4, Richard aspects of smuggling of chicken manure sole source of the vaccine

Hong Kong farms have been 6 years found no bird flu so far this summer, coupled with the global outbreak of bird flu cases lower than last year, the Lau Fau Shan Ha Tsuen, Yuen Long farm model of the outbreak of bird flu, has become more intriguing. Head of the Department of Microbiology of the University of Hong Kong Yuen Kwok-yung said that the farm biosecurity measures have been very tight, do not rule out the virus with the objects in the farms go, destroyed farms, bio-security measures. This newspaper has learned that the Government will follow the chicken farm into smuggling, migratory birds droppings, workers on the sticky soles  virus and vaccine failure, and so to trace the source of the drug broadcast, and the smuggling of chickens into the outbreak of bird flu risk will be one of the priorities of the investigation.

Last year, bird flu outbreaks around the world, as far away as Britain, Russia, Hungary, Africa and Nigeria has not been spared, at least 16 the number of the outbreak. But so far this summer, moderated the epidemic, bird flu broke out around the 10 cases not enough (see Figure), mainly in Asia. Hong Kong has always been a high degree of bio-security model farms in a sudden move, it is difficult to understand.

Yuen Kwok-yung Yuen Long farm do not want to comment on the reasons for the outbreak of the bird, but he said that the farm biosecurity measures are very tight, the virus does not easily imported. Unless there are objects with the virus enter and leave the farm, including the transportation means of transport workers sticky soles  virus or droppings of migratory birds, and whether there will be mixed with the smuggling of chicken farms, it is likely that the virus outbreak on a farm.

Comprehensive views of the parties that because of a few more than 10 days is the Chinese people have always attached great importance to the winter, most people are willing to buy live chickens over the winter, did not rule out based on business incentives that will encourage the smuggling of chickens into the outbreak of bird flu risk factors.

Yuen Kwok-yung of the view that the vaccine failure and the outbreak of bird flu farms do not have any relations, foreign farm biosecurity measures are very strict, so foreign non-vaccinated birds. As long as farm biosecurity measures fully comply with the provisions of the farm operations to fully comply with regulations to deal with, even if the vaccine will not expire outbreak of bird flu.

Yuen Kwok-yung: vaccine failure is not surprising

He said Hong Kong had been detected in wild birds and chicken stalls in the market samples of the bird flu gene is H5NI, but the vaccine in Hong Kong in 2001, the use of H5N2, it is also not surprising that failure to start the vaccine. He suggested that the Government discuss with the mainland authorities in Hong Kong can follow the example of the use of the Mainland H5NI vaccine to prevent bird.
