Microbiology of food and animal feeding stuffs. Horizontal method for the enumeration of beta-glucuronidase-positive Escherichia coli - Colony-count technique at 44 degrees C using 5-bromo-4-chloro-3-indolyl beta-D-glucuronide PAS 015 whether internal or external1 Scope This part of ISO 16649 specifies a horizontal method for the enumeration of glucuronidase positive Escherichia coli in products intended for human consumption or for the feeding of animals. It uses a colony count technique at 44 C on a solid medium containing a chromogenic ingredient for detection of the enzyme glucuronidase. WARNING Strains of Escherichia coli which do not grow at 44 C and, in particular, those that are glucuronidase
