Full Description

This document is applicable to fertilizing products, which are classified as PFC 1(A) and PFC 1(B) or the PFC 1(A) and PFC 1(B) component in PFC 7 of Regulation (EU) 2019/1009 [1]. However, the present method was not validated for blends.

This document specifies a colony-count technique at 44 C on a solid medium containing a chromogenic ingredient for the detection of the enzyme -glucuronidase. The method is based on ISO 16649-2 [4].

Strains of Escherichia coli which do not grow at 44 C and, in particular, those that are -glucuronidase negative, such as Escherichia coli O157, will not be detected. Detected microorganisms are presumptively determined -glucuronidase-positive Escherichia coli, since some Enterobacteriaceae, in particular Shigella and Salmonella, can also show -glucuronidase activity at 44 C.

All current amendments available at time of purchase are included with the purchase of this document.
