From February 20 to 21, Hebi City in Henan Province collaborated with the Provincial Epidemic Control Center to collect samples for African swine fever risk monitoring at four types of sites including pig slaughterhouses, decontamination centers, harmless treatment plants, and farmers' markets in Jun County and Qi County. A total of 91 samples were analyzed, and the city also discussed the prevention and control of major animal diseases with the company and technical personnel. This on-site sampling is crucial for accurately assessing the African swine fever situation, identifying hidden dangers, and guiding prevention and control efforts.
