Ronin the rat sets new landmine-sniffing record 11 minutes ago Share Save Tiffany Wertheimer BBC News Share Save APOPO Five-year-old Ronin has helped Cambodians reclaim land that was once avoided for fear of landmines A landmine-sniffing rat in Cambodia has set a new world record to become the first rat to uncover more than 100 mines and other deadly war remnants. Ronin, an African giant pouched rat, has uncovered 109 landmines and 15 items of unexploded ordnance since 2021, charity Apopo, which trains the animals, said in a statement. Cambodia remains littered with millions of unexploded munitions following about 20 years of civil war that ended in 1998. The Guinness Book of World Records said that Ronin's "crucial work" is making a real difference to people who have had to live with the "fear that one misstep while going about their day-to-day lives could be their last." Apopo, which is based in Tanzania, currently has 104 rodent recruits, or HeroRATS, as the non-profit likes to call them. The rats are trained to sniff out chemicals that are found in landmines and other weapons abandoned on battlefields. Because of their small size, the rats are not heavy enough to detonate the mines. The rats can check an area the size of a tennis court in about 30 minutes, the charity says, whereas a human with a metal detector might take four days to clear the same land. They can also detect tuberculosis, an infectious disease that commonly affects the lungs, far quicker than it would be found in a lab using conventional microscopy, Apopo says.
