Text / Yangcheng Evening News reporter Huang Xiaoqing
Last June, the clever implementation of live poultry "centralized slaughtering, unified distribution, fresh listing" pilot project, seven farmers market ban live poultry, however, by the end of December last year, Gaoming fresh chicken market is still detected avian influenza virus, After the sale of live poultry and established a restricted zone, part of the external market environment, the number of smear-positive samples detected in restricted zones also more than non-restricted zone market.
January 7, 2016, Gao CDC responded that the responsible person, fresh chicken is not not carry the avian flu virus, centralized slaughtering, fresh listing of the principal is to reduce human exposure to live poultry, to reduce the virus in vivo between animal flow, reduce pollution market. "Is clear that within the fresh chicken market, risk of human infection with bird flu virus is far lower than the sale of live poultry in the market." The official said. It is reported that on January 6, clever bird flu prevention and control work has already held meetings, require departments to jointly implement the bird flu prevention and control measures.
Multi duties avian influenza virus detected in environmental samples
Last June 1, Gaoming implementation of live poultry "centralized slaughtering, unified distribution, fresh listing" pilot work, the central city seven farmers' markets, namely Dutch city market, the cultural market, Xinghua market, Dongsheng market, Wuyang market , the official when Future markets and Lotus market, prohibit live poultry trading, started selling fresh chicken. This is to reduce the chance of contact with the public and live poultry, effectively cut off the transmission of poultry diseases and zoonoses in circulation, prevention and control of avian influenza at the source.
November Month - December 28, Gaoming District CDC collected more than birds outside the business market in environmental samples carried avian influenza virus nucleic acid testing, were detected 38 bird flu nucleic acid positive.
Avian influenza viruses HXNX type, in which there are 15 H subtypes, type currently do not infect humans mainly H5, H7 and H9. In the 38 positive samples, H7 nucleic acid positive 6 parts, 5 parts of the market where Schmidt, 1 Xi'an market; H5 nucleic acid positive 2 parts, all from rich Gulf market; H9 nucleic acid positive 36, which comes from 21 parts of fresh chicken market, from live bird markets in 15 parts. That is, after the establishment of restricted zones prohibit live poultry trade restriction zone portion of the outer fresh chicken market environment remains smear samples detected avian influenza virus, and the number of positive samples than non-restricted area of live bird markets.
Why fresh chicken market is still bird flu virus
Above monitoring results show that the avian influenza virus market restricted zone pollution worse than non-restricted zone. why will this happen? 7, Gaoming CDC director Tony Chen had to respond to this.
Tony Chen said the first clear is, the implementation of live poultry "centralized slaughtering, unified distribution, fresh listing", the risk of people in the market of fresh chicken infected with bird flu is much lower than the live bird market. "Ban live poultry, selling fresh chickens, cross-cutting within the market less infection feathers, droppings and chickens between bird flu virus will be a lot less pollution, with neighbors of the reach of live birds, poultry infection low risk nature of influenza. "
The fresh chicken market is still positive for the detection of avian influenza, Tony Chen believes that the current market on clever chicken from across the country, these chickens to bird flu virus mutation provides recombinant sources, combined with the spread of the avian influenza virus and is very fast, extremely chickens easy to cross contamination, chickens infected with bird flu virus after being slaughtered, the virus may still be carried to the fresh chicken market.
In addition, Tony Chen stressed that "at present not yet reached the numerical comparison of time", just look at 60 samples within a month to make a final conclusion is unscientific, must go through a large number of numerical analysis over a long enough period of time, Gaoming District CDC We will continue to take samples for testing.
However, he also said that disease control departments will urge the strengthening of centralized storage management slaughterhouse chickens, well disinfection, to enhance awareness of disease prevention and control personnel, reducing avian influenza virus infection centralized slaughtering stages.
High risk clever around the Spring Festival has strengthened the prevention and control
In previous years, the smart district of avian influenza virus nucleic acid positive number since the beginning of the annual rise in November, December - April the following year continued to peak. In other words, it is currently in the high incidence of bird flu. This reporter has learned, the Group assessed that a higher risk of human infection before and after the Spring Festival, Gaoming District, sporadic cases of H7N9 bird flu, does not rule out the possibility of other subtypes of avian influenza.
In this regard, on January 6, Gaoming District held meetings bird flu prevention and control work, requiring departments to jointly implement various prevention and control measures.
Gaoming District Health and Family Planning Bureau, responsible person, has detected H7 positive arrangements Xi'an market closed three days, emptied herds suspend live poultry trade and markets, particularly waders stalls cleaned and disinfected; by the district disease control After the center carry out environmental monitoring of qualified foreign markets again, the live poultry market before resuming operations; day after resumption of the implementation of a cleaning and disinfection, a clean-up week, closed on January 1 and zero population live poultry system. As Schmidt banned live bird markets, according to the relevant scheme, which closed without temporary measures to implement; however, it has been called for the strengthening of market stalls and waders cleaning and disinfection work, and strictly implement a disinfection cleaning day, a week, cleaning.
7 morning, the reporter went to the Wah market, the market has not found a live animal inside and outside; but in the market, not far from the Dutch city of Xinghua market, the reporter found that the irregularities surrounding the sale of live poultry stalls in the presence of flow phenomena, and vehicles carrying live chickens exchanges. This regard, the official said, on Sizai live poultry, live birds and other irregular operations will be zero tolerance for violations, we found a deal with a resolutely ban the flow of poultry vendors.
In addition, Gaoming Deputy Secretary of Health and Family Planning Bureau 李梅玲 presented at the meeting on the 6th, we will focus on Gaoming Market Authority purchase inspection, certificate and invoice work, to prevent birds from entering the market within Sizai fish in troubled waters. At the same time, strengthen market management and law enforcement surrounding mobile vendors.
Related departments:
Buy fresh chicken and cut process
Risk of infection is minimal
Reporters consult found bird flu research professor for 20 years, South China Agricultural University, BI Ying Zuo earlier interview with the media have said that from the virus itself situation, chilled and risk actually live poultry is about the same, frozen virus The case really can survive a long time. But if you eat chilled, then the risk will be concentrated at slaughter.
Tony Chen said that the chance of fresh chickens carrying the virus cause of human infection with bird flu virus is minimal, and the bird flu virus was heated for 30 minutes at 65 ℃ or under boiling state can be inactivated more than two minutes. In other words, the probability of the process of buying and cut infection is minimal, and the high temperature cooked chicken does not contain viruses.
