Six years ago, I wrote a post about APOPO, not knowing that one day I’d have a chance to visit the APOPO Visitor Center in Siem Reap. That makes today a perfect time to revisit this organization.
Founded in 1997 and headquartered in Morogoro, Tanzania, the mission of APOPO is "to develop detection animals technology to provide solutions for global problems in developing countries." They do this by training African giant pouched rats and technical survey dogs, nicknamed HeroRATs and HeroDOGs, to detect landmines and tuberculosis using their extraordinary sense of smell.
Cambodia remains one of the most landmine-contaminated countries in the world, with an estimated 4 to 6 million mines and unexploded ordnance still buried in the soil. Since beginning operations there in 2014, APOPO has destroyed 8,008 landmines, 43,932 items of unexploded ordnance, and returned more than 73 million square meters of safe land to local communities.
These results are made possible by the speed and accuracy of the HeroRATs. The rats can detect the scent of explosives and search an area the size of a tennis court in just 30 minutes, a task that can take a human deminer with a metal detector up to four days. Each rat undergoes about a year of intensive training before being deployed to real minefields. In December 2025, 20 mine detection rats completed accreditation in Cambodia, increasing the team's capacity.
Beyond landmine detection, APOPO has expanded into new lifesaving applications. HeroRATs now detect tuberculosis in Tanzania, Ethiopia, and Mozambique, identify wildlife trafficking products at commercial ports, and they're developing search and rescue capabilities for disaster response.
APOPO has had a big impact in the communities they serve. They’ve destroyed more than 170,000 landmines and explosives globally and returned over 132 million square meters of safe land to communities, freeing more than 2.5 million people from the threat of explosives.
You can support APOPO in many ways. Adopt a HeroRAT to sponsor their training and work, make a donation, shop for merchandise, or visit the Visitor Center in Siem Reap. You can also amplify their message on social media by following APOPO on Facebook, Instagram, LinkedIn, or YouTube and share stories of these hero animals with your network.
