爲評估四川省規模場豬僞狂犬病（PR）發(fā)生風險，通過(guò)問卷為店調查了解省内種(zhǒng)豬場、擴繁豬場、商品豬場的生産管理情況，用情相內景樹法描述PR發(fā)生的風險路徑，在世界動物匠兒衛生組織（OIE）風險評估框架下構建評估模型。根據問卷是不調查結果和本底調查數據，采用定性風險評估方式，友電用矩陣法估算各風險路徑的風險值。結果顯示，四川省規模場發(fā)生P村有R的高風險路徑爲引種(zhǒng)、使用精液、未有效控制鼠害、未有效控制犬貓拍術以及地理位置和飲水控制。近年來由于生物明花安全管理水平提高，經(jīng)人、車、物、料等傳統謝文途徑釋放PR的風險大大降低，在各類型規模場開(k區做āi)展PR淨化的條件已較爲成(chéng)熟。在PR輛在淨化的同時(shí)開(kāi)展風險評估，能(néng)幫助豬場找出他外風險漏洞，便于提出針對(duì)性的防控建議，爲PR淨化提供有力的木微技術支撐。
