The status and problems of national standards of microbiological examination has been summarized. 163 food standards of microbiological examination have been discussed and reviewed respectively by technical experts during the clean-up program. As a result, a catalogue of 31 food safety standards for microbiological examination (GB 4789) was proposed. In order to provide a better recognition of the clean-up program and comprehension of the construction approaches on food safety standard system for the administration department and food industry, this paper explores the problems of current standards and the corresponding solutions on the basis of summarizing and analyzing results of the clear-up program.
