    食品伙伴网讯   据世界动物卫生组织（OIE）消息，8月14日墨西哥农业、畜牧业、农村发展、渔业与林业部向OIE紧急报告称，7月24日锡那罗亚州（Sinaloa）的1家农场发生H5N2亚型低致病性禽流感。

    本次疫情属亚临床感染，有433093只家禽受影响，染病数量不详，没有死亡病例。诊断性质为实验室检验。感染来源尚不清楚。这是锡那罗亚州首次发生低致病性禽流感（墨西哥境内其他地区史上曾发生过该病）。

    Following the epidemiological surveillance activities carried out by the Veterinary Services of Mexico, avian influenza subtype H5N2 has been identified ; the intravenous pathogenicity test revealed that it corresponds to a low pathogenic avian influenza virus. The virus was isolated in a commercial farm of laying hens in the State of Sinaloa. The corresponding epidemiological investigation was initiated, including sampling in 4 industrial poultry farms and in 33 backyard poultry farms located in the 10-km zone around the outbreak, with a total of 720 samples of blood serum and tracheal and cloacal swabs, without detecting evidence of virus circulation. The production unit has been quarantined and a sanitary barrier has been set up. A humanely slaughter of birds programme will be launched even though it is a virus of low pathogenicity.
