Subject to some limitations, it is applicable to products intended for human consumption or the feeding of animals.The applicability of ISO 4833:2003 to the examination of certain fermented food and animal feeding stuffs is limited. For the examination of fermented food and animal feeding stuffs, other media and/or incubation conditions might be more appropriate.
