The presence of microbial contamination in the VWUDLJKWJUDGHÀRXUJLYHQWKHDVVXPSWLRQWKDWWKHHQGRVSHUP contributes 0% of the microbial contamination and bran and germ contains all potential contamination was calculated. Two simple methods for estimating the microbial contamination resulting from bran (including germ) were developed. First, we can assume the microbial content of the millfeed is the same as the microbial content of the bran in the straight JUDGHÀRXU6HFRQGXVLQJWKHPLFURELDOFRQWHQWRIWHPSHUHG wheat and assuming bran and germ make up 17% of the kernel weight carrying 100% of the microbial contamination as indicated previously.
