    Ministry of Agriculture in the submitted sample from Jiangsu and Zhejiang 5 copies of the H7N9 avian influenza positive samples detected
    Date :2013 -04-16 15:19 Author: Source: Information Office of the Ministry of Agriculture

      NEEDHAM Ministry of Agriculture office April 16, Jiangsu and Zhejiang animal disease prevention and control center detected 12 were suspected positive samples, and review by the National Avian Influenza Reference Laboratory, 5 were positive for H7N9 avian influenza which the feral pigeons samples from the Qinhuai District of Nanjing, Jiangsu Province, and 1 part chicken samples from the north of Zhejiang Huzhou City, Zhejiang Province, agricultural and sideline products wholesale center, 3 servings of chicken samples from Huzhou, Zhejiang Wuxing the dojo Township farmers market. Gene sequence analysis showed that all of the above isolates isolated from pigeons and April 4, H7N9 avian influenza virus strains are highly homologous.

      The Ministry of Agriculture has asked the Jiangsu and Zhejiang provinces to strictly do the work to deal with in accordance with the Ministry of Agriculture, Animal H7N9 avian flu emergency response guide (Trial) ". At the same time, requiring further expand the scope of monitoring of the H7N9 avian flu virus, and earnestly implement various prevention and control measures.

      Have not found another source to corroborate this one but it mentions ducks and chickens having LPAI H7N9 and also slightly different location of Anhui. It also states no birds were slaughtered or destroyed - so I am wondering if they were left in the market and sold for food? http://www.thepoultrysite.com/poultr...n-duck-samples
