在孟加拉国，活禽市场环境经常受到禽流感病毒的污染。商店一级的生物安保做法可能会增加环境污染的风险。我们试图确定哪些车间一级的生物安全做法与环境污染有关。我们调查了800家家禽店，以描述生物安全措施并收集环境样本。来自205家（26%）商店的样本对甲型流感病毒RNA呈阳性，108家（14%）对H9呈阳性，60家（8%）对H5呈阳性。屠宰家禽、过夜饲养家禽、无休息日营业、地板泥泞不平、将家禽放在地板上以及将病禽和健康家禽放在一起的商店更容易对甲型流感病毒呈阳性。报告的每月清洁似乎具有保护作用，但消毒做法与甲型流感病毒检测无关。屠宰、过夜饲养家禽、每周休息日、基础设施和消毒做法可以成为减少环境污染的干预措施的目标。
In Bangladesh, live bird market environments are frequently contaminated with avian influenza viruses. Shop-level biosecurity practices might increase risk for environmental contamination. We sought to determine which shop-level biosecurity practices were associated with environmental contamination. We surveyed 800 poultry shops to describe biosecurity practices and collect environmental samples. Samples from 205 (26%) shops were positive for influenza A viral RNA, 108 (14%) for H9, and 60 (8%) for H5. Shops that slaughtered poultry, kept poultry overnight, remained open without rest days, had uneven muddy floors, held poultry on the floor, and housed sick and healthy poultry together were more frequently positive for influenza A viruses. Reported monthly cleaning seemed protective, but disinfection practices were not otherwise associated with influenza A virus detection. Slaughtering, keeping poultry overnight, weekly rest days, infrastructure, and disinfection practices could be targets for interventions to reduce environmental contamination.
