“…До їх числа відносяться недотримання приписів щодо концентрації миючих і дезінфікуючих засобів, порушення режиму промивки, наявність залишків миючих засобів в обладнанні. Антибі-отики перешкоджають переробці молока, тому молочні заводи ретельно контролюють їх наявність у молоці (Zazharska, 2016).…”

Dairy cattle breeding in Ukraine is set the task that require a radical restructuring of the industry, bringing it out of a difficult crisis situation in order to increase the production of valuable food for the population and raw materials for industry The dairy industry is a very important part of all agricultural production. The socio-economic development of the state as a whole depends on the current situation in milk production. Quality milk must meet the requirements not only for physicochemical parameters (acidity, density, mass fraction of dry matter, protein, fat), but above all be safe, ie meet the current requirements for levels of contamination with microorganisms, the number of somatic cells, maximum permissible levels toxic elements, mycotoxins, residual amounts of antimicrobials, drugs and other substances. The quality and safety of cow's milk as a raw material is a global and unresolved issue for our country. The quality of milk cannot be improved in the process of its processing, so the milk quality management system at the enterprise should be focused on high-tech processes of its production, primary processing with the use of preventive measures. At present, the issue of high-quality milk production in Ukraine is urgent. Despite the trend, the population's demand for quality dairy products is increasing every year, so the issue of increasing the productivity of the dairy herd and milk quality through the use of modern high-tech conditions of keeping and milking. Therefore, the identification of factors influencing the process of milk production in farms is aimed at solving quality and safety problems and provides information on how to better and more effectively control hazards in the overall process.

“…Молоко є поживним середовищем, яке може бути легко забруднено мікроорганізмами (Kryzhanivskyi et al, 2005;Zazharska, 2016). Безпечність молока, що отримується на молочних комплексах передбачає відсутність в його складі будь-яких хімічних, фізичних або біологічних речовин, які становлять потенційну загрозу здоров'ю людини, але найбільшу загрозу виробництву молока становлять мікробіологічні чинники (Palii & Synytsia, 2016;Bogatko et al, 2018).…”

The main task of the dairy industry is the production of raw milk, the quality of which depends on the degree of bacterial background of milk and is achieved only if the regular cleaning and disinfection of milking equipment, dairy equipment. Milk is a good nutrient for microorganisms. The safety of milk that is obtained in dairy complexes provides for acceptable standards in its composition of any chemical, physical or biological substances that pose a potential threat to human health. The largest share of the listed factors belongs to microbiological contamination. The purpose of the work was to investigate the minimum bactericidal concentration of the acid detergent “Milkodez” on the test culture of microorganisms: S. aureus ATCC 25923, E. coli 055K59 No. 3912/41, P. aeruginosa 27/99. The study found that the acid “Milkodez” has bactericidal activity on the S. aureus culture test at dilution of a disinfectant 1: 268.8 and less and an active substance concentration of 0.371% or more at exposure of 2 minutes, for breeding 1:376, 5 and less (concentration of the active substance 0.265% and more) at exposure of 5 minutes and at dilution 1:1466.3 and less and a concentration of 0.0691% or more for 15 minutes. Minimal bactericidal concentration of the acid “Milkodez” on the test of E. coli culture at an exposure of 2 minutes amounted to 0.134%, at an exposure of 5 minutes. – 0.0493% and 15 minutes – 0.0352%. When the concentration of the agent is 0.012856% or more and its dilution is 1:7778.4 and less, throughout all investigated time ranges, there is no growth of the test culture P. aeruginosa. The use of the product at a temperature of 70 ± 5 °C allowed to inhibit the golden staphylococci at the concentration of the solution of the drug 0.371% for 2 minutes of action and 0.265% and 0.0691% – respectively within 5 and 15 minutes. At the same time, at the temperature of the solution of the Milkodez solution 70 ± 5 °C, the death of the E. coli was observed at the concentration of the acidic substance 0.0352%, 0.0493% and 0.134%, respectively, for 2, 5 and 15 minutes. The increase in the temperature of the solution from 20 ± 5 °C to 70 ± 5 °C resulted in the death of P. aeruginosa bacteria at a concentration of 0.01285% in all time ranges.
