New tool for disinfecting veterinary surveillance facilities
The article presents the results of experiments to establish the solubility of slaked lime depending on the temperature of the solution, as well as in strong electrolytes. It was found that the higher the temperature of the water, the lower the solubility of slaked lime. The solubility of slaked lime increases sharply, from 2.15 to 2.2 times, when 1 and 3% sodium chloride is added to the solution. With an increase in the concentration of sodium chloride in the solution, the solu-bility begins to decrease. The study of disinfection efficacy against Escherichia coli (pcs. 1257), Staphylococcus aureus (209-P), Mycobacteria (pcs. B-5) and Bac. cereus spores (pcs. 96) with 20% slaked lime with the addition of 1.3 and 5% sodium chloride showed a sharp increase in bactericidal activity in relation to these test cul-tures contaminated on various test surfaces. To reduce consumption and increase the resistance of the disinfectant, a foaming agent (PO-3A) was added to the slaked lime solution. It was found that the addition of 1.3 and 5% sodium chloride and 5% foaming agent to 20% hydrated lime enhances the disinfection efficiency against mycobacteria (pcs. B-5) and reduces the consumption of disinfectants by 2 times and a decrease in corrosion impact on metal products. Also, studies have estab-lished that solutions of the Penox1 composite agent are more effective than solu-tions of the phenol standard preparation 5.35 times with respect to the E. coli test culture (pcs. 1257). In addition, it was found that the effectiveness of Penox-1 solutions in the presence of high molecular weight protein, inactivated horse serum reduces bactericidal effectiveness by 3.2 times. The experiments showed the high efficiency of the solutions of the drug and the feasibility of further studies to study the bactericidal and disinfection effectiveness of the Penox-1 disinfectant in laboratory and industrial conditions. The successful implementation of disinfection measures largely depends on the availability of veterinary practice with highly effective, environmentally friendly disinfectants. In this regard, the search for new highly effective disinfectants remains relevant.
