Abstract：To monitor the microbial contamination situation of the experimental animal pedding, providing a basis to the management agency for the hygienic standard establish, and offering a reference to the manufacturing enterprise in pedding processing, sterilization, packaging, transportation and storage links. Methods According to the standard of GB4789-2010, the aerobic bacterial count, mould, escherichia coli and salmonella were detected to the pedding from different manufacturing enterprise. Results Forty nine of the pedding without sterilization exist mould and escherichia coli contaminate, but there had not detected the salmonella. The sterilization condition of 121℃ for 30min has the optimum effect to vary texture pedding, all microbiological indicator could not detectable under this method. Nineteen of twenty one sterilized pedding exist vary degree bacteria or mould contaminate, the escherichia coli and the salmonella were not detected. The mixed wood shavings exist bacteria contaminate after sterilized seven days, when store the pedding with the woven bag without seal, the bacteria can be detect in five days. When the pedding was used than one day, the quality of the bacteria could be up to 104 CFU/g but without the salmonella contaminate. Conclusion It is necessary to sterilize and store appropriate before the padding use, change the padding timely could improve the animal’s feeding environment and decrease the risk of the microorganism contaminate .
