Review Article THE OCCURRENCE AND SURVIVAL OF PARASITIC CAUSATIVE AGENTS IN SLURRY

Animal faeces are considered an important non-living vector of transmission of various infectious agents since they contain a broad spectrum of microorganisms. The fl oor of rearing facilities is a reservoir of infectious agents for kept animals. For this reason the slurry should be considered as infective in the case of an outbreak of any infectious disease. Parasitic infections are spread with slurry that normally occur on farms and enter the process of infection only through animal faces. From the aspect of environment protection from dangerous infections it is to keep in mind that the time and temperatures for anaerobic stabilization of slurry should be observed. These parameters must ensure reliable liquidation of all pathogenic germs. It is a well-known fact that the temperature and time of exposure of treated slurry have a direct infl uence on pathogen devitalization. The resultant substrate, which will undergo the process of composting when temperatures around 70 oC are reached, the composted heap is continually turned over after several days and possibly ground limestone is added (but it is not a condition), can be used for bedding in any animal species and category without fear of an outbreak of parasitic infection.
