The Harmonized Microbial Limits Test (MLT) is Employed in The us, Europe and Japan as the main biological release test for non-sterile strong oral products supposed for human use [1-four]. This is a compendia test that means that it is revealed and meant for use “as is” with little if any variation with the method. The objective of the harmonization from the test was in order to avoid avoidable testing duplication which happened before the Worldwide harmonization exertion in 2009 [one,two].
