Relación con otras normas DIN:
This document specifies a horizontal method for the enumeration of beta-glucuronidase-positive Escherichia coli. It uses a colony-count technique after resuscitation using membranes and incubation at 44°C on a solid medium containing a chromogenic ingredient for the detection of the enzyme ß-glucuronidase. It is applicable to - products intended for human consumption; - products intendedfor feeding animals; - environmental samples in the area of food production and food handling; - samples from the primary production stage such as animal faeces, dust, and swabs.
