Avian influenza (AI) is a disease of concern for the poultry industry. In its highly pathogenic form, AI viruses (AIVs) can cause a high morbidity and case fatality rate as well as severe economic consequences. Low pathogenic AIVs (LPAIVs), in contrast, only cause localized infections in the respiratory and gastrointestinal tracts of affected birds. Although there is apparently sufficient scientific evidence documenting the absence of LPAIV in poultry meat, several countries still place restrictions for international trade of poultry meat on LPAIV-infected countries. These restrictions are extremely trade disruptive and entail significant losses to the poultry industry. This article presents a quantitative approach to assess the probability of LPAIV presence in chicken meat and provides a model that can be tailored to reflect the epidemiology of LPAIV and surveillance systems in different countries. Results show that the probability of introducing LPAIV through chicken meat imports is insignificant.
禽流感(AI)是家禽业关注的一种疾病。高致病性禽流感病毒(AIV)可导致高发病率和病死率以及严重的经济后果。相比之下,低致病性AIV(LPAIV)仅在受感染禽类的呼吸道和胃肠道引起局部感染。尽管显然有足够的科学证据证明禽肉中不存在LPAIV,但仍有几个国家对来自LPAIV感染国家的禽肉国际贸易实施限制。这些限制对贸易极具破坏性,给家禽业带来重大损失。本文提出了一种定量方法来评估鸡肉中存在LPAIV的概率,并提供了一个可定制的模型,以反映不同国家LPAIV的流行病学和监测系统。结果表明,通过进口鸡肉引入LPAIV的概率微乎其微。
