Humans blamed for animal-related disease
Humans blamed for animal-related disease

Humans are to blame for the recent spread of many life-
threatening diseases that are related to animals, including
Bovine Spongiform Encephalophathy (BSE) or mad cow disease, avian
influenza, also known as bird flu, and dengue hemorrhagic fever,
experts say.
Mad cow disease and avian influenza are found among cows and
poultry and only infect animals. However, the viruses that cause
the diseases have mutated, resulting in the diseases being
transmitted to humans.
The head of the Indonesian Veterinary Association (PDHI) in
East Java, C.A. Nidhom, told The Jakarta Post on Wednesday the
mutated virus was a result of the forced change in the ecosystem
caused by humans.
Citing an example, he said cows that normally fed on grass had
been fed processed animal feed such as bone meal (the ground
bones of cattle) and other food originating from the cows
themselves to speed up their growth.
This "cannibalism" has caused BSE disease in cows, which was
later transmitted to humans. Indonesian cows are not infected by
BSE because they mostly feed on grass, Nidhom said.
"Right now, people only care about how to reach production
targets. They forget about the biological aspect of the animals,"
he said.
He said the farming concept in Indonesia relied too much on
efficiency and economic aspects. This can be illustrated by many
poultry farms that breed ducks and chickens in one pen.
"They do not know that ducks can carry avian influenza without
being infected and if chickens are in close contact with the
disease-carrier ducks, they will get infected," he added.
Hormone injections or growth enhancing additives given to
chickens to fatten them and make them grow larger will give a
larger profit to the farmers. These kind of steps are believed to
be the cause of the mutated virus, Nidhom said.
Director of the Veterinary Community at the Ministry of
Agriculture, Bachtiar Moerad, expressed the same concern.
"People are too greedy right now, they will do anything for
their own benefit such as feeding cows or chickens unnatural
feed," said Bachtiar.
However, Bachtiar also said that the virus mutation might be
caused by the changes in living patterns and also physical
changes in the world.
"Scientists predict that new diseases will emerge with the
progress of time," he said.
The International Herald Tribune reported a study that found a
new form of mad cow disease in Italy.
Scientists believe that it may be the cause of some cases of a
human brain-wasting disease known as Creutzfeldt-Jakob Disease
(CJD), which is the human form of mad cow disease.
Last year, a total of 153 cases of CJD cases were reported
worldwide. Of these, 143 had occurred in the UK.
Meanwhile, Asia's bird flu death toll has risen to 21.
In Indonesia, dengue fever had killed 91 people as of Tuesday.
