This document specifies a horizontal method for enumeration of microorganisms that are able to grow
and form colonies in a solid medium after aerobic incubation at 30 °C.
The method described in this document is applicable to:
- products intended for human consumption;
- products intended for feeding animals (including pets);
- environmental samples in the area of food and feed production and handling;
- all samples from the primary production stage.
This technique is suitable for, but not limited to, the enumeration of microorganisms in test samples
with a minimum of 10 colonies counted on a plate. This corresponds to a level of contamination that is
expected to be higher than 10 cfu/ml for liquid samples or higher than 100 cfu/g for solid samples.
