Recovery of gastrointestinal swine parasites in anaerobic biodigester systems

摘要: Solid and liquid wastes from livestock operations represent important challenges for animal production regarding their impact in the environment public health. Parasitological tests performed on 80 samples of affluent effluent waters three anaerobic biodigestors with flexible structure swine farms Caldas - Colombia, showed presence Isospora suis (45%), Eimeria (42.5%), E. espinosa (35%), Strongyloides ransomi (28.8%), perminuta (12.5%), cerdonis (3.8%), porci (2.5%). The additional finding eggs Taenia spp. 10% was probably caused by a connection between human sewage system biodigester. Although we observed mean decrease 65.6% parasites, these levels were insufficient to meet minimum requirement set Engelberg's guidelines water quality. This study demonstrates serious environmental that an inadequately treated wastewater represents, has implications resources
