A team of sniffer dogs set up at a British airport at a cost of £1.25 million (NZ$2.58 million) have proved adept at discovering small amounts of cheese and sausages but not so good at finding smuggled drugs, a report says.
An inspection of border security at Manchester Airport in
northern England found that during a seven-month period, the six dogs had failed to find any illegal class A drugs, those considered the most dangerous such as heroin or cocaine.
"The deterrent effect of the detection dogs was difficult to measure, but seizures alone represented a low return on investment, given £1.25 million spent on new kennels and the costs of operating the unit," said the report by the Independent Chief Inspector of Borders and Immigration.
Each dog has its own specialty in detecting goods such as drugs, tobacco, cash and meat being illegally brought into the airport by the 22 million passengers who use it annually.
However the report found that although the sniffers had helped customs seize 46kg of cigarettes and 181kg of meat, they had uncovered no class A drugs between November 2014 and June 2015 even though this was a "very high" priority.
