Evaluation of the Disinfection Effect of a Smoke Sterilizer
Since the entry of African swine fever virus into China,it had caused a great impact on the hog farming industry and promoted the development of biosecurity prevention and control.Disinfection,as one of its core,had been paid great attention,and many new disinfection techniques and equipments have appeared.In order to evaluate the actual effect of the smoke disinfector in the farm,this study used the smoke disinfector with glutaraldehyde disinfectant to treat African swine fever virus,Pseudorabies virus,Porcine repro-ductive and respiratory syndrome virus,which were infected with PAMs,Vero,and Marc-145 cells,respectively,and the inactivation ef-fect was judged by the erythrocyte adsorption test and direct observation method.Sterilization efficiency was also judged by fumigation treatments for Staphylococcus aureus,Salmonella and natural conditions of the enclosure.The results showed that the use of a smoke machine to atomize glutaraldehyde was effective in inactivating African swine fever virus,Pseudorabies virus,and Porcine reproductive and respiratory syndrome virus;At the same time for Staphylococcus aureus,Salmonella had a good sterilization effect on the enclosure closed treatment of 1 h,3 h,6 h,could achieve 96.43％,95.78％,91.23％of the sterilization efficiency.It provided a theoretical basis for the use of a fumigation disinfector with a glutaraldehyde disinfection method for biosecurity prevention and control in swine farms.
