When using animals for the detection of landmines, handlers face challenges of when to reinforce indication responses, as the actual location of landmines in the field is unknown. Anti-Persoonsmijnen Ontmijnende Product Ontwikkeling(Anti-Personnel Landmine Detection Product Development or APOPO) evaluated an inexpensive method to reinforce rat-indication responses in field settings using TNT to contaminate ground area. Rat detection accuracy was high over the TNT contamination after an overnight soak period of 16 hours and detection accuracy decreased as a function of days passed since soaking.
