ОЦЕНКА ЭФФЕКТИВНОСТИ ДЕЗИНФЕКЦИИ ПОВЕРХНОСТЕЙ ОБОРУДОВАНИЯ ПРЕПАРАТОМ ФУМИЙОД В ЖИВОТНОВОДЧЕСКИХ И СВИНОВОДЧЕСКИХ ПОМЕЩЕНИЯХ В ПЕРИОД САНИТАРНОГО РАЗРЫВА

Abstract

The purpose of the work is to evaluate the effectiveness of preventive disinfection of surfaces of technological equipment with fumigation aerosols of the “Fumiyod” drug in livestock and pig premises during the san-itary break. The work was carried out in livestock and pig farms of the Volosovsky district of the Leningrad region. Disinfection of technological equipment in experimental facilities for growing calves and piglets dur-ing the sanitary rupture (after the mechanical cleaning and washing of equipment with hot water + 600С) was carried out by fumigation aerosols of the “Fumiyod” using iodine blocks by sublimation for 3 hours after expo-sure. Control was provided by similar facili-ties after mechanical cleaning and washing of equipment with hot water + 600С. Test objects – metal surfaces , concrete, tile, wood, rubber, metlakh tiles. The effective-ness of disinfection of surfaces of technolog-ical equipment was evaluated by test of the bacteria of the Escherichia coli group (BGEC) and staphylococcus. To isolate BGEC, KODA medium, or Endo agar, was used to indicate staphylococci — yolk-salt agar (6.5% NaCl). In an experiment in live-stock and pig breeding facilities, for the con-trol of the quality of disinfection for the iso-lation of BGEC, the “Fumiyod” effective disinfection of smooth surfaces at a concen-tration of 0.10 g / m3 for 1 h, rough surfac-es, respectively, 0.20 g / m3 for 1 hour for the isolation of staphylococci, respectively, in a concentration of 0.1-0.20 g / m3 of smooth and rough surfaces at an exposure of 3 hours were carried out. For the control (after washing the equipment with hot water and without disinfection) in washes from smooth and rough surfaces of equipment in pig breeding and livestock buildings BGEC were allocated in 70%; staphylococci, re-spectively, in 100% and 95% of the samples.
