Scientists last month warned that Bovine Spongiform Encephalopathy
(BSE), or Mad Cow Disease, has joined AIDS as a major health
challenge facing the world. A conference organised by the
World Health Organisation (WHO) and the United Nations Food and
Agriculture Organisation (FAO) concluded with a call for governments
to strongly consider testing for BSE in cattle used
for human consumption and imposing a worldwide ban on meat and
bonemeal cattle feed (MBM).
BSE and its human equivalent, variant Creutzfeldt Jacobs Disease
(vCJD) cause a fatal wasting away of the brain. The infectious
agent is believed to be a mis-shaped prion protein, causing the
development of lesions in the brain. There is no cure for vCJD,
although Dr John Collinge, director of the new prion unit at Imperial
College in London believes that in the next five years we
may be able to produce something that .... provides a treatment
for this disease.
The disease has already claimed 102, mainly young victims in
Britain, three in France and one in Ireland. There are suspected
cases in Hungary, Hong Kong and elsewhere. The charity, Wellcome
Trust, estimates there will be about a quarter of a million cases
of vCJD in Britain by the year 2040.
Samuel Jutzi, director of the animal production and health
division of the FAO, warned the conference of the possibility
that BSE could spread far outside the European Union. He said
Its safe to say that eastern Europe may have imported
sizeable amounts of risk given the sheer trade figures we have.
Another area may indeed be the Near and Middle East. A few
days later the first country in eastern Europethe Czech
Republicreported a case of BSE. Since the Czech government
only banned the use of high-risk cattle by-products for human
consumption in January 2000, it is clearly possible vCJD cases
will start to appear there.
BSE was first recognised in Britain in the early 1980s. There
have been 180,900 cases of BSE in Britain and officially there
are still 1,500 cases a year. Changes in the rendering industry,
and the increased use of MBM in cattle feed, are thought to have
increased the spread of the disease.
In 1988, some time after MBM was suspected of spreading BSE,
the Conservative government of Margaret Thatcher banned its use
in feed for ruminants such as cattle, sheep and goats in Britain.
However, the government allowed the export of MBM until 1996 when
it finally admitted a link between BSE and vCJD. Records show
that over one million tonnes of MBM were exported from Britain
to Asia between 1988 and 1996. According to Keith Meldrum, the
governments chief veterinary scientist at the time, it was
up to importing countries to stop accepting our exports.
For 11 years Britain exported the remains of BSE-infected cows
to more than 80 countries where it was often repackaged and re-exported.
Where governments around the world have taken action against
the BSE threatand most claiming they are BSE free
have notthe policies have been limited, uncoordinated and
often unenforced. Protecting national business and agricultural
interests by governments, industry and trade unions has been the
major factor. The search for a suitable test and cure has therefore
been delayed. The tests that are currently available are not sensitive
enough to detect the small amounts of prions circulating in the
blood (although two research groups are now developing tests)
and it is still only possible to carry out tests on brain material
where the prion is most concentrated. In Switzerland, where the
first case of BSE occurred in 1990, all cattle are now
tested for BSE after slaughter using a new rapid testing method
on the brain. The older method appeared to show a dramatic decline
in the disease in 1998, but with the introduction of the new method
the following year there was a four-fold increase in cases of
BSE recorded. This points to massive underreporting in every other
country, and Britain in particular.
On July 1, new EU BSE Regulations came into force due to the
spread of the disease to Ireland, Portugal, Switzerland, France,
Germany, Spain, Netherlands, Belgium, Italy, Liechenstein and
Luxemburg. Many of these countries had denied they had a BSE problem.
Until tests proved otherwise, the German government declared the
country to be BSE free. There have been 90 cases so far, 77 of
them this year. In Spain, 48 cases has been detectedall
but two of them this year.
The new regulations say that slaughterhouses must carry out
a BSE test on all cattle over the age of 30 months that are used
for human consumption and sick animals over 24 months. Some random
tests of healthy cattle over 24 months must also be carried out.
In Britain the government is only required to randomly test 50,000
cattle over the age of 30 months. The British Food Safety Agency
(FSA) claim there is no need for any testing in Britain because
of the national ban on the sale of beef from cattle over the age
of 30 months. However, they will carry out the random testing
in order to provide epidemiological evidence. The Agency said,
We support the right of other countries to test all cattle
over 24 months, but in UK conditions we do not believe that testing
under 30 months would provide additional public health protection.
The FSA press release states that in the UK, testing has
until now been carried out primarily among animals aged over 30
months, but it does not say that the numbers tested were
only 171 between January and May this year out of the European
total of 3.5 million.
Professor Hugh Pennington, professor of bacteriology at the
University of Aberdeen, condemned such complacency and omission.
Pennington, who chaired the inquiry into the E.coli food poisoning
outbreak in Lanarkshire, Scotland in 1996, said he feared new
food disasters on a similar scale to BSE... Nobody knows when
the next food-borne bugs will arrive but they are evolving right
now. I fear that without fundamental reform in the way policy
makers get and use scientific advice there will be big trouble
ahead. He continued that the Labour government is too secretive
and criticised the link between science and industry.
Professor Richard Lacey, who was persecuted for his criticisms
during the BSE crisis, says, Blair continues to deceive.
There are an unknown number of animals infected and people are
still eating contaminated beef.
These criticisms of the Labour government are borne out by
the foot and mouth epidemic that has resulted in the infection
of 1,800 farms and the slaughter of 3.5 million animals in the
UK. In 1997 the Labour governments Spongiform Encephalopathy
Advisory Committee warned against feeding pigs waste meat. Jack
Cunningham, the Agriculture Minister said at the time, processing
certain types of waste containing porcine material and feeding
it as swill to pigs will have to end. But the use of catering
waste as swill continued. The current epidemic of foot and mouth
disease is believed to have started from this source.
More than 90 burial sites were used to dispose of all the cattle
slaughtered due to foot and mouth disease. The burials included
cattle over five years old, which should have been incinerated
under the governments own BSE regulations. The government
has now ordered the carcasses to be dug up to protect water supplies
from infection with the BSE agenta rather belated attempt
because most body fluids will have leaked out after two months.
Such practices underscore that the BSE Inquiry set up by Labour
two years ago in response to public outcry was an entirely cosmetic
exercise. Only last month European veterinary inspectors published
a report of their investigation into the British meat industry.
It said processed meat products gives rise to serious concern
and checks on raw materials used for food were weak or even
non-existent.
