Abstract
Effective sanitization is important in viral epizootic outbreaks to avoid further spread of the pathogen. This study examined thermal inactivation as a sanitising treatment for manure inoculated with high-pathogenic avian influenza virus H7N1 and bacteriophages MS2 and 6. Rapid inactivation of high-pathogenic avian influenza virus H7N1 was achieved at both mesophilic (35?C) and thermophilic temperature (45 and 55?C). Similar inactivation rates were observed for bacteriophage 6, while bacteriophage MS2 proved too thermo-resistant to be considered a valuable indicator organism for avian influenza virus during thermal treatments. Guidelines for treatment of litter in the event of emergency composting can be formulated based on the inactivation rates obtained in the study.
