GSO ISO 4831:2010 Scope
This Gulf standard gives general guidelines for the enumeration of coliforms. It is applicable to:
- Product intended for human consumption and for the feeding of animals, and
- Environmental samples in the area of food production and food handling.
Enumeration is carried out by calculation of the most probable number (MPN) after incubation in a liquid medium at 30oC or 37oC.
Note The temperature is subject to agreement between the parties concerned. In the case of milk and milk products, the temperature of incubation is 30oC.
This enumeration method is applicable when the sought is expected to be in range 1 to 100 per milliliter or per gram of test sample.
A limitation on the applicability of this Gulf standard is imposed by the susceptibility of the method to a large degree of variability. The information given in Clause 11 provides guidance on the applicability of the method and on the interpretation of the results.
