Abstract
Investigations were carried out under operating conditions of Field Composting Factory in Brezno (Slovak Republic) to determine the effect of anaerobic stabilization of organic wastes from public areas on the survival of model helminth Toxocara canis and Ascaris suum eggs. Due to anaerobic conditions, low temperature, low C:N ratio and changes in physical and chemical properties of organic waste, less than 64% of A. suum eggs remained viable after 150 days of stabilisation. The anaerobic stabilisation had a greater effect on the viability of T. canis eggs than on A. suum eggs. The infectivity of T. canis eggs was confirmed by a follow-up experiment in laboratory mice. A small number of T. canis larvae were found in their brain and muscles on day 28 after infection. The results refer to the risks of dissemination, survival and potential spread of endoparasitic developmental stages in the environment through organic wastes subjected to low temperature stabilisation.
