Xuhui closed last year without a case
Analysis of Liu Peihong, epidemiological surveys of the health sector, most H7N9 avian influenza exposure history or history of exposure to poultry. From the agricultural sector in some cases exposure to live poultry markets and environments, has H7N9 avian flu virus has been detected. Although the poultry in the city link H7N9 avian flu virus was detected there is no, but the Spring Festival is coming, a large number of exotic poultry into the city, increased the difficulty of prevention and control of avian influenza in the city. "Live poultry market is still avian influenza prevention and control in high risk areas. From last year's prevention and control experience, closure of markets is a very effective prevention and control measures. ”
"On April 6 last year, the city's all live bird market closed, after an incubation period of one week apart that is, full, there would be no new human infections in Shanghai H7N9 avian flu cases. Xuhui district, since last year after closing live bird markets, opening live poultry trading has not to date, the district has so far found no cases of human infection H7N9 avian influenza. "Liu Peihong said further analysis.
Cold fresh chicken taste does not transport live chickens
Urban population is highly concentrated in Shanghai, a large number of poultry imported from nearby. At the same time, farmers market population density, mobility, is an important medium of avian influenza and other diseases to spread, viruses exist, and land of the loops, easily causing viral recombination and mutation. Beijing starting from 2006 the permanent closing live bird markets, instead of the "poultry butcher, white poultry market" System.
The scientific experiments show that, "chilled chicken" at 0 ° c ~4 ° c in the cold chain can inhibit microbial growth and reproduction on the one hand, on the one hand but also by oxidation acid freshness control between 20%~30% of chicken, taste and taste do not transport live chickens. At present, the municipal Commerce Commission 2 chilled poultry slaughterhouses, 2 frozen poultry distribution centers and 50 chilled poultry retail trade-building circulation of chilled poultry safety information tracking system.
To this end, Liu Peihong believes that Shanghai already have permanent bases for closing live bird markets conditions, recommendations should be permanently shut down live poultry trading markets as soon as possible.

专家建议永久关闭活禽市场
晨报记者 谢克伟
在上海即将实施季节性关闭活禽交易市场的前夕，上海市动物疫病预防控制中心主任、研究员、预防兽医学博士刘佩红昨天在接受记者采访时认为，上海已具备永久关闭活禽市场的基础条件，应永久关闭活禽交易市场。
徐汇去年关闭至今无病例
刘佩红分析，卫生部门的流行病学调查显示，大多数H7N9禽流感病例有禽类暴露史或接触史。农业部门从部分病例接触的活禽市场和环境中，也已检测到H7N9禽流感病毒。虽然本市家禽养殖环节目前还没有检测到H7N9禽流感病毒，但春节即将来临，大批外来家禽进入本市，增加了全市禽流感防控的难度。“活禽市场仍然是禽流感防控的高风险区域。从去年的防控经验看，关闭市场是一项十分有效的防控措施。”
“去年4月6日，全市所有活禽市场关闭，在相隔一周也就是满一个潜伏期后，上海就没有新发人感染H7N9禽流感的病例。徐汇区自去年关闭活禽交易市场后，到目前为止一直未开放活禽交易，该区至今未发现人感染H7N9禽流感病例。”刘佩红进一步分析称。
冷鲜鸡口味不输活杀鸡
上海城市人口高度集中，大量的家禽从周边省区输入。同时，农贸市场人口密集、流动性大，是禽流感等疫病传播的重要媒介，也是病毒存在和循环之地，极易造成病毒的重组和变异。北京从2006年开始永久关闭活禽交易市场，取而代之的是“禽类定点屠宰，白条禽上市”制度。
有关科学实验表明，“冷鲜鸡”在0℃～4℃的冷链过程中一方面可抑制微生物的生长和繁殖，另一方面又能通过氧化排酸让鸡肉的鲜度值能控制在20%～30%之间，口感和口味不输活杀鸡。目前，市商务委将在2家冷鲜禽屠宰场、2家冷鲜禽配送中心和50家冷鲜禽零售交易点建设冷鲜禽流通安全信息追溯系统。
为此，刘佩红认为，上海已具备永久关闭活禽市场的基础条件，建议应尽早永久关闭活禽交易市场。
