The purification process being considered
is to require
shellfish to be stored in freshwater for a period before
it is allowed to be sold or to be consumed.
I understand
that is the basis of what is
is known as the 'de-puration
process'.
DR. CHIU : Sir, I do not think the Secretary for Health
and Welfare has answered the second and third parts of my
supplementary question which are: What are the results in
general and how often are these tests conducted?
SECRETARY FOR HEALTH AND WELFARE : Sir, I do not have the
details, I must confess, of the frequency of tests. But I
will try and find out the information and write to
Dr. CHIU. (See Annex I)
PROF. POON Sir, is the artificial purification method
effective enough to remove most of the harmful substances
accumulated in the shellfish? If not, then would the
public be misled to believe that the so-called purified
shellfish is safe to consume?
