Objective To establish an effective method for the microbiological limit test of Yexiu Powder and mercury containing preparations. Methods Sodium thioglycollate was used to neutralize mercuric oxide so that the antibacterial activity in the test was destroyed. Centrifugal sedimentation-neutralization-membrane filtration method was used for the validation test of bacteria count, and neutralization-medium dilution method was used for the validation test of mold and yeast count and control bacteria inspection. Results In the validation tests of bacterial, mold and yeast count, the microbial recovery rates were not less than 70% both in test group and in diluted control group. In the tests of specified microbial species, the results met the standard. Conclusion The method is effective and feasible, which could be used for the microbiological limit test for Yexiu Powder and mercury containing preparations.
