Determination of microbicides efficiency at meat processingplants
Journal Title: Бюлетень "Ветеринарна біотехнологія" - Year 2017, Vol 30, Issue
Abstract
Introduction. Obtaining meat and meat products of high quality requires adherence to sanitary and hygienic norms of the processing facilities during meat-processing activities. The level of pollution reduces the efficiency of disinfection since it is slowing down penetration of chemicals into microorganisms and blood-based pollution increases dilution of disinfectants. In addition, organic agents reacting with a disinfectant, absorb or inactivate it creating new substances which don’t damage microorganisms. Therefore, preliminary mechanical clearing and washing significantly increase the efficiency of disinfection. The goal of the work. To conduct a comparative analysis of various disinfectants’ efficiency levels use of different active compounds and pollution levels. Materials and methods. According to the recommendations, in our work we used: 0,5 % Geocyd, 0,25 % Orgasept and 0,25% Virosan. E. coli strain 1257 and S. aureus strain 209-P were used as testing cultures. Suspension was introduced into the polluted surface, containing fodder, manure and milk in the rate 0,5g of dirt per 1 litre of bacterial suspension. The contaminated mass was applied on 1 m2 surface with different layerʼs thickness within 0.5; 1.5; 3.0; 4.0; 5.0 and 6.0 mm. Results of research and discussion. Analyzing the results, it is worth noting that the highest expense rate of the spray material is referred to the disinfectants Geocyd (0.5%) and Virosan (0.25%). 1.1 - 1.5 litre of this spray material was used per 1 m2 of surface with E. coli and S. aureus in 4.5 mm layer of dirt. The research showed that such amount of mass could not be detained on the cultivable area.0.5 % Geocyd has bactericidal effect in the rate of 0.3 liters per 1 m2 of surface with 0.5 mm layer of pollution. 0.25 % Orgasept has a destructive effect on all testing cultures in the surface with 0,5 mm polluted layer. To disinfect 1,5mm layer of pollution, it is recommended to use 0.3 litre of Orgasept. In comparison with Virosan (0.25%), it destroys the causative agent within 1-3 hours. Conclusions and prospects for further research. It was found that Geocyde has bactericidal effect in the rate of 0.3 liters per 1 m2 of surface with 0.5 mm layer of pollution. 0.25 % Orgasept destroyed all test-cultures on the 0.5mm polluted surface.
