自1994年以来，从美国东北部的活禽零售市场分离到低致病性禽流感病毒(AIV)H7N2。这项研究调查了纽约和新泽西的LBM供应商。2001年，对9个州的185家供应商进行了鸡蛋胚胎病毒分离(VI)，以检测AIV的存在。未分离到H7、H5病毒。此外，两个州的104个生产场所的H7和H5禽流感病毒血清学呈阴性。通过问卷调查获得了12个州191个房舍的管理做法信息。调查结果表明，供应商场所目前的生物安全做法可以改进，特别是在鸟类活动方面。这项研究支持这样一种假设，即H7N2型禽流感病毒主要保持在低成本管理制度内，如果从供应商重新引入，很可能是以非常低的水平重新引入，或者来自不在本研究范围内的供应商。
Low pathogenicity avian influenza virus (AIV) H7N2 has been isolated since 1994 from retail live-bird markets (LBMs) in the northeastern United States. This study examines the suppliers to the LBMs in New York and New Jersey. In 2001, 185 supplier premises in nine states were surveyed for the presence of AIV by virus isolation (VI) in embryonating chicken eggs. No H7 or H5 virus was isolated. In addition, 104 producer premises in two states were serologically negative for H7 and H5 AIV. Information on management practices was obtained via questionnaire for 191 premises in 12 states. The survey results suggest that current biosecurity practices at supplier premises could be improved, especially regarding movement of birds. The study supports the hypothesis that H7N2 AIV is primarily maintained within the LBMs and, if reintroduction from suppliers is occurring, it is likely retintroduced at a very low level or from suppliers not included in this study.
