| Abstract: |
| Modern animal epidemics have predominantly occurred in the livestock industry, which has become the focus area for the prevention and control of animal epidemics in China's Biosafety Law. Livestock manure has long been assumed to be an important source of dangerous biological agents(DBAs). This paper reviewed the current scientific understanding of the characteristics, occurrence, and environmental behavior of typical DBAs(antibiotic resistance genes and viruses)in the disposal and treatment of livestock manure from the perspective of China's Biosafety Law. We also discuss the current scientific deficiencies, new research directions, and provide references that aim at improving biological safety in the livestock industry, preventing animal epidemics, and controlling the spread of DBAs from the livestock industry to the environment. The main recommendations are as follows:to comprehensively characterize the occurrence and fate of DBAs in the disposal of livestock manure with regard to microbiota community structure as identified by nucleic acids(such as antibiotic resistance genes) → nucleic acids + proteins(such as viruses) → cell structure(such as drug-resistant bacteria); to develop methods for the identification, classification, and rapid detection of emerging DBAs in livestock and poultry manure; to research and develop targeted technologies for DBAs control in the treatment process; and strengthen the research on collaborative control technologies for organic pollution, inorganic pollution, and biological pollution from livestock and poultry manure. |
