To effectively strengthen the animal epidemic prevention barrier, ensure the high-quality development of the entire city's animal husbandry and public health safety, the Shiyan City Animal Disease Prevention and Control Center, while comprehensively promoting the compulsory immunization of animal diseases, organized professional technical personnel to go to the front line, and carried out a special action to investigate hidden dangers, eliminate risk sources, and protect safety, fully safeguarding animal husbandry breeding safety. Precision immunization builds a defense line, leaving no dead angle in immunization. Strictly following the requirements of the "2026 National Animal Disease Immunization Technology Guidelines," comprehensive compulsory immunization work for major animal diseases such as highly pathogenic avian influenza, swine fever, and small ruminant plague was carried out. Adhering to the principle of "no village missed, no household missed, no livestock and poultry missed, no needle missed," the procedural immunization and "vaccination first, then compensation" policy were strictly implemented for large-scale breeding farms, while a whole-village promotion and network-style centralized immunization method was adopted for scattered households, ensuring that the immunization density of livestock and poultry reached 100%, and the herd immunity density and antibody qualification rate were both maintained above the national standard. Strictly following the operation procedures, achieving "one animal one injection," and simultaneously doing a good job in livestock and poultry identification wearing and establishing immunization file standards, the immunization process was made fully traceable, building a solid animal immunization protection barrier from the source. Comprehensively investigate and eliminate hidden dangers, close-loop rectify risk sources. A special investigation work group was formed, deeply investigating various breeding farms (households), livestock and poultry trading markets, slaughterhouses, and harmless treatment sites within the jurisdiction, comprehensively investigating risks in animal breeding management, implementation of prevention and control systems, disinfection and source elimination, disease monitoring, and animal transportation, establishing a problem list, clarifying rectification time limits, and assigning special personnel to follow up and supervise, ensuring that all kinds of risk hidden dangers were rectified in a timely manner. Strengthen disinfection and source elimination work, purify the animal breeding production environment. On-site guidance for breeding entities to scientifically carry out disinfection work, explaining the ratio of disinfectants, disinfection procedures, key area disinfection points, and urging breeding farms (households) to regularly carry out comprehensive disinfection of breeding pens, activity areas, transportation vehicles, and feeding equipment. For key sites such as livestock and poultry trading markets and slaughterhouses, increase the frequency of disinfection, implement entry disinfection and full-process supervision measures, effectively purify the animal breeding and circulation environment, and minimize the risk of disease transmission. Strengthen prevention and control publicity and guidance, enhance the ability of collective prevention and control. Through household explanations, distribution of publicity materials, on-site Q&A, and other ways, the spring animal disease prevention and control knowledge, compulsory immunization policy, daily care points of livestock and poultry, animal disease identification, and emergency disposal were popularized among breeding entities and the public, guiding everyone to establish a scientific prevention awareness, creating a good prevention atmosphere in which the whole society participates and jointly manages.
