Call for new wildlife trade rules
Current
regulations are inadequate to stop imports of pets and livestock from
spreading lethal diseases, say international scientists.
A new global body is needed to regulate wildlife trade in light of threats such as Sars and bird flu, they say.
The call comes from the scientific steering committee of the non governmental organisation, Diversitas.
The panel will discuss the matter at an open science conference to be held in Mexico on November 9-12.
Dr
Peter Daszak, a member of the scientific steering committee of the
Paris-based group, said there needed to be better analysis of animal
species being moved around the world.
While some species such as
parrots are subject to quarantine regulations, this is not the case for
other animals, such as reptiles and amphibians, he said.
“It is
clear that the trade in wildlife is a huge source of disease
emergence,” he told the BBC News website. “Nobody is out there
monitoring these things.”
Economic costs
Dr Daszak, executive
director of the Consortium for Conservation Medicine at the Wildife
Trust, New York, said that techniques are available to screen animals
for emerging viruses.
Although it would not be practical to screen
all wildlife imports and exports, random tests on a selected number of
shipments would give a global picture of how diseases might be being
spread around the world, he explained.
“We need to move proactively and deal with the threat before diseases emerge,” he said.
As
well as the cost to human health, Diversitas, the international
programme of biodiversity science, funded by Unesco, will also consider
the economic impact of emerging infectious diseases, such as Sars and
bird flu.
Dr Daszak, part of the scientific team that connected
Asian bats in China with Sars, says the virus, which took 700 lives,
cost over $50 billion to the global economy in 2003, emerging from a
trade in wildlife for food.
“The economic impact of bird flu is likely to exceed this, especially if we get person-to-person transmission,” he said.
“It
is likely to cost us many hundreds of millions of dollars under current
estimates, and will be incredibly costly in terms of loss of human
life.”
