In Guangxi of China, GMP (Good Manufacturing Practice) have been introduced in sugar mills since 2005 to comply with the requirements of the government administration, the clean zone was defined, and physical isolation was enforced as a procedure in sugar production. However, the rate of microbial detection in sugars did not reduce as expected. In this paper, the microbiological investigation and microbiological harm analysis of sugar clean zone in three sugar mills in Guangxi were reported. The methodology of investigating microbial species isolated from sugar cane clean area and its surrounding environment in sugarcane mill, as well as the distribution pattern of environmental microorganisms combined with air flow analysis and microbiological analysis were introduced. The research results provide the basis for control theory and control technology in the analysis of microbial harm in sugarcane mill.
