Press Releases
SFH on avian influenza
Following is the transcript of remarks made by the Secretary for Food and
Health, Dr York Chow, at a media session after attending radio programmes this
morning (June 11):
Reporter: The latest discovery of bird flu last Saturday has exposed the
loophole in the Government's bio-security measures. What are you trying to do
now to prevent this from happening again?
Secretary for Food and Health: We have analysed the situation very closely since
last Saturday. The four levels of control in terms of bio-security and of avian
flu are in our poultry farms, in the border between the Mainland and Hong Kong,
the wholesale and retail markets. We have been doing a lot of inspection in our
local farms. We have sent our inspectors and veterinary specialists to the
Mainland to look at some of the affected farms destined for Hong Kong. So far,
we have not discovered any abnormality. The PCR tests for virus are also
negative. We also look at the wholesale market. We found that the poultry in the
market had shown no abnormality and the PCR tests are also negative. We also
screened through the tests from all the chickens passed through Man Kam To to
see whether there is any abnormality in the last few weeks. Again, we did not
find anything. The only abnormality we have detected is in the retail market.
The test for the retail market involved both the PCR test and egg inoculation
test. PCR test will give result within a short time and that's why we have
announced the result on Monday when the first batch of results came up. But
there will be more results coming from the egg inoculation tests from the retail
market later today. We hope that with those results coming out, we can have a
clearer picture of the extent of the problem. If we found any of these
additional tests showed positive results, we need to take relevant actions
immediately.
Reporter: Do you admit that smuggling of chickens remains a big problem for your
bureau?
Secretary for Food and Health: According to the record of the Hong Kong Customs,
we have discovered four incidents of smuggling. We have also actually been able
to confiscate all the chickens last year. The biggest amount we have confiscated
last year is almost up to 4,000. This is actually a sizeable smuggling exercise.
The most important thing when we come to counteract such activities is
information and intelligence. We hope that the trade would be more honest and
able to tell us about what they have received. Because most of the time we have
to rely on such information before we can mount any operation.
Reporter: How do you respond to criticisms that the bureau lacks political will
to cull all the chickens on Monday instead of allowing the retailers to sell the
chickens?
Secretary for Food and Health: It is not a political decision. According to our
guideline, if we find there is one retail site that has H5N virus avian
influenza, we will just cull (chickens in) that site. But if we have more than
one site, then we will have a suspicion that it would have spread. Then of
course we have more justifications to cull all the chickens. Up to last Monday,
there is only site that we have discovered to have H5 virus.
Reporter: (about the latest incident in Tseung Kwan O Hospital where data of
patients were dumped into landfill)
Secretary for Food and Health: It is regarding a doctor who has not disposed of
or put the relevant documents in the right place. I don't know the details. But
it is important for any health care workers that needed to handle patients'
documents involving confidentiality and privacy to lock the documents up and put
them in the right place. With the electronic health care system in the Hospital
Authority, there is no reason that it should keep a lot of hard copies. They
need to dispose of them in a proper way, either shredding them or giving them
back to the original department.
Reporter: A lot of people are concerned about whether one can get bird flu
through eating. Do you have any advice for these people?
Secretary for Food and Health: According to experts, so far all the patients of
avian flu did not contract the disease from eating chickens. Most of them
contract the disease by contacting sick chickens, in the process of slaughtering
sick chickens or in the presence of live sick chickens. All these are the
scientific evidence showing that chilled and frozen chicken meat, though they
might be contaminated with the virus, the risk of transmitting disease to humans
is very low.
Reporter: (about egg inoculation)
Secretary for Food and Health: The egg inoculation process takes some time, a
matter of three to seven days. Most of the virus can come out usually within
three or four days. If the amount of virus is low, it will come out in six to
seven days. Normally, our scientists will discard the egg after about a week,
depending on whether there is any significant change. It is a very accurate
test, considered as a benchmark test and gold standard test for H5N virus. But
unfortunately it is slow. The PCR is the test that we always rely on when we
suspect there is an H5 infection.
Reporter: Bird flu normally occurs in winter months, but this time it appears in
summer. So how concerned are you that there is a different strain?
Secretary for Food and Health: We have done a genetic sequencing of the virus.
It is the same as most of the dead birds we have discovered this winter. There
is no change in the genetic sequencing of the virus this time.
