Scope
This part of ISO 16649 specifies a horizontal method for the enumeration of β-glucuronidase-positive Escherichia coli in products intended for human consumption or for the feeding of animals. It uses a colony-count technique at 44 ℃ on a solid medium containing a chromogenic ingredient for detection of the enzyme β-glucuronidase. WARNING — Strains of Escherichia coli which do not grow at 44 ℃ and, in particular, those that are β-glucuronidase negative, such as Escherichia coli 0157, will not be detected.
