Implementation Plan for the Risk Assessment of Highly Pathogenic Avian Influenza in Dairy Cattle

In accordance with the requirements of the Ministry of Agriculture and Rural Affairs’ Bureau of Animal Husbandry and Veterinary Medicine’s “Notice on Effectively Preventing the Introduction of Avian Influenza from Abroad,” this plan is formulated to ensure the successful conduct of the 2025 risk assessment on highly pathogenic avian influenza in dairy cattle. 
 

I. Purpose of the Survey 
 

Assess the risk of highly pathogenic avian influenza infection in dairy cows and provide recommendations for measures to facilitate early detection and risk prevention of this disease. 
 

II. Scope of the Survey 
 

Inner Mongolia, Liaoning, Heilongjiang, Jiangsu, Shandong, Henan, Sichuan, Yunnan, Ningxia, and Xinjiang—provinces located along major migratory flyways for wild birds and with substantial dairy cattle farming—were selected as survey provinces. Within each province, key wild bird habitats, breeding grounds, and major stopover or wintering sites along bird migration routes were identified (with priority given to areas that have previously experienced outbreaks of avian influenza in wild birds). Targeted surveys were then conducted among 10 dairy farms of varying sizes in the counties and county-level cities surrounding these areas. 
 

III. Survey Content 
 

(1) Sample Collection. At the end of April and the end of November, two bulk-tank milk samples, each 10–20 mL, were collected from designated dairy farms. Concurrently, five milk samples (5–10 mL per sample) and five serum samples (1–3 mL per sample) were collected from cows exhibiting clinical abnormalities, including lactation disorders, fever, reduced feed intake, or nasal discharge. For cows without clinical abnormalities, five milk samples (5–10 mL per sample) and five serum samples (1–3 mL per sample) were collected randomly (see Appendix Table 4-1 for the sampling registration form). All samples were stored at −20°C. 
 

(2) Questionnaire survey. While collecting samples, complete the survey questionnaire to obtain information on dairy farm management practices, animal transportation, disease prevention and control, and contact with wild birds and other avian species; see Appendix Table 4-2 for details. 
 

IV. Organization and Implementation 
 

The China Animal Health and Epidemiology Center, in collaboration with the relevant provincial animal disease prevention and control agencies, will jointly implement this initiative. Each of these provincial agencies shall identify a list of designated dairy farms and designate contact persons, and by the end of April and November 2025, shall assist in completing sample collection. Once the samples are centrally collected, they will be either mailed to the Center or dispatched individually by the designated dairy farms. The China Animal Health and Epidemiology Center will be responsible for sample testing and result analysis, and, in light of developments in overseas epidemic situations and the needs of domestic risk assessments, will conduct on-site investigations as appropriate.

(1) Survey of the Current Epidemiological Situation of Major Avian Diseases in Intensively Farmed Areas 
 

In 13 provinces—Jiangsu, Anhui, Fujian, Jiangxi, Henan, Hubei, Hunan, Guangdong, Guangxi, Sichuan, Guizhou, Yunnan, and Ningxia—two representative prefecture-level wholesale live-poultry markets, six live-poultry retail markets, and six waterfowl farms (either open- or semi-open-range operations) were selected in each of the periods January–May and September–December for the collection of avian swab samples. Sample-collection registration forms (Appendices 5-1 and 5-2) were completed for all collected samples. Specifically, at each wholesale live-poultry market, 12 stalls were sampled, with 10 avian samples collected from each stall; at each live-poultry retail market, 6 stalls were sampled, with 5 avian samples collected from each stall; and at each waterfowl farm, 30 samples were collected, for a total of 600 samples. For provinces and municipalities where live-poultry markets are insufficient, sampling, testing, and survey analysis may be conducted at waterfowl farms instead.

(2) Investigation of Pathogen Transmission Risks at the Wild-Poultry and Domestic-Poultry Interface 
 

On the migratory routes of wild birds or in the vicinity of their habitats in six provinces—Heilongjiang, Jiangxi, Shandong, Hubei, Guangdong, and Qinghai—1 to 2 sampling sites shall be established based on geographic location and the abundance of wild bird populations. In accordance with the timing of wild bird migration, each sampling site shall collect no fewer than 100 swab or fecal samples from wild birds and complete the Sample Collection Registration Form (Appendix 5-3). If the number of available samples is insufficient, sampling may be conducted at open- or semi-open waterfowl farms for testing and investigative analysis. 
 

IV. Organization and Implementation 
 

The China Animal Health and Epidemiology Center is responsible for sample collection, testing, analysis, and report preparation. Animal disease prevention and control agencies in the relevant provinces assist with sample collection and result analysis, and suspected positive samples for Newcastle disease and other diseases are promptly submitted to the China Animal Health and Epidemiology Center for further confirmation.
