Abstract
The article presents the results of veterinary-sanitary and sanitary-bacteriological studies of multicomponent (complex) composts based on organic animal waste during prolonged exposure to natural conditions. As test microorganisms, museum cultures of Escherichia coli (pcs. 1257), Staphylococcus aureus (strain 209-P), and mycobacteria (pcs. B-5) were used.
It has been established that during prolonged aging of a multicomponent compost mixture based on organic waste from animal husbandry, the temperature in various layers of the shoulders rises, the pathogenic and indicator microflora perishes depending on the temperature.
When the temperature of the compost mass increases from 50 to 59 ° C, the viability of the indicator microflora is maintained for 80 ... 90 days, at a temperature of 56 ... 62 ° C - 50 ... 60 days, respectively. At lower temperatures, bacteria of the Escherichia coli and Salmonella group survive up to 240 days, staphylococci - up to 270, and tuberculosis pathogens up to 360 days or more.
