- Hello Jeff - I like the way we hear about,"small
chance" of infection and then a decision to be made whether or not
to recall the products. I wonder if those experts who will evaluate the
blood would be in favor of not recalling the product if their loved ones
were going to receive the blood?

- Japan: Hepatitis B Virus Contamination in 37 Units of
Donated Blood -------------------------------------------------------------------
-
- Among 6400 units of blood for transfusion the government
ordered the Japan Red Cross Society to test, 37 were found to be contaminated
with hepatitis B virus (HBV), sources said on Sat 13 Sep 2003. According
to the sources, the 37 blood units probably have been used. The Health,
Labor and Welfare Ministry told the society to immediately test for HBV
those who received the contaminated blood. The Ministry said blood products
made from the HBV-tainted blood went through a virus inactivation process,
and there was "a very small chance of infection" among those
who received the products. The ministry will decide whether to recall the
products after experts evaluate the risks.
-
- The ministry has ordered the Society to investigate about
6400 units of blood that may have been contaminated with hepatitis or other
viruses and as shipped for use in transfusions during the past 13 months.
In response, he society has so far tested 293 units of blood for HBV. Further
cases of contamination may yet be found in future tests, the Ministry said.
-
- According to the Ministry, there have been no reports
of people becoming infected with HBV after receiving the contaminated blood.
No blood has been reported to be contaminated with hepatitis C virus or
human immunodeficiency virus.

- Japan: Patient Contracted Hepatitis B Virus from Blood
Donation in 2001 -----------------------------------------------------------------------
-
- A man in his 50s became infected with hepatitis B virus
(HBV) after he received tainted blood that had cleared a screening test,
it was learned on Sat 13 Sep 2003. The Ministry ordered the Red Cross Society
and Nihon Pharmaceutical Co. to recall 56 000 units of blood products made
from blood of the donor concerned. According to the Society, the infected
man received the red blood cells of four donors in February 2001 after
bleeding due to an alimentary disease. He tested positive for HBV in June.
-
- The Society was informed of the infection in August [2001].
It checked the reserved blood samples of the four donors and found one
of them contained HBV. The virus was not detected in earlier tests. The
society and Nihon Pharmaceutical had used the contaminated blood to manufacture
blood products.
-
- The Society reported the case to the ministry on Fri
[12 Sep 2003?}. The ministry ordered the society to recall sold products,
suspend shipments and test those who received the products for HBV. Up
to 56 000 products must be recalled as the products are mass-produced from
a number of donors' blood .
-
- These products are in addition to the 6400 blood units
the Society is testing in its ongoing investigation. In July, the society
said 6419 blood units that may have been contaminated with viruses were
supplied to medical institutions nationwide in the 13 months from June
last year. At that time, the society said only 13 of the products could
be recalled as the rest already had been used. Of those 13, 11 were contaminated
with HBV and two were contaminated with HCV. The Society added that the
contaminated units may have slipped through the screening process as conventional
technology cannot ascertain contamination if the donor has only recently
become infected.
