African rats trained to sniff out landmines, detect tuberculosis in humans
Nairobi – Africa’s giant rats have
been trained to sniff out landmines and detect tuberculosis in humans, and soon
they could turn their superior noses to protecting other animals by finding
illegal wildlife trophies being smuggled out of African ports.
Kirsty Brebner,
whose organisation Endangered Wildlife Trust had the idea of putting rats to
work on the illegal wildlife trade, disclosed this on Friday in
Nairobi. She
said the U.S. financed project was still in its early stages, but the rats that
would be trained to scuttle over shipping containers in search of pangolin
scales were only born in October. Brebner said the aim was to prove by late
2017, that their powerful sense of smell could distinguish the illegally traded
items. She said the items would be detected, even if they were stashed in
coffee or other scent-masking substances in containers before they were loaded
onto ships for export.
“I firmly believe that we are going to be able to prove
that they can.
“They are clearly trainable, they have a strong sense of smell,
the eventual aim is to train rats to find ivory and rhino horns too,’’ she
said. Brebner said the giant rats were chosen for the project for their longevity
because they live as long as eight years.
She added that it would give a better
return on the training investment and they don’t bond easily with handlers, so
they would adapt to whoever uses them.
Brebner disclosed that the Endangered
Wildlife Trust had long used dogs to trace wildlife trophies, but rats could
scramble into small, dark places and could climb up containers.
The official
said pangolins, a mammal hunted close to extinction for the unique scales on
its body, which find a ready market in Asia, were the first target.
“The rats
were tested and trained by APOPO, a Tanzanian-based group that pioneered the
use of the African Giant Pouched Rat to find landmines.”
James Pursey, the Head
of APOPO, said the rats would first be trained to sniff out a substance in
return for a reward.
He said the rats would then be taught to discriminate
pangolins from other smells, a process likely to last until mid-July.
“We will
then be developing the optimal method for how to actually test the shipping
containers,” he said. Pursey said if they succeeded, the project could be
rolled out from late 2017.
