Disinfection Effect Evaluation Of Potassium Monopersulfate Particles

Disinfection is the most important method of prevention first policy and the central content of animal health care system.In this study,we employed the Potassium Monopersulfate Particles(PMP)as a disinfectant and tested the effect of sanitizing treatment via PMP in laboratory and farm plant.The results show that:PMP treatment effectively disinfected Newcastle disease virus(NDV),Escherichia coli(E.coli)and staphylococcus aureus(S.aureus).Suggest that PMP is a broader spectrum,effective,safe and environmental friendly veterinary disinfectant.The details of study content as blew:1 Disinfection effective test against NDV by PMP treatment.Employ 1%Sodium thiosulfate as neutralizer,NDV infected chicken embryonated eggs(CEE)as negative control,5 g/1 disinfectant treatment CEE as positive control and the case groups are 10,5,2.5 and 1 g/1 PMP treatment CEE.Same as the positive control,PMP disinfected all of the NDV at 4 of our tested concentration in 5 min.Hence,PMP is a high effective and fast disinfectant at low concentration(1 g/1).Meanwhile,we found even 10g/1 PMP treatment does not affect the development of CEE.2 Disinfection effective test against microorganism by PMP treatment.Employ 1%Sodium thiosulfate as neutralizer,E.coli and S.aureus as target bacterial,1:200 virkon solutions as a positive control disinfectant.PMP was diluted at 1:100,1:200,1:400 and 1:1000 for the case groups' treatment.Results show that PMP could disinfect the E.coli and S.aureus at all of 4 tested concentration in 5 min.A time course experiment also is performed.We studied the lowest effective concentration of PMP at 5,10,15,30 and 60 min treatment.The lowest effective concentration of PMP against E.coli is 2.5 g/1 for 5 min treatment and 0.1563 g/1 for 60 min treatment.Compare to E.coli,S.aureus is more sensitive to PMP.The lowest effective concentration of PMP against S.aureus is 0.526 g/1 for 5 min treatment and 0.1563 g/1 for 60 min treatment.Results suggest that PMP is a fast and highly effective disinfectant against microorganism.3 Disinfection effective test of PMP at farm plants.For further confirm the disinfect effecting of PMP at farm plants,we selected 4 animal houses from 2 chicken farms.Then we disinfected the walls,the grounds,the drinkers and the cribs by PMP.1:100 and 1:200 diluted PMP could disinfect over 99.9%of the microorganism in 5 min.1:400 diluted PMP could disinfect over 99.9%of the microorganism in 30 min.Hence,we conclude that PMP could highly effective disinfected microorganism in a farm plant under the recommended concentration(1:200).
