We used giant African pouched rats ("Cricetomys gambianus") as land mine-detection animals in Mozambique because they have an excellent sense of smell, weigh too little to activate mines, and are native to sub-Saharan Africa, and therefore are resistant to local parasites and diseases. In 2009 the rats searched 93,400 m[superscript 2] of land, finding 41 mines and 54 other explosive devices. Humans with metal detectors found no additional mines. On average, the rats emitted 0.33 false alarm for every 100 m[superscript 2] searched, which is below the threshold given by International Mine Action Standards for accrediting mine-detection animals. These findings indicate that "Cricetomys" are accurate mine-detection animals and merit continued use in this capacity
