Abstract: In order to survey the moon cakes with meat products in the microbial contamination,two kinds of moon cakes with meat products were chosen to detect bacteria and moulds by using the national standard methods of GB4789.15 — 2003 and GB4789.2—2003,and the moisture contents in the two kinds of moon cakes with meat products were also detected.Bangladesh red agar and potatoes agar(PDA) were used for counting and identification of mold,respectively.After separation and purification,moulds colony was observe and their cell morphologies were observed under microscope to identify their species.Results showed that the two kinds of moon cakes in the values of total bacteria and coliform bacteria are in line with national standards.There are main three species of moulds in the two kinds of moon cakes with meat products.They are Aspergillus glaucus,Aspergillus versicolor and Aspergillus flavus.
