目的：为评价鲜禽产品供应对降低广州市集贸市场禽流感病毒（AIV）环境污染的效果，随机抽取广州市40个集贸市场，其中活禽20个，鲜禽产品20个，于2014年7月至2015年4月每4个月对80个家禽档进行环境监测。从每个家禽档的不同部位采集4份涂片样本进行禽流感病毒核酸检测。结果：40个活禽档95.0%（38/40）的活禽过夜饲养，25.0%（10/40）的活禽每天消毒，95.0%（38/40）的活禽每周清扫，95.0%（38/40）的活禽每月休市1天。在40个新鲜家禽产品摊位中，20.0%（8/40）的摊位每天进行消毒，90.0%（36/40）的摊位每周进行清洁，96.0%（38/40）的摊位曾经出售活禽市场的屠宰家禽。活禽市场AIV阳性率为40.4%（252/623），高于鲜禽产品市场活禽市场中H9亚型病毒阳性率为28.6%（178/623），与对照组相比差异有显著性（χ 2 =8.85，P=0.003）。高于鲜禽产品市场（16.2%，99/610），差异有显著性（χ 2 =26.95，P
OBJECTIVE: To evaluate the effect of supply of fresh poultry products on reducing environment contamination of avian influenza virus (AIV) in markets in Guangzhou.METHODS: A total of 40 markets, including 20 selling alive poultry and 20 selling fresh poultry products, were selected randomly in Guangzhou to conduct environment surveillance in 80 poultry stalls every 4 months from July 2014 to April 2015. Four smear samples were collected from different sites of each poultry stall to detect nucleic acid of AIV. The positive samples were further detected for AIV subtype H5, H7 and H9 nucleic acids.RESULTS: Among 40 alive poultry stalls, 95.0% (38/40) kept alive poultry overnight, 25.0% (10/40) were disinfected daily, 95.0% (38/40) were cleaned up weekly, 95.0% (38/40) were closed for one day every month. Among 40 fresh poultry product stalls, 20.0% (8/40) were disinfected daily, 90.0% (36/40) were cleaned up weekly, and 96.0% (38/40) ever sold dressed poultry from alive poultry markets. The positive rate of AIV in alive poultry markets was 40.4% (252/623), higher than that in fresh poultry product markets (32.3%, 197/610), the difference was significant (chi(2)=8.85, P=0.003), and the positive rate of subtype H9 virus in alive poultry markets was 28.6% (178/623), higher than that in fresh poultry product markets (16.2%, 99/610), the difference was significant (chi(2)=26.95, P
