Bees bred to detect explosives? Yes, it is done in Croatia, where landmines remain in parts of the country. Not only have the bees been trained with food containing explosives or near land with explosives, the bees also continue to make honey. Not sure what the EU regulations on such honey would be!
Bees are viewed as being more cost-effective explosives detectors than trained dogs for the same work.
