and identification of Bacillus cereus in formula milk powder and the detection of virulence genes. The first method of this document is applicable to the detection and counting of Bacillus cereus in formula milk powder samples with a high content of Bacillus cereus; the second method is applicable to the detection and counting of Bacillus cereus in formula milk powder samples with a low content of Bacillus cereus.
