This document describes methods for evaluation of production lots of Mueller Hinton broth by manufacturers of the dehydrated product. Performance of production lots is determined by testing defined organism/antimicrobial combinations. The results of testing must conform to defined quality control limit ranges for each combination of antimicrobial and ATCC quality control strain. Guidelines are provided for ranges of specific ion contents (cations and anions) that will provide results within the defined quality control limit ranges.
